I built a gaming PC about 3 months ago, Everything ran great, until last night.Now my computer starts up but;No beep, so probably no post test?my monitor searches and then displays "check signal cable"mouse deadkeyboard wont lightWhat does work are fans, dvd drive, lights on Motherboard, lights on PS.Interesting side note is I have to push the CPU cooler fan to get it running. Once started fans stays running. So maybe the CPU heated up and died? Could the CPU be fried? Causing the no post test?Any help would be welcomeThanks

Answer:Computer powers up but no beep(no Post)

Replace that fan ASAP...Also swap in a borrowed PSU of the same or greater wattage...

I've got an annoying issue with my PC, my PSU died not long ago so I replaced it but that didn't solve the problem. It revealed new ones.

At first, I would only get a flicker of life from the CPU fan, so I reseated everything and removed any excess cables. With only the RAM, CPU and graphics card connected, my motherboard cycled through and beeped once. I thought all was fine, so I relocated my machine to it's usual spot and hooked it up to the monitor. Switched it back on, no cycle, no beep and no display.

I tried a second motherboard, with only one stick of RAM plugged in, the CPU and a graphics card. Still no display and no beep from POST. I have no idea what's going on, I've tried resetting the CMOS on both motherboards, three different graphics cards, having the motherboard out of the case and all the usual checks.

Quite frankly, I'm stumped. I'm thinking it might be my CPU?

For reference my hardware is -

EVGA X58 1366 socket mobo
ASUS P6TD Deluxe 1366 mobo
Intel Core i7 920 CPU
Corsair XMS ddr3 triple channel
750w Coolermaster PSU (modular)
Nvidia GTX 285 Graphics card
Nvidia Quadro 600

Answer:My PC powers up but no signal on monitor or POST beep

If your PSU died it could have taken your CPU out too. You probably don't, but if you do have another CPU try it.

Hi, this is my first time posting on this site and I need help. I have built everyone in the house's computer and if something goes wrong I can usually figure it otilout and fix the problem. Not this time, I'm about to fix it with a hammer.
My system- ASUS P4SD-LA Stingray mobo with a pentium4 CPU, 2Gb RAM, Maxtor 40Gb SATA HD, ATI 9800XT video card,M-audio Audiophile 24/96 sound card and 500w PSU running Windows XP.
So, everything was running fine until last week. I normally don't shut my system all the way off, I just put it in hibernate but for some reason I turned it all of the way off. The next morning when I went to turn it on it wouldn't boot into XP and gave me a missing file error message ( I forget which one). I ended up having to do a system repair with the install disk starting from XP SP1. When I got to the SP3 disk my CD-ROM drive crapped out on me and I had to swap it for a different one, got repair install finished and when I rebooted it seemed to be OK except I couldn't connect to my network at all. The next time I booted it up I had no display on my monitor, all of the system fans were on, I could hear the HD, but no screen.
I'll try to make this long story shorter, this is what I've tried so far (not necessarily in this order)-
removed all cards, cables, etc. and cleaned the contacts, put them back in.
It ran fine for 1 day, then just a black screen again.

Just bought the laptop 1 week ago; battery charged (fully) will power up laptop stays on for about 10-15 seconds and then shuts off. Connect the power cord and power on; the same issue happens.Pulled battery away from laptop and re attached and tried the power up; same thing happens the laptop will shut down after 10-15 seconds.

Answer:HP CQ 62 powers on, 10 secs later shutdowns

If you just purchased this laptop (assuming it is new), you have a warranty. Return it to where you purchased it. That type of problem in a very new system is not a good sign, probably a weak component that passed initial testing but failed soon after you began using it regularly. If at all possible, get them to REPLACE IT with a NEW one. You purchased new, you should get new (not to repair that one and definitely not a refurbished one [a repair of someone else's defective return])You have to be a little bit crazy to keep you from going insane.If all else fails, read instructions.

Hi, got a bit of an issue that i can't resolve. Basically Since I've put in a temperature gauge for my Kandalf case it's now will not shut down. well it does shut down and powers off ( i also have an intellipulg thing but i'm sure thats fine) everything goes off monitor pc all the lights inside etc... then about 10 seconds later it just turns back on !! Can't see how the temp gauge has done this as all that does is gives a display and takes one power molex so can't turn it back on. Have made sure that it's not on wake on lan/wireless. and turned off wake on usb keybored etc. Please Please help i've been making do with it just going into sleep mode for like 6 months now.

Answer:powers off for 10 secs then back on.

Hi MightyMouse and welcome to Vista Forums

I agree that just having this device installed and only connected to a molex connector should not interfere with your system in the way you described. You could try unplugging it to see what happens. Another thing - are you sure that you are selecting Shutdown and not Restart?

I am desparate for a fix to this problem as this is my son's college laptop, & it is out of warranty.  I have seen similar posts with other Lenovo laptops, but have not seen a fix that works.  The laptop powers up, keyboard lights come on for 2-3 seconds then fade out, fan & hard drive power up & stay on.  Nothing ever shows up on the screen, there are no beeps, no keyboard inputs have any effect.  Lenove says it is a nopost issue, & either a bad motherboard/CPU or memory.  I have replaced the motherboard with 2 different ones of the exact same part #, but get the exact same problem.  I have replaced the RAM - no change.  I took it to a Micro Center who also plugged the screen into another laptop, & said the screen works fine.  Per other posts, I have removed the CMOS battery entirely, I have disconnected the main battery, I have tried many key/power button/reset pinhole combinations - nothing helps.  I can't try bios updates or driver updates or rollbacks because I can't even get to the bios setup. I am completely at a loss at this point.  If it is not the motherboard, not the RAM, not battery related, not the screen, the fan is running, the hard drive is spinning - what can the problem component be? Flex 2, i7, 8GB RAM, 500GB HD (not SSD).

Hi kwebiz, 
 
Greetings. 
 
