I have a problem with an older computer (98-99) I turn it on, and it starts to turn on, and then as soon as it starts to load a little bit it turns off, The moniter stays on though. I have Tried putting in the recovery disk but the computer turns off before I get to start formatting, does anyone know what it could be? I have tried plugging it in different outlets and nothing changes.. Is it the power supply?

It could be, but we need more information. How far does it get? What's the last message that you see before shutdown? Is it consistent?

You should also check around the back of the unit and see if the power supply fan is spinning normally (it's usually visible). If not (a common problem due to binding bearings or being clogged with dust), the PS is probably baked to death (long-term overheating) and will have to be replaced.

It gets to where the things on startup are loading, you can see the desktop and move the mouse, then it shuts off. Now if I push the button again, it doesnt work, unless i go down on the ground, turn OFF the power strip, wait 5 seconds, then turn it back on, and the process will happen again. It seems as if the fan is spinning like it should

That's a Windows problem you have there, then, most likely. It doesn't sound like a hardware problem at all.


Somehow, your drivers have been corrupted, or some software is trying to load which is causing Windows to have a 'seizure'. You could spend ages trying to track it down, or you could format the hard drive and install Windows again. you'd lose all your data if you did that.

Try booting Windows in 'Safe Mode' (by pressing the <F8> key while Windows is first loading) and see if it runs that way. If so, it may be recoverable.

You don't even get to the startup? Perhaps your video card blew it...

After this further information I'd believe it's a hardware problem as well. I'd initially thought it to be a software one, as you'd mentioned it had loaded far enough for you to view the Desktop and then froze.

You've mentioned that the fan seems to be working, but which fan?

You might mean the fan in the power unit, or you might mean a case fan. Have you checked inside the case to ensure that the fan on your processor is working? If it isn't, your processor would quickly overheat, and cause problems similar to what you describe. If the inside of the system is full of dust and clogged up, that could cause overheating problems as well.

Check inside the system case to see that all fans are actually operating.

I too have just started to have the same problem, but my computer is pretty new.

Specs:
AMD Athlon XP 2800+
512 DDR 3200 RAM
MSI K7N2 Delta - L Mobo
40 gig HD
Radeon 8500
Windows 2000 Professsional

Power supply and processor fans are working, and I have 3 more case fans running fine as well.

When my computer shuts itself off, I have to go to the back and switch that button to off and then on before it starts up.

Also, the computer turns off at random times, and it has only made it to the startup screen once before turning off. It usually turns off at the scren that says Loading Windows press f8 or whatever for troubleshooting (The screen right before the one with the Loading WIndows 2000 Professional, and there's the color picture.) But sometimes it doesnt even get past the, ummmm, lol, omg I forgot what it's called. Umm, where it checks for the cd-rom, floppy, and HD. Anyways, that's what happens. Hopefully you can enlighten me on my problem.

Another problem that might be linked as well is for some reason when I play Call of Duty, sometimes my computer will just turn itself off. Then, after I turn it on again, if I don't play Call of Duty, my computer will fine for hours and hours. It has yet to turn off on me when I'm not playing CoD.

Well those are my problems, any help would be greatly appreciated.

The issue sounds as though it is a CPU over heating as mentioned before. Even if the Processor fan is still working this may be the issue, specially with a newer machine as it runs at higher temperatures. Stop turning the computer on at this point untill you make sure the next steps are taken as you may damage your processor from overheating. unplug the computer from the wall, and open it up. Remove the Processor fan and wipe of all the heating compound from the processor and the processor fan. Make sure you go buy more before all of this. Re-apply new compound across the processor's surface evenly. Then reinstall the processor fan and close up the computer. If this doesn't work then at least for a few dollars and some ime you have ruled out the processor as the issue and you are sure not to cause further damage to the CPU.

I have just started experiencing this same problem. Just started happening out of the blue. I too can not get it to start up until I unplug it, or switch off the shut-off switch on the power supply.
I have the case open and it sounds as if it has to wait for a capacitor to discharge before it will allow you to turn it back on again.

