I have a tricky problem with my computer, and would appreciate some help.
Now what it does is the following,
As soon as I start my pc, it does the tests checkups and all that jazz, but when it gets to my windows7 ultimate startup, before the login page, my pc switches itself off, note, it does not restart.
I thought that it might be windows7 so I backed up my files onto my other hdd, and reinstalled windows7 ultimate. And at random points, my pc just switches off again.
next i took out my recently installed ram, and left the old ram in, and it did the same, tried that same thing with leaving in the new ram, and taking out the old ram, still the same problem.
Next, i swopped my power supply with another one i have, same thing.
tried another hdd i have, same deal.
thought it may be a cooling issue like i had with previous pc, installed a cooler master jet, same problem but my pc now runs on 20 degrees and my mobo on 30.
I checked my pc for burn marks, no burn marks.
checked my cpu, none either,
I changed my bios to the fail safe settings, and it still does the same,
to rule out the disc i tried installing windows 7 ultimate from a friend's disc, still the same,
to rule out windows 7 all in all, i tried installing xp, still the same.
my stats ae the following,
AMD K8 dual core,
nvidia geforce 6100 pm-m2 v2.0 mobo
4gb ddr 2 (800) ram,
Seagate 500gb 7200rpm,
samsung 160gb 7200 rpm,
nvidia px8400gs tdx
600watt baobab psu newly installed,
and a standard dvd rw sony
any help would be appreciated