Based from the symptoms and steps that you have tried , this issue classifies as no post and usually they would have the systemboard checked along with the CPU and thermal system. This may be the same recommendation by local service center most likely. 
 
On similar scenarios the graphic chipset usually show the same issue on most laptops and that users would try relow and reball techniques although would require special tools and techniques to make it work similar on this discussion.
 
Hope this help answer your query. 
Update us how things work best for you.
 
Regards

My X1 Carbon just keeps powering on and off continuously and there is no way of stopping it. It first started with the screen having some funny, shimmering, short horizontal coloured lines during boot up. Then, the keyboard and power button just kept blinking on and off. At first, the power button would blink 3 times in quick succession and then power on and off. Eventually, the laptop would turn off totally. But, when I pressed the power button to start up again, it went into this crazy cycle again. I've tried turning the computer off by holding down the power button, but it doesn't work. The first few times, the laptop would eventually power off, but now, the laptop won't power off at all. The power button now blinks once only on powering up and then the entire laptop turns off, but immediately it would start up again, and the cycle just keeps repeating itself and I don't know how to stop it. The LCD screen remains blank and doesn't seem to switch on at all. Does anyone know how to fix this probelm so I can use my laptop again?

Answer:X1 Carbon 20A7-CTO1WW; Powers up and immediately powers off continuously; cannot be stopped

Good day and welcome to the community.
 
I've not previously heard of the symptoms you're describing. Frustrating, I'm sure.
You might want to try pressing the emergency reset button in the tiny hole on the underside of the machine with a straightened paperclip. (See page 7 of the user guide)
 
Hope this helps.

Answer:pc powers on but no display, beep or anything

First question is: what does it do? Any lights? Fans run? Or is everything dead?

The first guess, based on what you have described, is the power supply is going/gone.
Can you borrow a known working supply to test with?

But if there is nothing happening at all it could be as simple as a case switch.

When I try to power on my Lenovo R61i, the screen shows a Thinkpad screen for a second, then it powers off.I cannot get it to behave in any other way.I have taken the battery out, tried to power on just on mains, but still it does not power on.Has anyone come across this problem before?Thanks

Answer:R61i Powers on - Shows Thinkpad Screen - Powers Off

Hi pvrms90,Welcome to the forum!Try the following:-1.) Unplug the power cord and the battery.2.) Press the 'Power' Button 10 times repeatedly.3.) Then hold the 'Power' Button down for 25 seconds.4.) Put the battery back in and plug the power cord back in.If it shows no sign of life then try removing the RAM and HDD one at a time to diagnose if it boots or throws any errors. If no go then maybe it's the motherboard that needs to be replaced.Hope it helps.

I've tried using multiple monitors.
I've plugged the monitors into the both the onboard graphics card as well as my Nvidia card in the AGP slot. I can't remember if I uninstalled the onboard graphics card.

I've checked inside the PC and found no signs of damage. All fans are running properly.

At this point I'm at a loss as to the cause of my problem, and would greatly appreciate your advice and questions.

I have Dell Dimension 2400 with 2G of Crucial Memory. It is running XP Home edition. It had run updates and was powering off but got stuck for over 24 hours without successfully powering down. I did a hard powerdown by holding the power button until it shut off. When I tried to restart the computer it will power on for a second, power off for 2 to 3 seconds and then power on. No image is sent to the monitor and I do not know if Windows is booting. Checking the monitor it says it is in sleep mode and press any key to wake it up. Pressing any key does nothing. Hooking my laptop to the monitor, it works fine. Could it be the video card or a short? Or could it be a virus?

I am dealing with a TP T440p that was recently built and installed for a user. When in the dock station - when she powers down through normal methods the machien automatically powers back on. When undocked it is fine and of course she can hold down the power button on the dock to shut down but that can be harmful to the system.Anyone have experiene with an issues like this - I have tried docks and setting changes I have seen online with minimal success.Thank you.

Answer:T440p Automatically powers up after user powers down

In the BIOS for the device, do you have the setting enabled that powers it on when the AC is attached?  Shot in the dark with that, but it might be the issue, if the dock is acting like a power supply being attached.

Hi All. I have a T61P and and having issues that i cannot identify. First off, when i turn it on, it will boot if i leave it on my lap but if i rest it on a table, it wont boot. When it does boot up, the Thinkpad icon appears but is distorted with colored pixels (sort of like starry sky) followed by a blank screen with random font appearing ie. upside down question mark, a couple zeroes, etc... all randomly placed.  I cannot run in normal mode. Only in safe mode - when it actually boots, and in safe mode, it is also distorted with the colored pixels/dots. If in the case it does not boot up, the screen remains black and when i hold down the power button to shut down, it will beep once right before it totally turns off. Has anyone heard of this? Please let me know asap as i have ran a harddrive diagnostic that failed and purchased a new hard drive but am not sure if thats the issue. Thank you!!!

Tried isolating the components - disconnected the CD-ROM, HDD, FDD, as well as RAM, and it STILL gives me the same nonsense.It all started when my Mum was formatting some Floppy disks, and suddenly the screen went all haywire (system hang + purple/orange/green mishmash of colours and text)... after that, it just refused to boot up consistently. The only major component I installed recently was a 19" LCD WS monitor (from 17") with a direct power supply from a wall outlet.I can hear the HDD (if its connected) loading, but there is no 'beep' that signifies that the system is loading normally, and the screen remains blank. Disturbingly, it randomly (perhaps 1 out of 10 times) gets past the boot screen, but then hangs at the Windows 'Welcome' screen.Can anyone pls help me. I am at the end of my tether on this.

