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

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

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 itself . I had not pushed the power button yet. All of the fans turned on, and the light on the front that turns on if the computer is processing something turned on, but it was not as if the computer was processing something. If the computer is processing something, it flickers and clicks a little. This was just a solid light with no "clicking." I pushed the power button, but it didn't turn blue as it usually does if it turns on. In fact, nothing changed. After about a minute and a half, the entire unit shut down again, and I was not able to get it to do the same thing again. When I tried unplugging it and plugging it in again, I could hear the unit try to start up again for a second, but it would fail again.

Last night, I opened it up to clean out the dust (I figured that could be an issue with overheating despite the fans). I basically took it apart and put it back together again to no avail. I did find one loose wire in the power supply unit. When I plugged it in, it would turn on (lights and fans, but not the computer itself) as it did earlier in the day, but nothing new happened. I noticed that a red light would go on when the computer was "running," but it would go off as soon as everything else turned off. A similar green light would stay on when the computer was plugged in no matter what I did. The power supply unit was no longer hot. The entire unit except for the green light would shut down after about a minute.

This morning, I tried to get it to work again, and it was doing the same thing as it was last night.

I bought it about 3 years ago when it was being phased out, and I was planning on getting a new computer soon anyway, so it's not a big deal if it's too serious. I'd probably try to fix it if I could do so for under $100. Otherwise, I'll probably get a new one. I didn't really have anything important that I hadn't backed up on there, but I'd like to save the hard drive if I could. I'm a novice when it comes to hardware, so I'd be a little nervous about replacing major components (I've installed RAM and that's about it until last night).

So, the three big questions:

1. What's wrong?
2. How can I fix it?
3. Is it worth fixing?

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

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

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.

My computer recently refused to turn on. It had been working perfectly the evening before. I could not smell anything burning or hear anything irregular.

On the advice of Corsair, I bridged a green and black wire on the PSU's 24-pin connector to test whether it was at fault. Upon turning the PSU on with the two wires bridged, the fan began to rotate. So either this is not to blame, or the PSU only partially functions.

I cannot figure out what component is at fault, and replacing parts would be quite an expensive guessing game. The Corsair PSU has a 5 year warranty; however, they require me to mail it to California. Being in Australia, this is quite inconvenient and I would rather fork out for a new one. My motherboard, I assume, is out of warranty.

My specifications are as follows:
Gigabyte P35-DS3P Motherboard
Corsair HX-620 PSU
4xCorsair DDR2 6400C4 (4Gb)
Gigabyte 8800GTS 512Mb (G92)
Antec P182 Tower
Intel E6750 Core2Duo 2.66Ghz
Asus 1814BL 18xDVD+-RW IDE
Western Digital 320G SATAII 7200 rpm HDD(Primary)
Seagate 250Gb SATAII 7200 rpm HDD(Secondary)

I purchased/built it on the 19th of December in 2007

Thank you for any assistance.

I can't turn my computer on. The fans and lights turn on for a second and then turn off. a few seconds later they'll turn back on and then turn back off. I've had this computer for 4+ months now, i built it myself. it recently started doing this but i'd just turn off the PSU (Power Supply Unit) and turn it back on and it woould fix it. now it doesnt fix it anymore. i've re-slotted the RAM (Random Access Memory) and pushed it in firmly, but that hasn't done anything. i've tried different power outlets and pushed everything into the MOBO (Motherboard), i havent messed around with CPU (Processor) because that's just a pain in the a**... i was wondering if there was anything else i could do before having to take it into a local repair shop, lol.

as for my computer specs

CPU (Processor): Fx-6300 AMD
GPU: R9-270x AMD
RAM (Random Access Memory): 8GB Ballistix sport
MOBO (Motherboard): ASRock 970 Extreme3 R2.0
PSU (Power Supply Unit): Corsair X500 w 80+
Case: Rosewill GALAXY


Answer:Fans turn on, lights blink and then turn off/on repeatedly.

First, I would unplug everything that isn't necessary. Everything external except for the keyboard and monitor. Internally, just leave the CPU, RAM and video card installed. See if it turns on. If not, you might try and test the power button. Disconnect the power button from the mobo. If the pin headers allow for it, use the reset button as the power button. If not, you can use a flat head screwdriver to power on the computer (cross the two pins for the power button with the blade of the screwdriver). If you do this, just be very careful. Touch only the power button pins and nothing else! You could easily damage components by touching the screwdriver to the wrong thing.

Some motherboards have a power button right on the board that you can press to power on the computer. I looked at a pic of your board and didn't notice one.

If that doesn't do it, plug the power button back in. You might try and play around with the RAM. I don't know if you have 2 or 4 sticks of RAM, but try and boot the computer with only one stick of RAM at a time. If there's a bad stick, you'll find it through this process of elimination.

If none of the above works, then it might be a bad PSU.

Answer:Fans turn on, lights blink and then turn off/on repeatedly.

You can try a new  RAM stick.What you describe can be: Anything overloads the PSU, or a failing PSU Bad memory in the low region. BIOS  can't run without it. Bad CPU, or heat sink not in placeDisconnect the HDD and the DVD drive. (Power off, of course.)Power on. Does it  show the  BIOS?

