Computer Will Not Turn On

Question: Computer Will Not Turn On

Ok, here's the deal:

I had to update my motherboard back in May, along with my video card and chasis. Everything was well and good until one day in July, my roommate was playing LotR: BfME and all of the sudden it just froze. Nothing happened whatsoever, I tried everything. So, I resorted to a hard reboot. Next thing I know it won't boot up. Nothing happens on the screen.

So, I took the compy back to the shop that I had worked with before to get the new mobo and such, and after some testing they claimed that my mobo (socket 478) went bad, so they got a new one under warrenty. Next thing I know I get a call from them claiming that it was not the mobo, it was my processor. Evidently a bad chip, though I have been using it for the past three years (P4 3.0ghz, 800fsb, HT).

So, because I really had a hard time finding an affordable chip for the 478 socket, I found a deal on newegg that gave me an AMD mobo and chip combo. So, I just got it and replaced it tonight. I hooked everything up correctly, and hooked the external parts up. Nothing on the screen happens, though all the lights and fans work fine.

I tested my monitor by hooking it into an old laptop, works perfectly.

I do not get a POST beep until I just have CPU, RAM, and IDE1 (CD / DVD drives) hooked in, yet still nothing on the screen when I turn it on (the new mobo has onboard video, I have tested with both my video card and this). The beep is just a regular one beep.

Any ideas?

Thanks in advance!

Answer: Computer Will Not Turn On

First thing, clear cmos, either by jumpers if you know which ones or by simply pulling plug on power supply and removing m-b- battery for a few minutes, i guess your ram may not be compatable with your new board, and possibly your power supply. ide 1 or primary is for your hard drive, secondary is for dvd-cd rom. ed

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

Answer:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

I just put together my first computer 6 months ago. It abruply shutdow in the middle of writing a paper for school. I couldn't turn it back on right away. after trying a few times, it turned on. All the fans are working even the fan on the power supply, the motherboards lights are on. My graphic card in on the motherboard. I think it might be my power supply because when I first put it together I didn't plug in the smaller power connection to the motherboard and the same thing is happening, black screen. It's like my computer isn't giving my monitor any feed. I will have more info when I get home. I can't get in to bios or safe mode.

I am using a client computer that is connected to a modem via a LAN cable which is in a neighboring house as far as about 50 meters. The host computer is there. The host computer is only using Internet Connection Sharing (without a router) to share its Internet connection with me. Within this network there are only two computers, the one I use (as client) in my house and the other one is the host computer as I mentioned earlier.

How do I know that the host computer is being turned on or off?

The purpose is to know so that I can use all the bandwidth from the modem when the host computer is not turn on. Because there are no restrictions on bandwidth from the host computer, and I just wanted to use all the available bandwidth only when the host computer is not turned on.

Both computers use Windows 7.

after serching all night to find out why his computer is in limbo, i leave my brother's house without finding needed help. his computer won't turn off...the fan, a couple little lights until he unplugs it from the wall. first, the computer did a restart all by itself, he said, then it would not turn on, except the fan and little lights inside that won't turn off. he took out the hard drive and it functions in his other computer...he puts the hard drive back into the new computer and it will not turn on or completely turn off that fan. he tried the "hold the on/off button for at least five seconds" step and nothing changes. he has had the computer for a year and a half, so he really wants to figure this out. how can he even get it to turn on so he could do a safe start up? so far we cannot find a way to troubleshoot. he have checked the cords, perhaps there was a freeze up that began this loop and that's why the fan stays on? please say this is something you have heard of and there may be a solution. the advice we have found usually goes back to buying a new computer. thanks in advance, tea

I use my laptop for school and, by keeping it on power saving mode, usually get through two school days without charging my laptop. Ever since I've downloaded Windows 10, (1) my computer doesn't shut off all the way when I close it, which drains the battery, and (2) every time I charge it, it turns off the power saving mode, which is really annoying. This is especially annoying when I don't notice it isn't on and my battery drains even faster. Is there any reason it won't turn off? Is there a setting I can use to keep the power saving mode on at all times?

Answer:Why won't my computer turn off all the way and why can't my computer stay on power saving mode?