My Hewlett Packard Pavilion 4450 with NVIDIA GeForce2 MX 100/200 has started powering itself on and off numerous times when it is powered on. This happens before any video is displayed. When it finally "decides" to stay on I get that message that the previous boot did not complete, and press f1 to enter setup or f2 continue. When I have entered setup, I see nothing wrong in the settings, so now I just press f2 to continue.
Any ideas? Does this mean my mother board is dying?
The first time it did this was after chatting in a chat room, and I though someone had run a really mean boot program.
Now though it's doing it almost everytime I power on. I'm afraid to shut my computer off

Pre-existing conditions:

Several months ago, when I installed my CD burner and tried to turn my PC on, it killed my old 230W (stock) power supply, which took with it my MB, video card, one of my 3 256MB RAM chips, and CPU, prompting the upgrade to the above specs. Several weeks of video card instability followed until ASUS released a more mature AGP driver, and other minor hardware issues came and went. Still looking at a rather un-burdened WinXP install. Due to high CPU temperatures with the stock fan, I switched to the loud but dependable heatsink listed above. Before, all that hefty new gear meant that doing anything more than surfing the net bought my CPU past the 180 F (82.2 C) safety threshold of the MB and made the system restart or shut down. With the new cooler came average temps of 110 F (43.3 C) that only rose a few degrees even under great stress. And all was good.

Answer:PC Hardware: New PC, Powers up, No POST. Help!!!

Depending on which cooling fan you have, sometimes it takes a little tweaking to get it mounted on perfectly straight, make sure all the screws are tightened to the same tightness and not tightened too tight(as this can somethimes bend the board causing poor contact). I often forget to plug in the atx 12v connector(the four pin one usually located near the cpu), so you might want to check on that too. Other than that I really don't know what to tell you besides check over everything carefully. Sorry to hear the bad news, hope i can help.

So this morning I attempted to turn on my computer and it will not boot. All the fans turn on but I get no signal to the monitor and no beeps. The keyboard lights up for a second and the DVD drive opens and closes. I tried removing all but one stick of RAM, and moved the one stick around to different slots but with the same result. I also tried booting the computer without any RAM at all and I didn't hear any beeps. Does this guarantee that the problem is the motherboard?

So strange. I installed WC 3 and Farcry.

For some reason, when I try to play the game specially the game itself, it seems my HD powers off and powers on again. That freezes the screen for a few seconds. I try to move it and again it powers off and on again and eventually it freezes or restarts.

I have Sims and it works fine with that.

Is it perhaps I don't have enough power? My power supply is 350W so I thought that should be decent enough.

Currently, I have a 2100+ AMD with the infamous ECS purple board. Just one 16X DVD, with 9800 PRO.

The only guess I have is that the PRO has its own power supply so when it needs some extra juice, it sucks up a bit more from the HD...that's my only guess but that shouldn't happen.

Any suggestions? Is it a virus? Should I do a surface scan? How?
 

Answer:HD powers off and powers on again...when trying to play games.

The 1st thing I do when pc plays up is scan for virus and malaware. Then it's down to process of elimination, hardware or software. If it's hardware it could be your psu. The 350 watt is overall or 'output'? If it's not output it may not be big enough. Also could be driver for graphics card - update anyway. Try tests on DirectX. Is graphics card ram enough?

I have an Acer Veriton M460, I recently replaced the motherboard on it. plugged everything in and then plugged the power in. It immediately started running. The fan for the processor and power supply started to spin but I never had to push the power button on the front. When I look at the button the light never lit up and when I would push the button it wouldnt do anything. When I held the power button in, it wouldnt shut down the computer. To shut it down I would have to pull the plug. Now whenever it would turn itself on automatically, I never heard any beeps or anything, the fans would just start running. So I disconnected everything that wasnt esential, USB's etc plugged it in, still the same thing, unplugged the power button same thing. I pulled that motherboard out and stuck the old one in, *which would work sometimes but not all the time I at least would get some beeps* and the exact same thing happened. Does anyone have any idea what is going on?

I have a Compaq Presario 18XL4 notebook PC that will not boot. I press power and it will spin up the drives, but powers off before the display initializes. I tried on battery and with the AC adapter together and alone. I get no warning beeps or anything.

I haven't changed hardware or bios. RAM is seated. Processor is seated. Hardware is connected to my knowledge.

I removed all hardware including the processor and powered on, and it will just stay on and spin the fan like normal.

I don't even have the display attached at the moment, just RAM and processor but it just powers off a few seconds after I press power just like it was when allt he hardware was attached...

Any clues/help or general ideas of what the issue may be? Thanks for anything.

Answer:Notebook won't boot: powers off during post

If it worked without the processor, maybe it burned out. Check the pins on it, check the housing

You said you tried it with the ram and CPU, have you tried it with just the CPU?

If that works, then your ram is the problem.

Hope this helped,

Hi guys, having a rather odd and frustrating problem.

I purchased a new CPU cooler and had to remove the MB to fit it. Everything went fine but when I plugged it all back in the PC powered on, fans and drives started spining but nothing displayed on the monitor (no error beeps either). After a bit of screwing around I figured I damaged the MB while removing/fitting the cooler so I went down the road and bought a new MB. Went through the install process of fitting the new board, but once again same problem! Power but no display, monitor light just blinks.

I tried a different PSU, RAM and video card but nothing helped.

The only thing I haven't changed is the CPU (don't have a spare). Could the CPU be fried? I don't see any scorch marks or smell anything. When I insert the CPU without the heatsink I can feel it get hot and then cools when I power the PC down (only did for 10 seconds so I don't really fry the CPU). To me this "indicates" that the CPU is ok, or will the CPU continue to heat even if it's dead?

Any suggestions/ideas?

Oh, one odd thing I noticed immediately after fitting the cooler in the original MB was after I powered the PC on the DVD drive made a strange sound and the light blinked. I pushed the eject button but it only came out half way and then went back in. Never seen that before.
 