Thanks in forward for any help or ideas, but one thing that I could use is howto test to see if you motherboard is damage.

Thanks even more!

Answer:PLEASE HELP, computer won't turn on, fans come on and lights blink

Have you checked that your fans are spinning up? Is the heatsink sitting flush with the CPU? Have you made any changes to your hardware on the mobo?

I started lagging while playing player unknown battlegrounds. So i closed the game and restarted the computer. I then noticed the entire system was lagging. System sounds and everything. Took 5min to open taskmanager.
I then restarted again and after that it would just turn off 1min after i start it. Only thing that comes on is fans and lights etc.
I changed to different ram slots just to try. And it starts and does not turn off now. But the screens dont come on, and everything connected to USB dont come on. Ant idea What the issue can be?

I have a Toshiba Satellite (about 2 years old) and for the life of me, I can't figure out what' s going on.

Here's what I do know:

I used a multimeter to test the voltage of the power port on the connector that plugs into the motherboard. I'm getting 19volts which is what it's supposed to be at.

I have replaced the bios battery - nothing

I have held down the power for 60 seconds with it unplugged - nothing

I've tried running on a/c power only - nothing

Possibly the most confusing thing - I was fiddling with the network adapter (the internal pci one - not the usb kind) because after tearing it apart and putting it back together so many times I was trying literally everything - I switched out the network card. (I realize what little sense this makes) but it turned on. For only about 15-20 seconds but it turned on. 3 times. Then died before it ever fully loaded windows.

I assume there is something on the motherboard around the network card area that I touched that made this happen. But I can't for the life of me figure out what. It has been dead as a doornail for months. And something happened when I touched and swapped out the network card.

*total confusion*

Answer:Laptop won't turn on, no lights, no fans.

Does a charging light illuminate when you plug in the power brick to show it's providing power to charge the battery?I
If you wiggle the connector from the power brick to the laptop, does the charging light flicker?

Have you attempted to see if it boots up without the wireless card?

Hi,My original problem was my computer randomly shutting down without any error messages or anything like that, as well as not being able to turn it back on until after a while, seems like the longer I leave it turned off, the more time I get to leave it turned on before automatically turning off. Anyways so I decided to open up my computer and take out the heatsink and everything else out, and clean the dust off. After fully dusting off the computer I plugged everything back in and now the fans, and lights turn on, and the power supply fan slowly spins before finally spinning after a while. I get no display or any usb mouse light. I tried taking out the CMOS battery and then putting it back in, Also I get no beep when I take out the ram. I tried taking out the video card and plugging VGA unto motherboard. Also the hardrive, it spins so dont think its a hard drive issue. When I took out the cpu it broke the thermal paste off, so I was wondering if that has to do with anything?Also I am thinking if it might be the power supply and me needing more then 500 watts.

Answer:No Display-Fans and lights turn on

A quick read of your post indicates that you did NOT damage the power supply. You did something when you removed the heat sink. Check your work, but before you do anything, get some thermal paste. It does not cost much and is required when you take off the heat sink.

Hi, I would firstly like to apologize for not being able to update my user CP or tell you what my CPU/Mobo is. I can't get my computer to turn on and can't access the info.

This happened while I was trying to reset everything on my computer (because there was a problem with my NIC). I unplugged everything and replugged them into their respective places, and now I can't seem to turn my computer on. Everything was working fine (except the NIC) prior to my resetting. Now the problem is when I turn on the power, there would be a small delay before it would turn on, and when it does turn on, the lights in front of the computer (for the on switch) flash, the flashing intervals are synchronized with the rate the CPU fan turns on and off. The case fan is running constantly however and it is blowing out cool air. I have done some searching on the forums, and I have heard that it was because I unplugged the 12-20 wire that connects the power button (in the front) to the CPU. I unplugged this wire and the fans still turn on and off, except the front LED's can't flash. If anyone can help me, that would be most appreciated.

Answer:Lights flash, fans turn on and off, comp remains off.

You gotta do some more diagnostics.
But before I'll start listing them, I have one question:
Before you've removed components from your computer did you un-plug it from AC outlet? Cause if you didn't you may've damaged motherboard or any other component for that matter. I know it sounds silly but I'm just making sure.
Anyway, do as follows:
Unplug the power. Open the case and re-sit you memory modules and if you have to re-sit your CPU chip. Re-sit all your add-on cards (sound, video etc.) Make sure you re-install the CPU heatsink properly. Make sure that all cards and modules are snug and properly sitted in the motherboard.
Note! Dont' ever operate your CPU without properly installed heatsink, ever!
Plug it back in and the try to boot. If it's still no go:
Unplug it. Pull all the cards out except for the video card. Disconnect all your drives: hard drives, cd/dvd-rom/rw drives, floppy drive(s) etc. Actually disconnect everything from you motherboard except for: CPU, 1 memory module and video card (and of course power supply - make sure the 12V+ cpu plug is in the motherboard!). Plug in and power on. See what happens. If it's still no go move the memory module to a different slot; power on; still no go - pull the video card out: plug-in power on; still no go:
- Your power supply, motherboard, memory module or CPU has gone bad - you gotta swap them out with differnt component to test if this fixes the problem; star... Read more

Answer:Fans automatically turn on ?