Your system might have a virus, try to scan using Malwarebytes, Superspyware , Trojan-Killer. Restart your system then try to download Hitman Pro then Run it. Then optimize your system using Ccleaner. Hope this would help.

Hi TheRealDanny.

The crash dump (a Stop 0x3B one) is not saying anything in detail about the probable cause of the BSOD).

Test your RAM modules for possible errors. How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
If it does not show any error, enable Driver Verifier to monitor the drivers. Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.



   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.



   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

As the title said, my computer freezes during games. When it freezes the screen just stop at the last frame (so no black screen or anything like that) and I can hear the game for about a second before it turns to a low clicking sound. At which point I have to manually shut down the computer and restart it. Nothing else works. Then I get the usual question of how I want to start the computer, I always pick “start normally” and it’s like it never happened.

I think it’s because the GPU is overheating, because that’s the only component that’s really hot. When I check the temp while playing it’s usually building up to about 60C (24-30C on idle) and stays around that number. And it fells really hot when I touch it after it’s happened. The only problem with that theory is that I can play every game out there usually on the best setting (haven’t tried every powerful game out there) and not a single problem with lag or such. Then again, I’ve never had that problem with MW3, and the temp stays around 50C on that. Not to say that the GPU is really that great. It’s average at best, but I’m not a hardcore gamer or anything so figured I didn’t need the best.
I built the computer myself in June 2011. And it went fine without any problems until maybe 6 months ago, not really sure when it happened.

Answer:Computer Hangs When Turn Off Computer Selected In Windows

Welcome to BC! There are many possible causes, however there is one common cause. Often XP's exit sound file gets corrupt and if it does not run then XP won't shut down. I am not sure based on what you have told us so far if this is the issue or not, but let's see:Go to:Start > Control Panel > Sounds, Speech, and Audio Devices > Sounds and Audio Devices > Sounds tabUnder Program Events scroll down until you see Exit Windows. Highlight Exit Windows by clicking on it once. Then under Sounds choose None. Click Apply and finally OK. Reboot if possible, or shut down computer and restart manually. Once it is up and running, shut down computer by going to Start > Turn Off Computer. See if it will shut down on it's own now.If it does, the only difference will be that you will not longer hear the 2 seconds of music that XP usually plays as it shuts down.

First of, my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.

But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.

Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so.

My question, Is the monitor responsible for the restart and what could be the reason for the flickering?

Welcome Pokeman5 to the windows 7 forums.

The graphics card might be your culprit. Please update your system configuration settings under user cp so that others can maybe help you.
Usually the monitor won't stop your machine from booting. The graphic card most likely be the cause.

There is also the possibility that your power supply could be defective or going bad. Lots of possibilities.

so please help/B]
 

Answer:Solved: computer beeping sounds when i turn on computer

There are three possibilities here, all related to your memory.

1) You have forgotten to fit your memory back in.
2) Your memory isn't properly seated in its slot(s)
3) You have killed your memory because of not following antistatic procedures.

I'm suspecting it is either 2 or 3.

Ok well, my computer is pretty old, but its not THAT old, it has always worked very well, and all of a sudden one day it froze and i tried turning it off but when i went to press the power button it wouldnt turn off, no matter how many times i pressed the power button. so i had to turn off the power switch in the back of the computer. it did this consistently so i decided to format my computer and delete the partition stuff like that, but it still did it, and i even virus checked and there were no viruses.

my computer freezes out of nowhere at random spots (startup, windows, my desktop, etc) and when i try to turn it off the power button doesnt work so i have to turn it off by turning off the switch at the back of the computer, please help me, i don't know whats going on!

Answer:URGENT PROBLEM: Computer freezes, but can not turn computer off

Try holding the power switch in for at least 4 seconds. There is a entry in BIOS for instant off and 4 second delay. Yours is probably set to 4 seconds. Delay is good as it prevents accidential power offs from hitting the switch by mistake.

If you are hiolding the switch in and it isn't powering down there are two possibilties. Switch is defective or connector has came off the header.

Just got a new to me P3 computer up and running. Sometimes during star up it does not recognize the PS2 keyboard. Which makes it hard to go into my password protected User ID. When trying to shut down it will keep a few things running like some fans and the CD drive. But it does not sound like the Hard Drive is spinning.

