Mia, as you say ' sight unseen' but maybe this might help:-

You may need to determine whether its a heat/hardware issue rather than a
WinMe issue. If heat related, then the inside of the box may need a good
clearout. (A lot of dust gets sucked into box due to the fan(s) and can
reduce the cooling efficiency)

Boot using your Windows Startup (floppy) Disk and select the DOS Help page
option. Leave it running for several hours, scrolling up and down the pages
every so often and see if it still shuts down/reboots.

If so, then it's a problem with your PC and not with WinMe.

If not, then boot into Safe Mode (F8 or Ctrl keys at boot-up) and leave it
running in that mode for a few hours and see if it shuts down/reboots. If
so, you may
need to disconnect external items of hardware to see if you can isolate it.

Tonight my desktop computer shut itself off. (I'm using
the laptop now). I started it again a few minutes later
but it shut down again after only a few minutes. I assume
it's overheating, but I verified that the fan is running.
I realize this may be tricky to diagnose, sight unseen,
but does anyone have any idea about what may be happening,
and is this something I might be able to fix myself?

Thanks in advance.