Answer:PC powers on but doesn't boot - no POST

Have your tried a new MB? maybe somehow if broke something in it. i don't really think your cpu is dead, i have had old processors that i bent pins and dropped and spun around but they still worked when i built older system for family * pins were bent back straight just so everyone know* i would think that something is wrong with your motherboard but thats just me i could be completely wrong. hope you find the problem though

Hey all .. this is a good one and I would so appreciate anyone that can help. I'd fly out to you and shake your hand personally haha. I've built this PC over a year ago and been at it off and on ever since! I start my pilot training and the PC would be great to run Flight Sim X and would help me greatly. Now I'm stuck using an old, cheap, and slow Sempron just to get me online. Here goes:

This is a list of all the parts I ordered a year ago this first time for this pc:

Memory: PQI 1024MB Dual Channel DDR2 PC5400 667MHz (2x512)
CPU Cooling Fan: Thermaltake Golden Orb II Cooler for Intel 775 AMD
M/B: Intel D955XBKLKR Socket 775 Motherboard
CPU: Intel Pentium D 820 2.8gGHz DT 800FSB Socket 775
Video Card: NVIDIA GeForce 6800 GS 512MB PCIe w/DVI/TV-OUT
HDD: Maxtor 250GB SATA-3G HD 7200/16MB/SATA-3G

The first time I assembled everything using all precautions, (I had been custom building PCs for 12 years before this, and had several successful PCs built for myself and others to this point) I went to first up the PC and I got nothing. The monitor got a signal and the light on the power button on the monitor would sometimes go from yellow to green and sometimes not.

I posted this elsewhere and have since discovered that place was inappropriate; sorry.

Fixing an old machine, p3 phoenix bois, and it boots with a single beep, and seems fine until it initialises the keyboard. What transpires i can only describe as an angry successive beeping that develops into a seemingly continuous beep. The background is bizare, at least as far as i understand it, a client brought in 2 machines, the first had swolen caps on the board, which we replaced, and ran successfully for some time. However, the keyboard began to stutter with beeps after post and after re aligning the pins also worked fine. Subsequently, the client brought the first back, the keyboard had begun beeping again, only with more intensity and irregularity, simmilar to a stuck key but more erratic. I sent the client away with a new keyboard and success. However, the client returned again, reporting that the beeps had begun again 4 or 5 days later. Again I replaced the keyboard with, and no beeps. Subsequently the client brought in a second machine reporting that the first had persisted with its beeping issue, and that he had chosen to use another machine at his disposal. As it turns out the second computer had the same issue, solved at least initially with the replacement of the keyboard. The problem still persists however, and seems to have gradually worsend over time. In both cases the same original keyboard may have been used by the client, in the case of the first machine the keyboa... Read more

Answer:Continuous Beep After Post

You sure this client isn't messing with you and has somehow caused this? Are there any *.bat files or something similar that have some code in them to cause this? I guess last but not least, is this an error code that the bios is throwing you due to heat problems or something of the sort.

Just seems a little suspicious.

I have an addendum to add to this thread.  To refresh, my questions focused on a possible mis-match of PSU and motherboard specs:  Is it an ATX 12 Volt 2.0 and above spec problem or a Wattage cap problem?  I posted my questions to the Corsair PSU Forum concurrently and I paste here now, a response to RAM GUY.   "Hi RAM GUY,Sorry I could not reply until now.  Thank you for clarifying the difference between the ATX 2.0 spec and 2.01spec in that the Negative -5 Volt Rail is not present in the 2.01 spec andbeyond.  As I mentioned previously, the Thermaltake PSU that has beenrunning in my 2009, HP i7 Tower for the last 7 months says 12 Volt ATX 2.2on the case and even though the OEM HP power supply says 12 Volt ATX2.0 in spec literature I found on Google, the actual PSU I have does nothave any ATX spec rating on the case.  So I think it is safe to say, mymotherboard does not require the Negative -5 Volt Rail in that it playednicely with 12 Volt ATX 2.2 spec up until recently.Though theoretically there is supposed to be no limit on the amount ofWattage you can use to power your motherboard because the motherboardis suppose to use only what it needs and cap the rest, it appears that OEMscan dial up Wattage limitations if they deem necessary.  Could be as simple HP, not wanting to compete with some of it's HPsProfessional Work Stations, thereby caps Wattage on some Pavilion EliteSeries models to prevent them f...

Hello all,

Preface:
I am building a computer for my girlfriend's mom and today the parts arrived. I built my own gaming computer earlier this year and had no problem. Before that I hadn't built a computer for over 5 years.

The hardware:
Antec Sonata Designer 500 Silver Steel ATX Mid Tower Computer Case 500W Power Supply - Retail
ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD Motherboard - Retail
XFX PVT72SWANG GeForce 7200GS 512MB (256MB on board) 64-bit GDDR2 PCI Express x16 Low Profile Ready Video Card - Retail
AMD Athlon 64 X2 5200+ Brisbane 2.7GHz Socket AM2 65W Dual-Core Processor Model ADO5200DOBOX - Retail
G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-2GBNQ - Retail
Seagate Barracuda 7200.10 ST3250410AS 250GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

*I am using an older IDE CD-Drive from an old computer I have (but I know this has nothing to do with my issue).

My problem:
The computer powers up when I start it, but it doesn't post. Everything seems to be working fine - the CPU fan, case fan, hard drive, optical drive, graphics card, PSU, are all powered on, and there isn't any automatic restarting or shut downs. The monitor just displays a blank black screen, and the power light is blinking like it is sleeping (just as it does when my computer isn't on). Also, there are no beeps (I believe this means it's not passing the power-on self test?).

What I have tried:... Read more

Hello, I can't understand this. I have a w540 with a 2.5" ssd in the internal hdd bay. When I have bitlocker enabled it will not post sometimes, it will just have nothing on the screen and no keyboard lights and the fan will spin. othertimes it will turn itself off after about 15 seconds. other times it will post but after 30 seconds to 3 minutes. It is completely impossible to predict its behavior. Once it starts its like perfect. I removed bitlocker and it works fine. I even wiped my ssd completely, and fully reinstalled windows, reset bios. everything worked perfect. then I put bitlocker on and first reboot, it wont post. Why does bitlocker do this. What is the problem.