To the best of my knowledge, this is a built in feature of computers to prevent themselves from overheating. In hot weather, even if the computer is off, it sometimes runs the fan for safety purposes. It's nothing to worry about.

Hi. I just built a new computer, and it has 4 case fans, with lights, and 2 lighted fans on the power supply. This is in my room, and awfully bright if I leave on. I've looked into fan speed controllers, but was wondering, is there a way to have them automatically turn off when I put my computer into sleep mode? I have a clear acryllic case, so thats my biggest problem right there. Thanks.

Answer:Can I have fans turn off automatically in sleep

If by sleep you mean standby, then you should be able to do that. In the bios, you should be able to select the suspend mode. Chose s3 rather than s1. s1 leaves the fans on, s3 turns them off.

Are you sure when you were working on the machine that you didn't unplug any internal cabling inadvertently? It's definitely worth re-opening the case and taking a look.

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.

One night, a couple months ago, I was trying to play a game with a friend when my computer just turned off. It wouldn't turn back on. The next day I was able to get it to come back on and it had some boot message, but I didn't have time to read it before it booted. It was on but wouldn't charge. I turned it off to conserve battery a couple more times before it was permanently dead.I have tried hard reset, but I get absolutely no reaction from my computer.I have replace the internal DC power adapter, but the computer stills doesn't respond (also retried hard reset). So the motherboard should be getting power, but my computer doesn't turn on, charge, or blink. It worked initially after dying, so why doesn't it work now?What kind of options do I have? I would love to send it in to HP to repair (as long as it doesn't cost more than $400), but I have had any luck contacting HP support yet.My computer is out of warranty.

Nothing else. That's the kind of thing I get if I'm lucky enough to have it recognize anything there at all, lately. Mostly, it doesn't recognize them at all anymore. As a matter of fact, part of its erratic behavior is that half the time, if there's a cd or dvd in the drive when the computer is turned on, it gets stuck on startup before the user account screen pops up and won't go anywhere unless I open the tray up.

Hi PARTH511722,
What is the exact system model?
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible? Could you try powering on with another battery?
Remove the memory and disconnect the HDD and try powering on the system with adapter only / battery only and check.
Does the adapter led stay on and stable or does it go off when connected to the system?
If the adapter led is stable when connected to the system and there are no signs of power, then the motherboard is suspected faulty.
Also, please click my DELL-username and write me a private conversation with the service tag and your Name for case records.
Let us know if you have any other queries.

Hi guys, this is my very first forum post ever in my life and I hope I get super help.So there I was working on my computer one day. I was downloading a youtube video with a program that has scheduled shutdown computer option upon download completion. I turned that on and turned off my monitor. After about 1-2 mins I noticed the power and HDD indicator lights in front of the CPU casing is turned off so I thought for some reason my pc probably turned off. I tried turning it on by pressing the power button and at the same time turned my monitor on. It turned on with a light-brown colored background so I quickly hit restart but then it won't turn on. I plugged by USB in hoping it would try to boot from the USB (my bios settings primary boot is set to removable devices). Then I pressed the power button again but THIS TIME I noticed that a very bad wire-burning type smell is coming out so I instantly turned EVERYTHING off. Later I opened my CPU casing and tried smelling the devices and found that probably the smell is coming from my second (and newer) hard disk that is about 10 months old. So, finding no hope and ideas I threw myself to's forum from my school laptop...please anyone help me out ASAP!Note that when I still try to turn my the pc on the power supply fan, the ethernet lights and even the DVD-rom drive works; so I am totally confused!My pc is  Intel Core2duo, 2GB ram/memory, 256 internal video memory, primary hard-disk=160gb and secondary...

Answer:CPU/Power Supply fans work but indicator light in front doesn't turn on.

Minimal boot is where I'd start. If motherboard has integrated video use that, disconnect all drives, and just have the motherboard set up with 1 ram stick, and try to boot. If you get it to boot then shut it down and add 1 component and boot up again if no boot then you found the cause if it boots then move to next component to add and repeat. If no boot on minimal boot, then swap single Ram stick with another if you had more than 1 stick. If still no minimal boot swap power supply. If still no minimal boot its something local to motherboard. Unistall CPU and check for damage and reinstall it, apply thermal compound and heatsink and try another boot. If still no boot, I'd buy or use a different motherboard unless you have a POST card to work with and want to troubleshoot deeper.Cooked component smell is not a good thing, if you can localize the smell and find burned traces or parts that would be a help in determining if this can be saved or if you need to start a new build. I have only seen one hard drive smoke before and that was my friend way back when SATA drives first came out and it had a P connection as well as SATA power. He hooked up both and cooked it. On a small warning in the box it warns not to plug power to both. I'd doubt if your drive is one of these drives given that you mentioned that it is 10 months old.