If I use the XP to shutdown it goes into this limbo stage of neither off nor on, same goes for the power button on the front of the computer. It will either start up the computer or turn it to the limbo mode. Upon starting up, I can use the mouse to get it all the way into a non password protected XP users screen but can't do anything without the keyboard working. In the process of setting up I have had everything working earlier today but this keyboard and limbo status has been an intermitent problem. What should I try?

There also would be these little blue lines on the computer screen (Sometimes their would be alot of the lines and sometimes the lines would be made by the trail of my mouse).

- Un-installing and re-installing my graphic card (Nvidia Geforce4 MX420 graphics card with TV-Out) that came with the computer.

- Rolling Back My Graphic Card.

- Updating My Drive from Windows Update.

- I've tried using a program that test my computer and tells me whats wrong with it. It said I got a problem with something like the VIDEO MEMORY CARD and I don't know what that is.

Hi all.
I moved out of a 14-year-old case (Gateway) and into an Ultra brand Gladiator mid-tower.

I have an EVGA nForce 650i Ultra Motherboard, and a "Power Up" brand 450-Watt power supply.

The setup worked fine in the old case, though Windows was freezing regularly after 15 minutes. I figured that was related to the hard-drive, since it wasn't tightly mounted, and I wasn't using enough cooling fans. So I got a new case and cannabalaized a fan from an old computer.

The power outlet and cord are good, and I swapped out the power supply with a 230 watt unit, and pulled the switch from the old case, but neither powered on the computer. Nothing seems out of the ordinary with the switch on the case I bought.

Did I buy a defective unit? Is there something I'm missing or should try again? Something else? Thanks for the help.
 

Answer:Changed computer cases, now computer won't turn on

Have you considered that going from a 450 psu to only a 230 might have something to do with it?

Is the motherboard shortening out by any part of it touching the case?

Hello there, recently, I've been having an issue with my PC. Randomly, all peripherals (Monitor, Keyboard, Mouse, Speakers, etc.) turn off, but the computer stays on, and I need to turn it off by flipping the power off, and once I turn it back on, it boots normally and such. Like I said, the times this happens seem to be completely random, though I believe it has only happened at night, but that may be just coincidence. I have used virus scans, and nothing has come up, so I don't believe that's the issue. I haven't made any significant hardware changes recently either. Does anyone have an idea of what could be happening?

Thanks in advance
 

Answer:Computer peripherals turn off but not computer itself?

Get into the motherboards bios by pressing a key noted when you first power up the computer. Look for "hit F? for setup" or something like that. Reset the bios to defaults

Hello everyone:

Yesterday, I went to turn on my computer and the minute I hit the power button to turn on the computer, the computer came on, but then turned off right away. Then it turned on again on it's own and ran for a few seconds this time but then it turned off. And then a third time it turned on again and stayed running until I turned it off.

Now, when I turned it on, once the power LED light would light up, that was when the computer turned off right away. When it came on both the 2nd and third time, none of my LED lights would light up. Also, nothing would come up on the monitor either.

Yesterday, what I did was unplug all of my power connectors such as the LED's and switches. Unplugging them and plugging them back in fixed the problem usually.

Come to today. Went to turn on the computer, did the same thing as yesterday. unplug the power cables again and plug them back in and it worked right away.

Since it did this again, I decided that I need to look into this problem further to see what was going on. First off, I blew out what I could of dust that was in the computer because the can of compressed air ran out and I don't have anymore at the moment. Then I started doing some more looking around to see if anything looked abnormal which it didn't to me. So then, I hook up the computer after unplugging it, go to turn it on, does the same thing again that it did yesterday. However, this time when I tried unplugging and plugging in the LED and sw...

This problem is completely baffling me. Any help with this would be greatly appreciated.

Here's what's happening. When I switch the power supply on, leaving the off position, the computer instantly comes on, regardless of the on/off state it was in before. The fans all come on, the GPU fan is at full blast (I've never seen it on so high). And it will remain to stay like this appearing to do nothing, appearing to be "locked". And then, if the power button on the front of the computer is pressed the fans go back to normal, and the computer sounds as if it's booting a normal boot.

Then most recently, after trying to debug this problem for a while, if after being in this "locked idle 'on' state", the power button on the front is pressed and the computer starts "booting", the mother board's speaker starts beeping. 3 long beeps, a pause, then a continuous repeating long beep.