It's been three+ years since I built a new comp... Serial ata, PCI-e, dual channel ram, and 24 pin mainboard connections were foreign.

Having everything(sic) connected, my new 'puter powers up, runs without complaint(left it on for five minutes or so, and manually shut it back off), but nothing comes to my moniter(ie: it stays orange/yellowish in sleep mode, instead of green for an active connection).
There are also no beep codes.

Specs:

Antec Smart Power 450w
Asus A8N5X
Athlon 64 3200+
1GB stick of G.Skill
Evga 7600GT

That's just what I'm trying to get it to bootup/display Post with.
I've also:

1x 1GB G.Skill stick
250g Western Digital
NEC DVD Burner

Which remain disconnected/unattached for the sake of my sanity.

Every fan(case, mobo, cpu, gpu) runs, the motherboard and front panel LEDs lightup fine. There is no restart/shutdown of the system at all.
The soft/hard resets work perfectly. CMOS is/has been also set to default.

Both of the moniters I've tried to hookup to the 7600 are Analog(Viewsonic CRT, Dell LCD), and the 7600 only has DVI outs. Thusly I've used the pack-in DVI - RGB connectors. If there's a problem with displaying the inital bios using those and not straight digital, I've not come across it on websearches.

The only other thing that I've read about was the 12v rail needing ample ampage(20+). My 450 Antec allows for 15a on +12V1 and 17a on +12V2.

Answer:New computer build powers up/stays on, but no display/post/bios

Looks like you'll have a real nice system once you get it up and running!

Couple of questions:

1. Do you have both of the power connections to the motherboard? There should be two, the 24 pin and the 4pin.
2. Do you have the power connection going to your graphics card? Most newer cards (but not all) require a 4pin molex connection from the PSU directly to the card.
3. Did you hook up the case's speaker? It would have been one of those tiny annoying to connect wires (assuming your case has a speaker - they are very small and hard to find). If your case has a speaker, this is very useful. The beep codes may tell us what is wrong.
4. Did you use the riser pins into the case's screwholes (under your motherboard) before you installed the motherboard into your case? (some cases have the riser pins pre-installed for you, some don't).
5. What speed ram are you trying to use? Do you have a different make of ram you can test in there?

Also, take a look at the LED lights on the motherboard and see what color they are both before and after you hit the power button.

Hey all,

I just recently got a large hardware upgrade (new mobo, video card, psu, RAM) and have run into problems getting things up and running. Here are my new specs.


Asus P5N-D 750i
OCX GeForce 8800GT 512MB
OCZ DDR2 PC26400 RAM (4GB package)
Corsair TX 650W Power Supply
Note: Using an Intel Pentium D 2.66 mhz processor from old system

I had a friend who is very experienced with installing computer hardware come by and over-see the installation. Everything was double checked that they were installed properly. When we powered on the system we got a long continuous post error beep coming from, i assume the motherboard. We tried disconnecting the RAM (didn't have another stick of working compatible DDR2 RAM to test with) and still got the same thing. My buddy seems to think my CPU may be the problem, as the video card was tested to work fine.

I guess i should also mention that last week i had a PSU malfunction that may have fried my old motherboard, so there is definitely a possibility that the old PSU also took the processor with it as well... Anyone have similar issues or know what a continuous loud post error beep on an Asus motherboard means? Any help would be greatly appreciated.
 

Answer:Long continuous post error beep!

Well it depends a bit on what BIOS you have what a continuous beep can mean but in general it means there is a memory error but can mean a system board failure or even a PSU failure.

So what BIOS do you have?

I have just built a brand new system (specs below). I installed a new Windows 7 (will be migrating my old one over later if the force is with me) and I noticed that when I shut down Windows, the computer not only powered off but all the lights on my motherboard went out too. I was unable to switch on the computer with the power button.
The only way to power it back on was to switch off the PSU for a couple of seconds, power it back on and then the computer would power on with the switch as normal. When it is switched on it is perfectly fine and has been running overnight without issues.
All parts are brand new.

HI
Long time no see, friends.
My beloved I570 is acting up, probably some sort of Alzheimer or similar.
Here is what happened, will try to be short.
Initially I was using PCIE SATA card to attach 4 more HDDs to the system, then SATA card died (already second in this PC), so I decided to remove all extra HDDs sitting in the case.
Did all standard precautions, including grounding etc. In order to remove HDDs I had to clear MOBO of a lot of cables and remove GPU. Long story short, after I put everything back together and attempted to boot up, I got long continuous beep and WIN7 sliding bar freezes almost at the end, no further activity, just a long beep. BIOS was not accessible as well.
So, I removed GPU, pull out MOBO 24 pin PSU cable, removed CMOS battery, did multiple 30 sec press and hold power button thing, left everything dead completely for about 30 minutes - completely reset system clock and all BIOS settings to default. Also, swap RAM (I have 2 sticks in slots 3 and 4) places. Put everything back, fired up, went to BIOS and fixed everything, DONE, rebooted and everything went back to normal.
Multiple restarts were OK, did also a few cold reboots with some minutes apart - all seems to be normal. Turn it off for a day or so.
Now problem is back again, like nothing happened.
Please, help if someone actually can. I checked multiple thread here and all over the WEB. My keyboard is clean, RAM was resettled, all connectors are firmly attached. This doesn't make any sense.

Asus A7S8X Motherboard - I had purchased this board from tigerdirect. The setup was easy the first time... But I made a stupid mistake and forgot to find my win XP OS cd. No biggie =). I put my old system together. Powered by a rock solid PSU. Mind you I had the same problems when I first did it. But it seems like my second time around I have tried everything and I get nothing. Originally I got bios and everything was well. It was a rock solid board. Im speaking to you with the original computer so I know the component used in the upgrade are good parts. PSU is AWESOME 400 watts. So I know im not overtaxing the new system. I have taken the motherboard out of the case on a non-static piece. This still does the same thing. Can anyone elighten me on what else could be causing these problems. Im not stupid I have been building computers for awhile now and this has just stumped the crap outa me because the board did have simialiar probs the first time then I got it to work!