I recently had to take my computer in to be fixed only to find out my GPU was fried but the guy there was going to way overcharge me to install a new GPU so I decided to do it myself as I have done so before. So I got a new video card, I installed it, I clicked the power button and the cpu fan spins for half a second and then nothing. I called the computer guy and he said when he had it there it was working fine with other video cards and would start up fine. So now I don't want to pay him yet again to try to figure out why it won't even turn on. I've try reseating the memory, reseating the GPU. The lights on the motherboard and the lights for the power inputs to my GPU are on and yet it still won't start. I don't know what to do next. I hope one of you fine people here can help

My specs in case it matters:
CPU: AMD FX-8350
PSU: 750W

Answer:Computer won't turn on but motherboard and GPU lights are on

What's the brand name and complete model number and revision number of the motherboard?

What's the brand name and complete model number of the 750W power supply?


Your "computer guy" doesn't sound like he's very reliable.

Was troubleshooting a computer that won't start

Computer worked perfectly fine, underwent an update, and inexplicably crashed. Trying to turn it on won't so much as hint at a flicker of any light whatsoever on a motherboard, or screen, or even make a sound from a fan, or turn a fan on, etc. Absolutely dead.

Tried a brand new PSU to no avail. Disconnected previous one, and connected new one exactly as the previous one had been connected. Flipped the switch in the back of the new PSU to 'On', and tried the 'On' button on the case. No peripherals were attached whatsoever at any time. No joy.

Under these circumstances, would the problem most likely lie in a tossed-out motherboard, or CPU, and why? I imagine these could be the only two culprits, unless a bad CPU fan could be a candidate? A fun note: this is a refurbished computer (I wonder why those are a bad idea?)

*Added* It was the windows 8.1 update that the crash happened under (but not necessarily caused by), and the computer is a Gateway DX4870 that had 8 installed already. This should be it: - Refurbished: Gateway DX Series DX4870-UB2B (DT.GEEAA.002) Desktop PC Intel Core i3 3240 (3.40GHz) 6GB DDR3 1TB HDD Capacity Windows 8 64-Bit

My computer just recently crashed while I was playing a DVD. It had been running fine for about 1.5 years, except for the occasional BSoD (kernel inpage error) in the past couple of months after I had been playing Wolfenstein Enemy Territory for extended periods of time. This time, however, it wasn't a kernel inpage error, but something else. I didn't catch it, as it flashed pretty quickly. My computer proceeded to reboot, but then it froze. I turned the computer off, and when I tried turning it back on again, nothing happened. No lights, nothing. BUT the CPU fan and the case fans were still running, and the only way I could get these to stop was to unplug the power.

I'm about to go borrow a stick of ram from a friend to see if that's the problem. Does anyone have any other ideas as to what could be wrong? Thanks in advance.

So I built a budget gaming computer one and a half months ago and everything was working fine until 2 days ago. Initially, the computer ran Civ V and Shogun 2 just fine.

AMD X4 760K
MSI A78M-E35 FM2+
EVGA 896-P3-1264-A3 GeForce GTX 260
Kingston HyperX 8GB 240-Pin DDR3
CORSAIR CX series CX500 500W
Windows 7 Pro x64

But 2 days ago, I noticed while I was playing Civ V, the computer would suddenly reset to the bios screen and restart. This happened when I played any graphically demanding game, but not during normal use.

1 day ago, the computer started resetting itself to the bios screen during regular web browsing (no gaming), and when it was idling.

Today, I took the graphics card out and it booted (but I couldn't tell what was going on, because I don't have integrated graphics). I put the graphics card back in and it didn't turn on. I took the graphics card back out, and the computer still won't turn on. Now when I press the power button, the fans turn on and off, but the computer doesn't boot. No beeping.

My guess here is the power supply went bad. But I'm more worried if the motherboard is fried. Is there a way I can test? I don't have another computer (aside from this linux laptop I am on right now), or any spare PC parts. What can I do?

Hey guys. I'm just trying to help out a friend. I think I know what the problem is but I just wanted to get a second opinion, and maybe a third and a fourth. I think the problem is the power supply but before I send this poor college student out to buy a new one I just wanted to make sure.

Any way, she has an old Packard Bell running with a Pentium 200MMX . It's an AT power supply. What happened is she turns the machine on and the power light blinks on, the cpu fan spins for about a half sec. and then nothing. No power, no beep codes. So, she brought it over, I plugged my cord into it and the same problem. I checked all connections in the computer and everything looks ok. Then, I disconnected the power supply from the motherboard and then connected it. Plugged it in with the same cord and the machine turned on with no problem. Booted up to Windows and everything. Even let it run and checked out some basic programs to make sure nothing happened. I thought it was just a funny glitch (keep in mind that no one has ever opened this machine since it was purchased) so I packed it up and sent her home with a extra power cord just in case. Of course I got a call and she was having the same problem. So, what's the verdict hardware guru's, power supply or serious problem?