What I've done to debug this is take out then video card, switch on power supply. This results in the computer instantly turning on into this locked state. Then I tried taking out the RAM, switch on the power supply. Locked 'on' state. Take out every single other device, keyboard, mouse, all SATA ports, and miscellaneous PCI cards. Power supply on. Locked 'on' state. And all leads to the same thing happening after the power button on the front is pressed.

Here are my system specs:

Answer:Computer Won't Turn Off

Continuous beeping typically signifies faulty hardware...motherboard or power supply depending on the BIOS brand.

sup,

i just got my six channel diamond DT-688 PCI sound card in the mail and the thing is giving me some crazy problems:

after some time trying to find out what the problem was it came down to the fact that as long as the sound card is inserted into any of the PCI slots the computer refuses to turn off as long as the power cord is attached to it. i installed the drivers correctly and the sound card works perfect, except for the major problem that it won't allow my computer to turn off!

i checked the bios, reinstalled the drivers, attached it to different pci slots, and took a look at the windows xp power saver options. i even messed with the jumper cables on the card itself and that made no difference what so ever.

my friend and i came to the conclusion that the card is defective but i'd rather find out a fix to this problem then mail it back and all that. hopefully someone can come up with some more ideas for me to fix this problem, i know it's kinda out there.

thanks again!

Hello,

I was working on my medion computer this morning, when suddenly it turned off, and it is now refusing to turn back on. I have done what it advised me to do in the computer manual, which was to turn the power supply off, press the on button for ten seconds then turn the power supply back on after five seconds and turn it on.

When it crashed I was using:
Windows Media Centre
Windows Media Player
AOL Vista Ready

I have tried the following to get it to work:

Change which socket I use
Change the cable
Leave it for a while
What the manual said
Unplugging all connections and trying to start it

Does anyone have any other ideas I could try or know what is wrong with it?

Thanks

Answer:Computer won't turn on

HI dan ..

try using a different power supply .. there are other things that you could try first like removing all the power cables to HDD's & CD\DVD's, removing everything but the CPU & CPU FAN and power supply connectors from the motherboard and then try powering on again but I reckon it might be easier to raid one of your other PC's for a similar power supply and see if it boots using that .. and at the same time the other power supply could be checked on a working PC to see if it works .. just take care doing it ..

At first I would turn on my computer and it would shut off about every 30 minutes. If it turned off, I would have to come back and flip the power switch off and wait 10 seconds to turn it back on for it to start up again. Yesterday, I successfully ran a virus scan (up to date definitons-Norton Anti Virus) and no viruses of any sort were present. Of course after the scan completed (3rd time trying for it to successfully finish without shuttingg down) it shut down a few minutes later. I decided to leave the computer off for a while and go upstairs. I tried removing some dust from the fan (I was reading another website that it could be the fan) since it was also making a noise I was unfamiliar with...since my computer is usually silent. Today I went to turn it on, and it will begin to boot up for like 3 seconds and shut off. Any ideas what is wrong or what to do? :( Computers make me so aggrivated! Thank you...

Answer:Computer won't turn on

Sounds to me like a power supply. Does the power supply feel hot to the touch? Touch the case where the power supply is and see if it feels abnormally warm... Don't touch the power supply itself as it could be pretty hot if it is bad... You do not need to open the case to do this experiment. A power supply can be a cheap fix and they are pretty easy to change.

I knew it was because the battery died so I just pugged it in and waited about an hour. I came back to turn it back on, but nothing happened. I left it for a bit longer and still it would not turn on. Any way I can fix this?

Answer:My computer will not turn on?

Remove the battery and AC power cable, leave the battery out and reconnect the power cable, try powering up.

Most laptops tell you if the cable is providing power via a light, check this if your laptop has this feature.

If your laptop doesnt have a light or the light isnt on and it doesnt power up, I'd suggest checking the power adapter on the cable it should have a light on the brick, if it doesnt check the fuse on the plug.

What make and model if your laptop?

When I hook it into power, the light on the motherboard goes on, so I know it's getting power, but when I press the power button, the light goes on on the front of the computer, but the computer doesn't come on. A fan in the back flashes on and off (LED fan) - it looks like it's getting power for a little and then not... But the light on the mobo stays on the whole time... Aaaaggghhh - I've checked every connection, etc.

