I have a Win98 system which will not power down and stay powered off unless the power switch on the power supply is turned off. If the power switch at the power supply is turned off and then turned back on the computer will remain powered off. Allother ways to power off the computer will immediately power back up. When you press and hold the power button it will power off, but when you release this button the computer will power back up. When you power down using windows START TURN COMPUTER OFF method the computer powers off, then immediately powers back up. I have changed the fast boot option in the registry and nothing works. Is this a hardware or software problem?

This is a hardware problem. Without knowing the make/model of the PC it sounds like you have a power switch that is supposed to work in a push off - push on sequence and the switch is failing to latch in the off position. I am also presuming that it used to work correctly and has ceased to function properly. This can be checked with a meter (VOM) to verify.

Some more options:
1.) Check the BIOS for a reset option, it should probably be soft boot.
2.) The switch connectors to the motherboard may also be loose or connected incorrectly, check your manual for connections to the switch.

Have you changed something (processor) in your system? If you have a fast computer, it can be faster than the OS and then you can get this problem.