Answer:A7S8X Asus motherboard - Powers down 1-5 seconds after startup

As my intention with this thread is to help myself as well as others. I have been pondering some things that could do with the power problems many could face with motherboards. The following things could help others however has eighther not solved my problem or I will probably never know.

______________________________

1: The capacitors have been torn off the board causing unregulated power running thorugh your board ( Can cause a wide array of problems even not powering up at all )

2: PSU has gone bad and need to be tested to ensure the problem. A good PSU can cost 50$ more then you need to spend if you just test it! Dont jump to conclusions about the PSU is my advice!

3: Your PSU is not powerful enough to run the motherboard and all its periphrials.

* 300-400 watts is good enough for most mid-end gaming machine!

4: Read your instructions well and always be sure you have your power switch hooked up correctly!

5: I have not proven this myself but I hear some boards dont like to run inless the CPU fan is hooked to the motherboard!


Thats my input I would give on somone with the same problems. However this doesnt hold 100% true to my situation!

You can read the saga version of this problem in the topic I posted called "blank screen bootup". The short version is that I ordered a new motherboard (Shuttle AK35GTR2) because I was having this problem with a Soltek board. Now I am having this problem with the Shuttle board after I tried reversing the fan position because I had lost my video display.
 

Answer:Machine Powers up, then powers down

fist off, never reverse any of connections for the fans, they are keyed for a reason, plus you mainboard may not be the problem, your power supply may not be adequate or is beginning to flake on you. try swapping that out, its more often than not a power issue that if it goes unseen, can wreck everything you plug it into. make sure you use approved supplies only, its better to pay a few extra bucks for quality instead of quantity, because a psu is only as good as the tranformers and capacitors within it.

New everything, but for sake of simplicity all I'm using is literally my motherboard, PSU, and that little speaker thing that beeps at me if need be.

I short the power to turn it on, it should beep at me, it does nothing for a few seconds, then powers down.

My buddy at work told me to try this when I told him of the original problem. Which was... I had the CPU, HSF, RAM, and Graphics card installed.
The result was when I powered up it (the CPU and PSU fan) spun for about 4-5 seconds, then powered down.

Without the graphics card the same thing happened.. and I tried with 3 different sticks of ram.

Motherboard dead, or something else?

I am installing a new mobo ( Shuttle AK35tgr2) after a series of problems with my former Soltek board which culminated with a problem in which the computer powers up and then powers down after about a nano second.

Well I'm having the same problem with the Shuttle.

First the problem was no video and no beeps from bios and in the process of trying to solve that I readjusted by CPU fan ( actually turned it around) and after that the computer powers up for a second then powers down.

I tried tightening the mobo screws and then it powered up for two or three seconds before shutting off.

I am thinking of changing the fan. It is about the only component that isn't new or hasn't been tested.

I don't get any image on my monitor and there are 4 LEDs that say Phase next to them on the motherboard

Phase 1 is green, phase 2 is green, phase 3 is orange and phase 4 is red. I'm not sure if that means anything.

But if one depresses Ctrl + Alt + Del it stays powered on, but do nothing else until it powers down and stays off after a few minutes of this suspended state. (Note we haven't even gotten to POST ever, so no boot screen, Vista, Safe Mode, etc.)

I stripped it down--removing all memory modules, the hard drive (drive runs, contents are intact), and the optical drive. Upon start up the same routine took place and there were no beep codes!

I followed the instructions for resetting the BIOS (Pull battery. Tested it: 3VDC registering).

I've done this with battery only, power adapter only, and both. I get the same results regardless.

So the question: Is it dead? My opinion: Yep. The anomaly that keeps me wondering (and this may be just nothing): Why should Ctrl + Alt + Del do anything?

Maybe just answer the first question.

hi
I have a ASUS P5N-D

the motherboard speaker beeps once each time I turn my computer on.
is 1 beep okay ??

I looked for a beep code list in my manual but couldn't find one.
I went to ASUS. I couldn't get there "faq" support section to list one.
kept saying no results found.

are most beep codes similar across all mobo makers???
in Google I did find where one forum had listed 1 beep as a memory
refresh rate error
but it was posted in 2002. so I figured it was out of date,

I receive the following beeps (9 beeps or perhaps 8...not sure)...

Beep codes from AMI website:

8 short = Display Memory Read/Write test failure
9 short = ROM BIOS checksum failure

If 8 is the correct number is that memory on my video card or display memory thats on the montherboard?
If 9 is the correct number is the ROM damaged beyond repair? (open up that wallet )

Hi guys, this is probably the most helpless i've felt in a long while and i'm hoping you guys can help me out here.

So this is what happened,
1. I've been working on a very old HP Pavilion 6418 desktop which came with a Slot 1 PII - 400 Mhz processor.
2. Managed to purchase a Slot 1 adapter which supported Coppermine processors, installed it and things were going pretty well till this evening.
3. The computer is factory locked with a 100 Mhz FSB and I was desperate to get that up to 133 (to utilise the full potential of the 1 Ghz / 133 processor). Now the interesting thing to note is that the motherboard has only 1 of the 3-pin FSB (FS 2)terminals out of possible 4. The leads 1 and 2 are shorted out on the said terminal.
4. Having read a lot about overclocking and how easy it had been for some guys, I decided to experiment a little, so soldered the 1st & 2nd points of the 3 non existent FSB terminals section at back of the motherboard, i.e. FS 0, FS 1 and FS 3, and decided to take a look, if it was successful. Contrary to my expectations, the computer started but did not sound the system beep, on connecting it to the monitor, there was no display, system beep or the POST screen.
5. Then I removed the solders from the 3 FSB points and tried to check if the computer would come back to it earlier state. Sadly, this time too there was no system beep and when I connected it to a monitor, there was no video, POST screen, etc.

