Troubleshoot to see if the Power supply fan is working properly,and then check the CPU fan to make sure that it is working and not overheating
Open the Control Panel and disable power management and see if the problem still exist

Your solution is ok but, on the software sides so many programs have downloaded. You may right it can be the power supply or the CPU fan, but we should check it thoroughly.

Yes it sounds more like a hardware problem. Based on what little info you give its probably your pc's power supply. When it shuts down by itself does it reboot again by itself? is that what you are saying? How old is this computer and what kind of processor is ot running? what OS are you using? Power Supplies are frequently intermittent when they act up and often overlooked as the culprit. Particularly if its an older machine.

yes, it shutsdown and give me a message that windows will shutdown. Then it boots up automatically. Im using PII, OS-win98.

I've had chronic problems with the newer IBM desktops overheating, and subsequently shutting down. That's probably the culprit. Check the case and CPU fans.

Sorry for not getting back to you after so long clark but hopefully you have corrected the problem by this. If not here is another idea since you answered my question concerning the computer restarting automatically. Most computers include a reset circuit sometimes a switch on the front panel to manually reset the computer. Either way if the microprocessor gets the appropriate signal it will reset and restart. This is a supply voltage to the processor issue. There is a circuit on the motherboard that asserts a reset signal whenever the supply decreases below the factory-programmed reset threshold for at least 100 ms. The reset signal remains asserted for 190 ms after VCC (voltage supply to the chips on the board) rises above the threshold to normal value. It could also have to do with a very brief (fast) brown-out at the a/c wall outlet the PC is plugged into unless you have a UPS on it. A surge protector will not help in this case since it is not a surge but a sag! So You may have a faulty reset circuit on the motherboard (replace motherboard) or a defective power supply (replace P/S).

Ooops! I missed the part about "Windows will shutdown"! Dag!! This now appears to be a software OS issue, not hardware. is this '98 or NT or what? At any rate check for updates or hotfixes at MS site. Try this site,

Please let us know how this was resolved. Interesting.

I am not all here today. You did say OS is 98. The site above gives a path to resolve shutdown problems.