I have changed my PS, but am still getting the same problem. I have completly blown out all (or as much as I could) of the dust from my tower.

Both of the fans are running, both CPU and PS.

At this point, do you think it would be the heating compound or something else?

This is what was happening to mine when my processor was overheating due to the heat not being spread across the processor properly ( this was a factory applied condition as well). The wait I had to expirience was due to the proccessor having to cool slightly before I could try to start it again, so if you see any bios when you start it and it actually starts, then reset the heat sink to the processor with new heat compound.

This is where it gets imortant for you> I beleive the issue you are having is a fried mother board. When I had a fried mother board, I had to disconnect the power from the wall, after each attempt ( or press the reset button two times for a response). the cause of my problem was a bad power supply. I didn't realize it at the time because the power supply worked when I put in a new mother board, but after two weeks that mother board was fried too. I knew that motherboard was good cause it was in a machine I had used for just over a year with no problems. I got a new motherboard and replaced the power supply with a good one and all has been well for six months now and still going. DO NOT CHEAP OUT ON YOUR POWER SUPPLIES! They will end up costing you more money in the end.

I have the same problem, turns out MOBO is now dead, it has exactly the same as described. Would boot to winxp and then just turn off. The on/off switch would no longer work. I pulled the mains and put it back in. As if it was giving it a booster.

Then it would boot and then:eek::eek: die.

There are many good answers here, there are also a lot! of people with this problem.
The best answer was the person that mentioned the Capacitors.

They are cheap, they are all over the board and in the power supply, they will fail, right away or after years of being hot.
Capacitors are for sure absolutely the answer to 70% of the "my system shuts down and I have to unplug" problem.

I built a computer today,
AMD Athlon X2 4600
2gb DDR2
36GB Raptor
7950 GX2 eVGA Video Card

Everything was working fine, got windows installed, and then went to install the video drivers, it restarted my computer and never turned back on. Now when i try to boot up the computer it doesn't even go into BIOS, it powers on for 10 seconds, everything spins, and then shuts right back off. Any ideas? Thanks in advance.

Try taking the fan and processor out, clean the paste off of them with a dry rag, reapply the paste and reset the fan onto the processor. If that doesn't work then you may have a MoBo that is fried and would be considered DOA by the company if you have only had it for a week or two. The place that sold it to you should then replace it, if you have had it longer then you will need to get a RMA through the board manufacturer so they can replace it. If you see anything on the moniter that suggests the Bios is working then it is unlikely that it is the motherboard. Make sure your power supply offers enough power and in my expirience NEVER use the power supply that comes with a case when you buy it.

Im having the same problem.

When i power the computer on and go to bios, it can stay there for hours with out turning off. I left it on for 2 hour and it did not turn off.

But when I try booting to Windows XP after the Loading Window XP part, it look like the cpu fan turn off. But the Powersupply fan is still running. I have to hold the power button for 5 sec to turn it off.

I tried a few stuff in the pervious post. I even try to reinstall window but after trying to copy files it wound do the same. I try putting my harddrive to another computer as slave, it would show all my file, so i know its a good hard drive.

Do you guy think my motherboard is broken?

Thanks for any help.

the easiest way to check the capacitors is to look at them, when they have overheated the top will "dome" and split, you will see where they have leaked. by the way a capacitor can take a major battering and still work, I've seen motherboards with several blown still functioning.
I'd go with old heat paste, just get the proscessor fan and heatsink out, give them a good clean and renew the thermal paste, you only need the tiniest amount.
also check the thermal cut out setting in the bios if it has one 75degrees should be fine.

well, my power supply blew up 3 times already, so i replaced it with a new one. OK, this new power supply worked for about 1/2 a year now (maybe) and now I am beginning to have the same problem these other people are having.

Basically, my computer starts, press the button and it turns on for like 2 minutes? and then automatically shuts itself down. After that, I have to wait 20 seconds to turn the computer on orelse, it will just shut down straight after i press the button.

However, if i continoue to turn my computer on/off and on/off, eventually it will stay on. Just like now, how im replying to this message.