Well thats encouraging to start with, if your not sure if you did something right, then start from scratch, check everything is seated correctly and that the front panel wires are in their correct place on the board, make sure that the hardware such as video cards are working OK and that the RAM is the right type, make sure any jumpers on the board are in the right place, especially if you have one that resets the BIOS to defaults, some mobo makers leave the jumpers in the reset position.

I have this computer that I'm working on and it won't turn on. I swapped out the PSU and still no luck. I inspected the mobo and saw no blown out capacitors or burns or anything that would suggest a power surge or fried mobo. I have even tried jumping the switch by touching both pins on the mobo together. All I get is a little twitch of the fans starting to spin for a split second and then they quit. It acts as if the mobo is being grounded out, but I suspended the mobo away from the case and it's still doing it. Is the mobo bad or what?

Edit: The motherboard is an Epox EP-8K9A1. AMD Socket A (462).

Answer:Computer won't turn on.

if you have replaced the PSU it sounds like the mobo you dont have to see signs of damage for it to be bad little bit of ESD will do the trick.

Answer:The Computer will not turn on

Hi Allen,
Welcome aboard, Not much to go on but if the problem was off and on before and it does do something now [faint humming] I would say the power is getting to the primary of the powersupply at least and the problem could be in the secondary&rectifier section or the connections between the powersupply and the devices it supplies. Someone will have to open the case and do some checking.Power supplies are not very expensive and a loose connection shouldn't be too hard to find .
Good luck, Bob

I'm building a computer for my parents for christmas to upgrade their archaeic thing they call a computer and i put everything together and it won't start up. Everything is connected right to my knowledge and i think it could be a bad mobo. Its technically my first build although i replaced nearly everything when i customized mine, so i'm not completely ignorant. I thought it might be the PSU so i swapped out the 420 watt psu that came with my old computer that worked fine with the 350 watt psu that came with the case... same results- An interesting note both PSU's make a high pitched hum when the switch is turned on and the cable is connected. No juice tho. I have reseated the cpu twice, all the pins are straight- its my old cpu from my computer that i upgraded and it worked fine the day i took it out. I have checked all the cables to make sure they are secure, and the PSU is set to the proper voltage on the back. I'm stumped- i ordered all parts from newegg and the packaging was fine- no dents and everything was brand new.

Why dont you put all your specs so we might better be able to help.Did you put the motherboard in a new case.If so try to take it out with everything still on the mobo and lay it on some static wrap without the drives hooked up and see if it powers up.It could be grounding out on the case.

make sure the actual cable to your powersupply works, try to use that same cable to power on your monitor (same connections) in any case, try to pop out the CMOS battery(looks like a BIG watch battery onyour mobo) for about 5 minutes to reset your mobo, is nothing else works, you may have a misconfigured connector leading from the actual button TO the mobo, try there.

One thing, there was like a red switch above my power socket on the computer, (where the lead goes into) with 230v and 115V, and I switched it, from 203 to 155, and then it didn't work. That might be the problem, I don't know. But when i switched it back to 203v, still, nothing happened.

The last time I turned it off, I'm pretty sure I just shut it down, like I usually do, instead of putting it on stand-by.
 

Answer:Computer will not turn on!

Not sure where you are located but if in US, and you turned it on after switching that, then you blew out power supply though it sounds like it was blown anyway and is your issue. I hope it was blown before you threw the switch because if not you may have done considerably more damage then that. Personal;ly it is time to take the power supply out and to a shop fopr testing...perhaps the whole tower.

Did you ensure that all power connectors are properly connected?

This is an issue regarding the power supply or motherboard. Since there's no POST beep code (is there?) or anything of the like, there's no other explanation other than these two. You will probably want to RMA it since you just recently purchased it.

Answer:Computer won't turn on

Check that the CPU fan is spinning correctly, as well as any other fans.

You said it was making noise, which is almost always a stuck/dusty fan. If your fans aren't working properly, things overheat and then things don't work. What may have happened is that your power supply fan jammed up and the PSU overheated and died. If the CPU fan isn't spinning, that would mean that the system isn't turning on to prevent damage.