A few months ago i built a system through a popular computer company, ibuypower, and was initially pleased with the performance of my PC. I was then forced to take a few months away from the system due to work, during which it was stored in a safe dry location. Upon returning the system had the issue stated in the title. I have replaced the power supply with a far better one (went from 450w to a 700w) and the same issue peristed with the new power supply, which works with the tester it was shipped with. I've read about it possibly being the Ram, so i have ordered a 16gb ddr3 ram upgrade (2x - 8gb sticks) and they should be here within a week. I also read that it may be the CMOS battery but those are unable to be shipped through the mail so im having trouble tracking those down here in Japan. If somone could help me figure this out i would greatly appreciate it. I've cleaned and tested everything i can and i can't find an issue other than it physically wont function. Also, in case anyone was wondering this thread was written from my laptop, not the PC.

I'm definitely not an expert but I have general knowlege from building a couple systems. My current system is the following (I apologize if some details are left out, I'm currently at work)

OS: Windows XP
Chip: Intel P4
MB: Asus P4P800 (865 PE)
RAM: I forget - 2 sticks of Kingston = 1gb
Video: Nvidia 5600 AGP (running 2 monitors)
PSU: Generic from Fry's 400w

I was listening to some streaming music and left the room for a couple minutes and came back my computer had shut down. When I got closer I could hear the system trying to boot, the fans would spin but it would shut down every 2-3 seconds. I switched the power off from the PSU.

I bought a replacement 500w PSU from Fry's figuring it went bad. I installed the new PSU but the system would not boot. THe fans would come on and a light on the MB was on but nothing. My monitors weren't receiving a signal either.

I then thought maybe it was the video card and went and bought a Nvidia 6800 AGP but still nothing.

I read online and tried a few other things:
- Removed the onboard battery on the MB and reseting the CMOS using jumpers
- Removed all PCI components including video card and tried booting and then installing only the video card and rebooting.
- Removed one stick of RAM
- Removed hard drives

At this point I think it might be the MB or just another bad power supply. Any other suggestions?

Thanks in advance.

Problem description:
I built my computer in January 2008. When it is turned on, there is a blue light on the front panel next to the power button that burns steadily (Case is from Cooler Master).

Most nights I turn my computer off when I go to bed. Sometimes though I don't and leave it running all night. The longest I've ever had it on non-stop is probably about 72 hours. After about 30 minutes my monitor goes on standby and switches off. It wakes up and returns to desktop when I press a button or move the mouse.

Last night I kept it on. It had been off the previous night so it was probably now running for about 20 hours. When I returned to it this morning I moved the mouse and pressed some buttons and nothing happened.

I tried turning the monitor on and off but it remained on standby.
So I decided to restart the computer. I pressed the restart button on the front panel but nothing happened. I held down the main power button for 20 seconds and nothing happened. At this point I noticed that the blue light was flashing instead of steadily burning.
The only way I could turn it off was by turning off the psu power button at the back.

I can not get the POST screen to appear. In summary, I can not get my computer to boot up when I turn it on. I can only turn it off by disconnecting the power.

When I press the power button, the blue light flashes; and the numlock, capslock and third light on my keyboard flash as well. The monitor does not turn on and there are no beep... Read more

Hello Forum,

Summary: Weird burning smell for 2 or 3 boots --> Doesn't turn on, no sounds or lights from comp --> replaced power supply --> worked for a few boots --> back to completely nonresponsive state 15 mins later (details follow....)

I do not know the system specs and I can't find them out without posting this issue at this time. It may not be that necessary to know the details but I can find out soon if necessary. Let's just say it is NOT a new computer - the motherboard is large - I could tell you the model in a later post - the processor is 1.x GHz, something like 512 MB RAM, I have 2 HDs. I am running Win XP.

Old Power supply: Was pretty old, up to 10 years old but maybe a few years younger (300 or 350 W). I haven't seen the computer much for 3 years since I started using and it was upgraded in the meantime.

One day I turned on my computer and shortly afterwards the room started smelling like burning metal/rubber or something acridly foul. Opened the case and nothing seemed to be boiling or noticeably hot, though I didn't really touch around. The only thing that was reasonably warm was the P/S. I thought I noticed the smell coming from it but it was only slightly smellier in that area, at most. Didn't add anything special or change anything in comp recently beforehand. Played loud music on in the night before but the speakers have their own power supply.

So I decided to replace the P/S - I purchased an hec HP485D 485W ... Read more

It's extremely likey that when your PSU blew it damaged your mobo as well. If you have removed and replaced everything else and nothing works then it's either your mobo or cpu. In this case it's likely your mobo.

My problem is actually similar to the following:
This thread however had no responses.

I know a little more about my problem and hope it can be solved here.. Sorry for making this post so long, but this problem is a real bugger and I'm giving all the info I can.

The problem: When the computer doesn't start
When I plug in the computer, pressing the power button does nothing. This problem is aggravated in winters (weird but true) and when the D-Link ethernet card is plugged in (whichever slot).

When it does start:
In summers, I leave it powered for sometimes, say 20 min.
Gradually the power light on cabinet starts blinking rapidly (on pressing the power button).. a little later the HDD lights also start blinking. The CPU fan turns in jerks and in sync with these lights. A little later, the computer boots normally and works fine after that.
Also, operating it increases the temperature, and subsequently the computer can be made to start without problems.. till it cools down or I disconnect mains.