I'm hoping you guys can help m... Read more

I've got a problem I just can't see any way of fixing.

My son's Acer Aspire laptop is about a year old and has worked just fine. Recently he decided he needed to free up more room on the hard drive and figured he would uninstall some components from his Microsoft Office Standard Edition 2003. Not sure exactly what he took out, but now the computer is in a continuous, never-ending loop of:

The Windows Installer box comes up saying "Preparing to install...". It seems to "flash", like it starts to go off then pops up again. Several times.

Then a box comes up saying:
Microsoft Office Standard Edition 2003
Installing Error: File not found
A required installation file SKU112.CAB could not be found.
Original installation source required.

It says to to browse for the source, so I put in the CD and choose it, but then the following box comes up:
"Error 25091: Set up failed to change the source"

When I cancel ANY of the boxes I mentioned above, the "Windows Installer Preparing to install" pops right back up again. Hit cancel on it and it pops right back. Again and again. It never goes away.

Sometimes a box comes up saying:
Please wait while windows configures Microsoft Office Standard Edition 2003"
But the progress bar never budges. Left it up 24 hours even.
Then I cancel that and - yep - the Windows Installer preparing to install jumps back into its loop.

This problem has been happening sometimes after i move my pc, whether it be turning it on its side, moving it in a car, etc. Basically, after ive moved the pc in one way or another, and try to turn it back on, it will sometimes shut off again after about 10 seconds, before the boot screen appears. I can fix this usually by tilting the case back on its side, shaking it gently etc, but it usually takes multiple tries to make it turn on properly again. but its really annoying because im afraid to move it now. Note that it is not a hardware issue as when the pc IS on, its never suddenly turned off, it only happens after i move it.

my guess is perhaps a short-circuiting issue of some sort, but id like an expert opinion on this and perhaps a solution or troubleshooting guide.

Gulp! Powered on and went to the BIOS and looked around.  Nothing changed. Saved and rebooted.  Same, same.  Ok, let's remove the USB floppy drive completely.  Did.  Same, same.  Oh, NO. Powered on and same, same. Stare at it for a while. Went to the patio to burn one and think.  Decided to call IBM and find a service center. Came back in and tried one more time.  Voila. Have no idea what happened or why.  Computers are not good for your health. Finished the afternoon with cold ones. Anyone have a clue?

Last night while just running through some web sites I encountered the dreaded BSOD ...

Pressing the power button immediately powered off the machine (vs. the 3-5 second hold to hard reset, never a good sign in my book).

Upon powering back up, I am presented with the same "back lit black screen" for 3 or so minutes, then the machine seems to reset itself (screen powers down) for about 1 minute... rinse and repeat. I've removed the battery and let it sit without power, same result. Overnight cold reboot, again same result

This is my first PC build and I am having an issue. The PC will only power on for like a half of a second. Also to even get that half of a second I have to turn the power supply switch off for a minute, then turn it back on, then press the power button on the front panel once, then nothing happens, then press the power button for a second time and right when I let go it does it's half second power up. Then I try the power button again several times and it does nothing. I have to repeat those steps to get the carnival ride to light up again for a half of a second. At first I was having a problem with no power at all and discovered I had the CMOS jumper on the wrong setting "rookie mistake." After discovering this I had already taken the motherboard out of the case with just the DDR, CPU, and CPU fan attached. I went ahead and shorted the power switch pins and it did it's half of a second power on routine. So I went ahead and assembled everything, thinking that everything needed to be attached and it did the same half a second power routine. I live in the U.S. and have the voltage set to 115. I did the power supply test where you take the paper clip and short the green pin with the black pin and the power supply came on and stayed on. A few things I noticed is that it is a 420 Watt power supply and theres a big sticker that says for Pentium 4, but I have a Pentium 3.

Pentium 4 power supplies are sh** they dont last long, last one i had left burned marks in my motherboard due to a short. Never buy those brands just because they are cheap and unreliable.
300W is the minimum for a standard PC to function properly, so ur fine with that .
Try a different Power Supply because to me it sounds dead, even tho it power on with the paper clip trick it can still be dead.

Hi guys, having a rather odd and frustrating problem.

I purchased a new CPU cooler and had to remove the MB to fit it. Everything went fine but when I plugged it all back in the PC powered on, fans and drives started spining but nothing displayed on the monitor (no error beeps either). After a bit of screwing around I figured I damaged the MB while removing/fitting the cooler so I went down the road and bought a new MB. Went through the install process of fitting the new board, but once again same problem! Power but no display, monitor light just blinks.

I tried a different PSU, RAM and video card but nothing helped.

The only thing I haven't changed is the CPU (don't have spare). Could the CPU be fried? I don't see any scorch marks or smell anything. When I insert the CPU without the heatsink I can feel it get hot and then cools when I power the PC down (only did for 10 seconds so I don't really fry the CPU). To me this "indicates" that the CPU is ok, or will the CPU continue to heat even if it's dead?

Any suggestions/ideas?

Oh, one odd thing I noticed immediately after fitting the cooler in the original MB was after I powered the PC on the DVD drive made a strange sound and the light blinked. I pushed the eject button but it only came out half way and then went back in. Never seen that before.

They told me the other day that the problem is caused by Windows task Scheduler.

I explored the Task Scheduler, and modified every task to run only at log on. The laptop still powered on every (?not sure about every day, but it did and woke me 3 times since the change) day at 6AM.

The Task Scheduler log does not show any "Last Run Succeeded" earlier than me logging on, so the problem might be somewhere else. HP support will not help me and told me I have a defective power button and told me to contact local technical support. Can a defective power button make my laptop power on at 6AM and ONLY 6AM every day, independently of where (office, room, living room) and how (on a table, in a bag) it is stored at the time? My guess is no, but I can be wrong.