Hi guys, I need help with Packard Bell Windows xp sp3 around 4 years old, cant remember specs sorry. I bought off auction site 1 year ago and after running ok for 2 months it started turning off randomly and then would be fine for another few weeks then we couldn't turn it on at all. Moved house and decided to reconnect again after it being idle for 4 weeks and it worked great but realised it only turned on if we disconnected power supply completely the night before. Run Everest and overheating was not a problem so decided to put new power supply in but did not solve the problem. However a couple of weeks ago my daughter did not pull out plugs when turning off and now it will not turn on at all. From my research online I suspect its mobo but wanted to check with you guys before expanding my skills to replace my first mobo....
 

Answer:And now computer will not turn on

Hello Kiwi, lol.

I assume this is a desktop?

One of the main indicators for a bad motherboard are swelling and or leaking capacitors which look something like:

Blown and Swollen to extreme

Swollen and leaking

Another indicator can be that no "lights" are coming on the mobo when your turn it on.

If you pull it apart further try and get any info of the mobo that you can like "MSI-7060 Ver.1" for example.

If you do think you are going to have to replace it you will need a similar one if you want to recycle all of the other parts.

Hello experts from all around the world !My friends I am in shock: I have a DELL Precision 360 with two Hard Drives of 500 GB and 4 GB of RAM, I never turn it off since I use it a lot at all times. Well my friends last night it happened the unexpectable: after I defragmented my Hard Drives (which I make once per week) and I cleaned my Recycle Bin, I re-started it as I always do. O.K., then it appeared from nowhere a medium size black color rectangle occupying around 1/3 of my screen and the mouse didn't work properly, I mean the arrow was very erratic and I couldn't even to point it out the "Start" buttom; so the only option I had was unplug everything from the wall (actually from my dedicated Sub Station), hoping that any problem will be cleared afger that re-start.But after I connected the PC back to the Substation and I pushed the "on/off" buttom of my console nothing happened, it just did not work at all. So now my friends now I have no PC at all. I am writting this post from the laptop of my daughter.I wonder if the problem has something to happen with the Power Supply ? although I have four 21" CRT monitors I have had never one single problem with it before. Or perhaps the problem has something to do with the battery of the PC ? I don't know what the problem is, so please help me my friends, I am lost without my PC...Thanks in advance for your insights and suggestions. Best, Antonio.

Answer:How can I turn on my computer again please ???

Yes, sounds like PSU. It's under the greatest strain when powering everything up.

Hello everyone!I have a very serious problem, and I need help:I have an (old) computer:Asus p4p800-VMRadeon 9200 se Creative Sound Blaster Audigy SE SB0570The mouse, keyboard and screen, are connected to the computer through a switch (Edimax).The computer had problems before, and tried to fix them. I saw that the connections from the front panel of the computer case to the motherboard were faulty. I rearranged the connections to the motherboard according to the board's original user guide, which I downloaded from the original ASUS website, they are now set well.Having done the connections (and there for also the case speaker, which was set faulty), I began to hear a series of beeps (six) form the BIOS every time I turned the computer on.The beeps were irregular and did not match any of the tables on manufactures site (not uniform and differently sounding beeps (.Other than the beeps, the computer worked great.One problem it did however had, was that it would not return from standby mode (Windows XP). After the computer would go into standby mode, any and all clicks of the mouse or keyboard would not bring it back. The power LED on the front panel would blink, but it would not return from stand by.The only way to restore it was to press the power button; it would cause a computer to reboot (POST, BIOS, etc...)After several attempts, hoping to bring the computer out of standby, I hit reset - nothing happened, then I tried to press the power button - nothing too, a bli...

Answer:Computer won't turn on

if this computer had problems before, which you didn't specify, then it sounds like your power supply is dead, I know you said it looks like it's getting juice but it may only be enough to turn the led on and maybe have a small amount to something else. All your components use different voltages and there is one thing you can try and that is to replace the cmos battery that would be the coin battery on the motherboard that looks like a coin if this is faulty then you computer won't boot or it will be erratic at best. If that doesn't fix it then I would get a power supply you know is good and hook it to your computer and see if it powers up.  The standby issue is probably set in your BIOS you can change that if you can get it to turn on. Try the CMOS battery first you can pop it out and go to the store and match it with another fresh one after you install that try turning on the unit.............gettingthere

Hi. Recently, my younger brother, told me that his computer could not turn on. So, the first thing I did was to check if it was his charger's issue. It seems like it wasn't. Then, I decided to try again with my computer's charger instead on his computer. Well, I noticed something. When I plug my charger into the power outlet, there would be a light to signal power is flowing. And when I plug it into my own computer, it stays on. However, when I plug the charger into my brother's computer, the light vanishes. Is there something wrong with his computer? Thank you !
 