How I have to start it when it doesn't:
In winters, the above procedure doesn't work. Then I can try one of two things (I usually avoid turning the comp at all, use my laptop instead, since I don't like either method)
I can point a hairdryer from a safe distance at the motherboard, and keep the power button pressed. It starts in a little while.
OR, this is possibly a worse method..... Read more

Answer:Computer startup problem: power light flickers, fans turn in jerks

Have you replaced the BIOS battery? after 5 years its is most likely dead or nearly dead by now. Get your multimeter on it and check it's voltage (my money is on this)
Have you tested the CPU fan to see if it spins up OK, test on another PC if you have one?
Have you tried booting up to just the POST with NO drives connected with power?
Tried another PSU? Does this PSU work OK in another PC?

Whenever i turn on my computer, it loads the desktop, then a few seconds after it has loaded, it automatically restarts

This happens in a repeated cycle

However, if i make it so the computer has a lot to load early on, such as clicking on firefox or media player a few times, it seems to load these programs, obviously very slowly, and then the computer does not restart itself. IS this something to do with the computer being too busy to "think" about restarting?

I searched the forums, and google, but none of the problems i found seemed to restart in the same circumstances, and they didnt say anything about loading programs early on

I have turned off "auto restart on system failiure", as this seems to be common in the restarting posts, but not tested what happens apon turning the computer on yet.
Also, if this is the problem, then i don't like the idea that my system is failing every time i turn it on.

I have a Lenovo H320 desktop that I bought about a month ago. I'm trying to get it to turn on automatically every morning. In the bios there is a "Wake on Alarm" under "Power". I can set a wake date and the computer will turn on as expected. However, I don't see any way to get it to turn on every day at a set time. It will only allow me to set on specific wake date, which works, but then I have to go in each day and set it for the next day. I've used this feature before with computers and they usually have an "Every day" setting where you put in the specific date, but this computer doesn't seem to have that. I'm thinking maybe there is some special characters I can put in the date fields that will make it wake up every day. I've seem bios screens that don't have this feature at all and I've seem them to that, but when they do they always have an "Every day" setting, which make sense because there isn't much use in setting it to wake up just one time on one specific day. Does anyone know if there is a way to set the "Wake on Alarm" to wake every day? I sure don't see it.

I've got a Dell Inspiron 6000 laptop, it's about 4-5 years old. I'm not very tech savvy.

A weird thing started happening recently:

Whenever the computer shuts down (Standby, hibernate, or full shut down), either b/c I power it down or just b/c I close the lid, the computer refuses to turn on again.

When I press the power button, the fan starts up, the power light comes on, the caps lock light blinks 9 times and then it turns off again. Happens regardless whether the laptop is plugged in or on battery.

I have discovered that I can get the computer to start up by holding down the "play/pause" button bellow the touchpad and pressing a bunch of keys on the keyboard simultaneously. This causes the computer to turn on and opens a program called Dell Media Experience (which I've only used occassionally before). But this "solution" is not reliable and seems to be getting less and less effective(the first time, I just pressed the button, since then I've had no success unless I also hammer the keyboard a bit).

At this point, I'm afraid to let my laptop sleep or turn off for fear that it will never turn back on.

Anyone have any idea what the problem is? PSU? Motherboard? Something easy to fix that a non-techie like myself is just unaware of?

Plz let me know ASAP.

Ok the specs are in my sig...

This computer is almost 2 years old and I am seeing some signs of it being dead *lol*

running windows 7 (i think not important because it doesnt even go to the bios screen)

Symptoms included:
1. In the last month, when I turn on my computer, it doesn't turn on immediately and go to windows, but instead, it restarts for at least 5 times and then it goes to a "good state"... (take note that it does not go to the BIOS screen in the 1st 5 restarts) after that can I only use my computer, im not restarting because it i restart, it happens again...

2. Now, when I turn on my computer, it doesnt go to the BIOS and restarts over and over again... no display, no hard drive activity (referring to the light)...

I reseated the video card, the 2 memory cards, then I tried to fire it up, but to no avail, it gets the same thing... is my mobo broken? or is it another hardware?

sorry for my english, im not good at it...

please help me techies out there! any information will be greatly appreciated...

Answer:Computer doesn't turn on

It's probably a bad component on the motherboard.

If I were you, and I really wanted to fix that motherboard, I would start by checking the capacitors and replacing any that look even slightly off.
Then I would reflow every solder point on the board that looks discolored/dirty/not super shiny.

After that, I would pour some liquid rosin flux over the Northbridge, and southbridge, make sure that it has a nice coat on the underside, and then heat it up with a pen torch or reflow station.

This will most likely fix your issue, but it's sort of hard to guess at what the problem is by your description.

If a computer won't boot, and you've tested each ram stick individually as well as together, then the problem is likely failing hardware on the board itself. You can pay someone to perform this maintenance on the board for around $150, but it's cheaper just to buy a new motherboard.
Of course I don't know because I'm not looking at the motherboard. It could just be something simple. I would suspect that during the first 5 reboots one of the capacitors isn't holding a correct charge, and it takes a few restarts to get it to hold the correct charge. This is a guess though, I don't know.

