Windows shuts down on its own

[Guest]

I'm looking for ideas as to why....my system will shutdown without warning.
It's done this while running ME and XP but not while booted in a DOS mode.
I've shutdown all the power management options, have reformatted the system
in both Fat32 and NTFS, have loaded the OS and nothing else. The system can
shutdown in 5 minutes or 5 hours, there's nothing common here. It just stops
running on its own, although the power supply fan and lights keep going. I'm
at a loss for ideas. Has anyone seen this before? The system is an HP
Desktop. Thanks!!!

Could be a power supply issue. If the system has a gygabyte motherboard. That
also could be the issue. On 2003 a number of gygabyte mb has to be recalled
because similar issue.

I don't beleive it's the power supply or heat related because it doesn't
shutdown under DOS and there is very little processing going on when it does.
I've opened up the chassis to help with the heat issue and it still shuts
down.

It may not be heat, but I believe it is a hardware problem. Try
replacing the video card and see what happens.

If that doesn't help, then test the RAM with Memtest86+ from
www.memtest.org. Obviously, you have to get the program from a working
machine. You will either download the precompiled Windows binary to
make a bootable floppy or the .iso to make a bootable cd. If you want
to use the latter, you'll need to have third-party burning software on
the machine where you download the file - XP's built-in burning
capability won't do the job. In either case, boot with the media you
made. The test will run immediately. Let the test run for an extended
period of time - unless errors are seen immediately. If you get any
errors, replace the RAM.