Answer:Computer does not turn on

Sounds like his charger is bad. If your charger works, and his doesn't, it's bad.

The other day I had a very quick power cut in my home. My computer was turned on at the time and obviously when the power cut out the computer went off. When the power came back on I attempted to turn my computer back on with no success. I tried unplugging everything and plugging it back in, and tried turning it on again still with no success. I thought that the fuse might have gone in the plug but the monitor is stiull receiving power, and as this is connected to the power source through the tower I assume the plug is working fine! Does anybody have any ideas what the problem is and how I can fix it? Even if you can give me and idea of what to look for when I take the side off and have a look at my motherboard. I'm at a bit of a loss at the moment. Thanks again everyone. p.s. Im rubbish at knowing what technical info I should include so give me a shout for more info on this.

Answer:Can't Turn Computer On

The power is not reaching the Mother Board. Hence, i guess that means either the power supply of the tower has broken or the Mother Board is damaged. I would first test it by replacing the power supply unit. (you can borrow ....). If you are lucky & it works, you can buy a new power supply unit. Else, u could be in trouble as the MBoard might be damaged.

Answer:computer won't turn on

What brand or model of computer, and how old is it? Give us the information off the label on the back. Desktop or laptop?
Are you good with a screwdriver?
Do you live in a big city, or a small town, because we need to help you find parts or a tech help.

Did you do something different? Like add a new video card, or memory, or other component?
Do any lights come on anywhere? Red, orange, blue. Is the screen totally dark at all times.
Can you get it into a position where you can see the back of the computer?

Usually, the problem is one of these:
Failed or dirty power supply.
Failed or dirty power switch
Failed memory module
Failed video graphics port, if PCI
Failed hard drive, though most will give you something on the screen
Failed or dirty CPU fan.
In some cases, a failed audio card or modem, or usb card in a pci slot, if it fails electrically, will cause everything to stop.
There can be other problems such as a bad CPU or bad motherboard, but they are exceedingly rare.

To begin checking it, it is helpful to look at the back of the machine. At the top of the back is a power supply with a fan. Get somebody to attempt to turn on the power while you watch with a bright light.
If you see the fan blades turn 1/8 turn or up to 3 turns, then stop, that usually means your power supply is bad.
Next, are you sure that wall socket is good? Strange things happen. Plug something else in there to be sure it is working.
You can buy and replace the power supply for $30 to $50. But if... Read more

Sometimes when powering down for the day, after selecting turn off Computer, nothing happens. The screen doesn't freeze but the computer doesn't turn off. I've checked applications with CtlAltDel but nothing is running. I've even tried restart computer but still nothing. The only option is to manually switch off using the power switch. This doesn't happen daily but can be a couple times a week.Will it hurt the system if the PC doesn't power itself down? Any info appreciated. Thank you.

Answer:Can't turn off computer

click here See my post at the bottom of the page. That's what can sometimes happen if the power is cut suddenly before the hard-disks have parked the heads and powered down. Try configuring the power button action to initiate a shutdown if it is not already set like this. You'll know if it isn't because you'll probably have to hold the button in and then the power cuts off.R-click anywhere on the desktop, select properties, screensaver, power and advanced.