When I turn off my computer the power supply doesn?t seem to turn off, the fans are still on and so are the LEDs. Windows shuts down and the HD stops too. The only way to turn it off is to press the button on the back. This does not really bother me but I would like it to totally turn off when I say it to and not have to press other buttons. Is it bad that this is happening and/or is my PSU shot? All of my voltages monitors show the same thing as before, nothing has changed.

I need serious help. I got to school online and am in a really hard class. Now, my computer is flaking out on me. I like to turn my computer off when I am not using it because periodically the computer sounds loud like I am doing twenty things at once when I am not even using it. Then my computer gets quiet again. I have XP Home Edition and it doesn't turn all the way on sometimes. In these instances, all the lights that are supposed to be lit on the tower are, but the monitor doesn't turn on. I have to hold the power button in until the tower turns off, I wait about thirty seconds then turn on the power again. It is like Russian Roulette, sometimes it works, sometimes I have to do this again. It has gotten slower too, my computer is so freakin slow, and it just froze on me for a moment. I am not sure this next piece of information will have anything to do with this but last week I had ran and downloaded the MS Essentials program for viruses and spywares. It said I had Win32/Induc.A, and it said it was a virus. All the files listed below it I deleted even from recycle bin so I thought it was gone. I looked up information about the Induc.A and it said it attaches to Delphi files if you have them and copy files and rename them as well, which I did a search and found no delphi files. Then the MS Support Page said that if none, it will just bounce around your system in a richochet style.I will check in later, to see if I been hooked. Thank you.

Ok here is the problem we been having. It seems that we have problems with our breakers going on and off constanlty but this time it really affected our pc. Our stupid landlord didn't pay the electric bill so our power was shut off durring the night. once it was back on we tried starting our computer back on an guess what nothing happened.

So i checked things out. first i checked the reset switch and we bought a new one of those, new power cord for the power supply, nope that wasn't it.

There are two color light bulbs by the reset switch the green one comes on when the computer is working. its not turning on and the yellow remains on tho so i figured its still getting power but maybe not from the power supply but from the battery since its a pretty big battery. But the fan isn't running, neither are the drives and other things so i think it is in the power supply. Do you think it might be the mobo tho? This computer is only two years old and it has a celleron proccessor and so i was also wondering could it be the processor too?

So here is the questions, what do i replace first? The power supply , proccessor, ram, mobo or just buy a new comp?

Just to let you know yes its plugged in and its turned on and the monitor is turned on also.

Answer:Computer doesn't turn on

First thing you should buy is a battery backup. Computers are very senstive to electrical problems, using a battery backup and a good quality powersupply will save you possibly thousands of dollars.

Most of these issues I've run into have a sort of chain reaction effect on the destruction of the PC. In all likelyhood, your powersupply is fried. If it was a good quality powersupply then that should be the extent of the damage, however if it didn't fail correctly then your motherboard could also be damaged. Depending on the quality of your motherboard, any various components of you PC could also then be damaged.

So giving that I understand your situation correctly, I'd first buy a battery backup (I prefer APC but Belkins are decent), then I'd buy a Powersupply (not a cheapo 350w Powmax, look for a good name like Enermax, Antec, Fortron, OCZ, or Seasonic) then see if your PC will start up. If its a no go then you need to replace the motherboard (at which point a system upgrade becomes an entertaining idea).

If at all possible try testing the components of your PC in another working computer so that you can devise what's good and what isn't.

But regardless, get a Battery backup.

First of all, sorry that my first post is for help but the problem is how I found the forum.Basically, one morning I turned on the computer and was just doing my daily things when all of a sudden the computer turned itself off, it was very sudden, no signs of any problems or anything. Now if I try to turn it on, the power button gets pressed like any other useless button and does nothing. Makes a little click sound like always, and the computer does not turn on.My belief is that this is harddrive related; however I am not entire certain if that is what the problem was. My harddrive is 40GB Western Digital harddrive, and I'm currently looking for the box to give you all more information but can't seem to find it, I will continue looking however.I tried turning off the powerbar, cooling the area around my mid-tower case, and cooling the case itself down, letting the computer rest for 24 hours, and then turning it on, but same problem, pressed the button, it didn't turn on. If this isn't a harddrive problem, anyone know what it could be? If you need information on any other parts of my computer and whatnot, please ask I'll be more than happy to provide you with the information.  Also, if the harddrive did die out on me, is there anyway of fixing it,I will respond ASAP if there are any other questions.THANK YOU! ... in advance.

Answer:Computer doesn't turn on

It could be a power supply, possibly the hard drive, maybe even something else.It seems that to solve this mystery there needs to be a little "operation".  If you've got the know-how to open up the case (which I am NOT advocating) UNLESS you have experience, I"d recommend taking the system to a knowledgeable computer repair person.  Alan <><

Answer:Computer doesn't turn off

If your computer does not turn off the power when doing a shutdown,
you may need to edit the registry.