If you, in any kind, can help me on this, I would be very thankful!

Answer:Powers up at 6AM

Hi and Welcome to TSF.

I can't speak directly to your question about the power button, but I would offer a suggestion to check the Event Viewer for all activity preceeding and including 06:00 hours. There is an area specific to the activities of the Task Scheduler (TS). This may allow you to somehow prove to HP that TS is not at fault in the 0600 wake-up calls. Here is a screen shot:

Event Viewer - START | type eventvwr.exe i the start search box | select same

If you need assistance with the Task Scheduler or Event Viewer, post again.

Regards. . .

OK, quick background: I am a software developer and have built perhaps 30 systems in my life, and this is the first time I have every been this baffled. I have come here looking for help! Thank you in advance!

Last week I woke up and walked over to my 6-month-old dev machine (it has worked flawlessly since Dec 07). It was hibernating. I moved the mouse, then tapped the space bar, but the system didn't respond. I hit the reset button and the system restarted. Here's where the problem is:

The system comes on, stays up for 4-5 seconds, there are no beeps and it does not post, then it shuts down. It repeats this over and over until I shut the power supply off.

Now then, before you give any advice, here is what I have done:

I assumed it was the power supply, so I have replaced it twice. The current PSU is a Antec 850watt unit. I've tried multiple outlets and a different surge protector but the system still does the same thing!

Then I assumed it was the Motherboard. I first tried a new ATX micro board from a local shop (the system still did the same thing) then I ordered a new MoBo from NewEgg. The system still does the same thing.

I had the CPU checked out, and it was fine. Still, I bought a new one just to be safe and the system still does the same thing!

I have replaced the video card with one that I know works (to prove it, I am using it now on this system to post this message). The video card swap did nothing- the system still did the same t... Read more

Answer:PC powers down and up on its own

Oh, I wanted to add that I have removed the wires going to the front of the PC (the power switch, reset button and HD LED wires), just to make sure those weren't shorting out. I can of course turn the PC on by touching the Power SW pins with a screwdriver...but of course, the system is still exhibiting the same problems as noted above.

Answer:PowerS.exe ???

Hi!

Could you please do the following:

Go to http://www.tomcoyote.org/hjt/, and download Hijack This.

Unzip, doubleclick HijackThis.exe, and hit "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log somewhere, and please show us its contents.

Most of what it lists will be harmless or even required, so do NOT fix anything yet.
Someone here will be happy to help you interpret the results.

I have a 8 yrs old desktop with Asus A7N8X motherboard with Nvidia nForce2 chipset & windows 2000 pro.
Computer is on, cd opens and closes but no image is present on the monitor. It emits a beep (1sec long) every 5 secs as long as comp is on; the reset button stops the beep but it returns as soon as I let go off the button. I also disconnected all the peripherals, but beep continues.
Check with the website, but this beep is not on their code list.
Monitor and mouse are relatively new. About a month old.
Any help out there?
 

Answer:Solved: no boot, no image, one beep every 5 secs

Built a system from old and new parts. This has been a disaster from square one. Originally had a Gigabyte P45 board that was faulty. System would never stay on for more than 2 minutes in BIOS, with only CPU, Mem and Vid card. Tried every possible scenario, different memory, different power supply the works, that MB was not working. So RMA'ed it and got the Asus board.

Now have had some issues as well with this system, but its at least up and running. Was extremely unstable with 2 sticks of memory and so far seems OK with 1 stick if I don't do any loads on the system. All the other issues to this point I hope is moot and won't bring them up unless needed.

If I run a game Team Fortress 2 or Left4Dead system powers off after a few minutes. Check temps on Processor and Vid card, not overheating. Checked in BIOS checked in windows. Have tested each mem stick individually using memtest86, they each passed. I tried is once using both sticks and PC powered off after maybe a minute, didn't try both sticks again.

Ran chkdsk on both drives, no errors. Decided to download SiSandra and run a CPU load, this resulted in the PC powering off after 30-60 secs. So can rule out the video card. Could this rule out powersupply as well?

Now would any of this indicate an actual problem device? Like is this definitely the CPU or the Memory or the Power Supply, maybe the Motherboard? I want to fix this and get a stable system I can use, but am running o... Read more

Answer:PC powers off under load

Hi m8, I have just built a system, not so different to yours, except I have the 9800Gt and only one hard drive.

I had a 500w PSU in it to start with and it would do the same thing.

So I upgraded to a 650w and that sorted it.

I'm not saying it is the same thing, but you could buy a new 700w PSU try it out and if it dont work then take it back.

Hi Geeks,

haven't been in 4 over a year. PC been perfect! Suddenly warranty runs out and a month later, this... rolleyes

We have a corrupted boot.ini file on Windows XP Media edition. The computer powers up but will not start.

We have 3 available alternative PCs
- at home: laptop of same age with Windows XP
- at home: Really old PC with Windows XP
- at work: PC with Windows Vista.
Can they help?
Can the HDD from an XP PC simply be detached and re-connected as an XHD (we already have an XHD unit) to any of the above for repair or at least data retrieval?

Also is it possible to simply "reboot" from the system disk rather than "re-install"?

Is there any other way to repair this without losing all the data, i.e. wiping the disk? Yeh, I know i should have backed up, but you know how it is when distracted online, you 4get!

Sorry, I'm a good site-builder, but I'm b.u.jiggered at this sort of thing.

Thanks,
Jon
 

Answer:XP: powers up, won't startup

How do you know the boot.ini is bad? What is the error message when booting?

Do you have an XP installation disc? (Recovery Console and the bootcfg option should be able to rebuild the boot.ini)

Adding the HD through an eXternal USB enclosure should make data retrieval relatively easy and is definitely an option.