Answer:My computer will not turn on

Alright, alright.. this happened to me once before.. although it wasnt exactly the same situation.Im not 100% sure why this happens, but sometimes plugging a device into the USB can cause it to completely lock up (freeze), after wich u can only close it via the reset button on the front, or in extreme cases the power cable on the back.Now, when this happened to me the first time, i thought it was something faulty with Windows so i have it installed again. However the problem came back, somehow the PC would totally freeze every time i plugged in that device. The only thing that does not overlap, is that u say ur PC does not turn on. Mine turned on but then froze again after only a little while.You say that ur PC DOES turn on, but the monitor dosent display anything. Does this mean that the monitor displays the "no signal" colorful hovering box, or is the monitor competely turned off and not even displaying the orange light next to it's power button. As in, is there no difference beetween when its ON or OFF?The PC working but the monitor staying blank (ON, as in the light near the power button is working.. but u DONT get the "no signal" box, as in its just black and nothing else) means that there is probably something wrong with ur graphics card. If there IS "no signal" then its probably not ur graphics card but some bigger problem.Can u answer my questions, and also get another monitor to test with this PC in order to see wich one is fualty?If ur ...

Hi guys, recently I bought an e6600 (got it for Ģ60) and a foxconn 662mx motherboard along with 1gb of some cheapy value ram. Now when plugging everything in it went ok, but it kept turning off, I had a 420w power supply at the time so I wasn't surprised but I noticed I didnt push down the heatsink and fan properly, before I knew this though, I was moving it around to check the little knobs were pushed down, with everything in place, it wouldn't turn on at all.

Now to make things even worse, I foolishly changed the input from the standard 230 odd volts or whatever it is, to the american one, 113 odd. Which made the psu explode. I was shocked and annoyed, but bought another one the next day, probably for the same price, a trust one (probably crap) with 570w. Still no sign on life as before the explosion, the only sign is that the cpu fan apears to move a tiny tiny bit for less than a second before it stops, you hear the psu click into gear for a milisecond too but other than that, no sign of life thanks to the lack of motherboard lighting. No beeps, no going into the post or bios screen, nothing.

I tested my graphics card which survived the pop, but I'm not sure if anything else is alive, I'm really worried it took out my cpu, and I have a feeling it may have taken my motherboard. But the odd thing is that you can see it twitching when trying to turn it on. I've tried everything I can think of, clearing the cmos/bios with the jumper, pulling out t... Read more

When I turn off my computer, the computer turns off as it is supposed to do and then, after several seconds, starts back up again and boots back up. The only way I can stop this process is to trip the switch at the back of the computer.

Answer:Computer won't turn on....

Well, that certaintly maens that something in the power department got tripped. Check all power connections, make sure power supply is switched on, ATX (assuming your board is ATX) power is in, etc. There shouldn't be any other reason why your computer doesn't turn on, if something else was bad, it'd make a big fuss about it with the harmonios tune of your PC speaker.

first of allll, i can't tell you my computer specs at the moment because i can't turn it on. and idk how to find that out without turning it on soooo (my dad built it, ok, i know, cries)

anyway, i will explain to you in detail what was happening that led up to the current problems.

playing computer. all is fine. leave for an hour, come back, and computer is off. i tried turning it on, and the fans and lights turned on for a moment and then turned off. switched outlets, powered on computer, and WOAH it worked again. i got on the internet and chilled for a few minutes, and then it turned off again. tried to turn it back on, no power at all this time. no fans, no lights. this problem persisted, and nothing i did changed that (checked to make sure everything was kosher on the inside (it was)).

so i took it to a repair store and after giving them time to look at it, they called and were like "yeah we have no idea whats wrong with your computer, we're gonna check out your motherboard" and the very next day, "uh, your computer appears to be working fine again!!!!" bring it home, plug it in to regular outlet, and no power. so much for my computer being fine! so we switched the storm/surge breaker thing we were using and this time the computer turned on and seemed fine for a day. today, just now, though, i was playing a game and the my monitor started acting like the computer wasn't on (it went into power save mode). the computer didnt turn ...

Answer:Computer will not turn on

Hi, Anj .

Hopefully, you have XP installed .

<<...and is this fixable for someone with VERY LITTLE computer knowledge...>>

Depends on what the problem is. All due respect to your friend...but there are many situations that don't confine themselves to motherboard/memory choices...which might cause a system not to boot properly.

Sooo...let's pretend that we don't know what the problem is and start from the beginning .

System manufacturer and model?

Nothing at all appeared onscreen?

Desktop or laptop?

Do you have a Microsoft Genuine XP CD?

If desktop...did anyone check the monitor for possible malfunction?

If laptop...did anyone check the panel for functionality...by connected the laptop to a monitor?

The beeps you heard...was that the normal occurrence when you boot the system?