Start Regedit
Go to HKEY_CURRENT_USER\Control Panel\Desktop
Edit the key PowerOffActive and give it a value of 1
You can do the same in HKEY_USERS\.DEFAULT\Control Panel\Desktop
You can go here:

Hello everyone!! (I think I'm the only one here though on a Saturday night )

Anyway, I've been reading through the forum to see if I could find some answers to my problem with my HP and the closest one is "Old School" dated September 1, 2006. So, I've noted some of the answers and I'm going to try some things (that apply) tonight with my computer.

However, the initial problem started when I began to notice my computer slowing down, so I decided to remove some programs, files that I no longer needed. Afterwards, it didn't seem like it help any at all. A few days after that I began to get errors saying the memory was low and so I decided to completely start all over, going back to when I bought the computer new. However, when I attempted to do this it wouldn't let me saying the memory was low or not enough memory. Next thing I knew my computer completely crashed and I haven't been able to get it back on. Here are some of the things that are coming up when I try to start it.

Okay, so my desktop computer used to be on all the time and then all of a sudden it went off and it just simply is NOT turning on. Pressing the button to turn it on does absolutely nothing. I've tried leaving it unplugged for a week, and it still didn't work. There is a light on the motherboard so I know that the motherboard does have power but I can't figure out what's wrong. Can someone please help me turn this pc on?

Answer:Computer doesn't turn on

The problem sounds like the power supply, if not that, then the motherboard. A good way to narrow the problem down, would be to swap a known working power supply, and see if the computer boots up. If it doesn't, there is a problem with the motherboard (considering all wires and cord are connected properly and there are no other power issues such as AC outlet, surge protector, bad PSU power cable etc.)

8gb corsair ram

I have hooked everything up, as according to the manual, I did hook up the 8pin and the 24pin to the motherboard from the power supply, ram and cpu is installed properly, everything is wired correctly according to the manual

-usb3.0 goes into the usb3.0 port
- port for the fan goes into one molex connector

- 24pin and 8 pin from the power supply is hooked up right.

Welcome to the forum

Remove all add in cards, hard drives, disk drives, use one stick of memory in dimm0 then switch to dimm 1, then switch to a different stick. Since nothing happens make sure you have your power switch connected properly and that it works, double check the front header diagram for the power switch pins and if you get nothing at all short the two pins with a screwdriver to see if it fires up. Your video card will also require one 8pin pci-e power connector and one 6pin pci-e power connector so check those also.

I have a Dell Dimension 8400 with Windows XP Pro on it. It's only a year and a few months old.

Anyway, a few months ago, I turned on the computer and instead of loading properly, it beeped and nothing showed up on my computer screen. And all I could hear after the beeping was the fan, which I noticed to be abnormal since the machine makes its usual running sounds. So, I opened up the computer and saw that one of the metal strips that covers an unused drive space was loose, so I tightened it back into place, closed up the computer and when I turned it on, all was well.

Now, just a few days ago, the same thing happened except nothing I did could make my computer turn back on. I tightened the metal strips, drives, checked all plugs, etc only to find out that whenever I pressed the power button the green light goes on, the beeping happens, but the computer will not turn on and function. All I still hear is the fan on inside the computer.
Please help.

Answer:my computer beeps and doesn't turn on, help!

Does the beeping stop after a certain number of beeps each time? If so, count the beeps and refer to the online help available through the PC manufacturer. It's possible the movement when you opened it up caused the machine to work again and was not related to the metal strip. (possible). If you have more than one ram module, try each one separately. This may single out a bad one. If there is any way that you can borrow a friend's ram memory module(s) try different ram. Almost every time I've had the beeping problem, it has been ram related.

The computer loads to the xp home logo, sounds like its gonna shut down, then starts all over again (reboots and continues this cycle)

It's running Windows XP Home.

It was just loaded with a bunch of Windows updates, probably a years worth I'd guess. Also, a virus scan was run and found a bunch of trojans, but this was h0ours before windows update and the computer shut down / restarted properly after the virus scan was done.

Or, in other words. The virus scsan ran, tried to remove a bunch of trojans (but I guess it didn't remove them properly because it keeps getting a bunch of messages that the Trojan horse is still on it). After that, the computer restarted properly. Then, Wijnodws UPdate went, installed a bunch of things, and now it wont start properly

I have been searching everywhere for an answer to my problem and have yet to find something. What happens is, after using my computer for extended periods of time (6hrs+) if I for some reason, shut down the computer (Or say the power cord gets yanked out) it will simply not turn back on immediately.
I click the power button to turn it back on, and for a split second the fans, etc, spin and then just cut out and everything is dead. If I click the power button on a second time, nothing even starts to work for that split second; its just completely dead. Now, if I take the power cord out, wait 10 secs, and then put it back in and power it on, I get the same split second power up, and then it goes dead.
The only way I get it back on again, is to leave the power cord out, wait around 10-15 mins, reconnect the power cord, and it works perfectly.
This problem only seems to occur when the computer is "hot", like I said after being on for a fair while, and immediately turning it back on. If I go to use it in the morning after being off all night, I never get this.
