The girlfriend said it happened to her before, while she was playing WoW. Just now it happened to me.

Was playing the game, had firefox open to a presumably safe website. and the monitor went blank, which would scream to me video card/monitor problem. but the keyboard and mouse died at the same time. Well at least i know the keyboard did because its a G15 and the LCD went blank. Obviously a cntrl alt del wouldn't work, so i tried the power button. pressed, then pressed and held which according to the option in windows will shut it down. No go. had to flip the power switch on the PSU. Fans and everything were still going while it was "on" maybe a bad/shorted Mobo?

This is the rig, subtract the extra parts of course. it has 4g ram and obviously one case and cpu :thumbsup:
MB ASUS M3A78-CM AM2+ 780V/SB700 RT
CPU AMD|A64 X2 6400 3.2G AM2 2M R
MEM 2Gx2|KST KHX8500D2T1K2/4GR R Kingston
HD 160G|ST 7K 8M ATA100 ST3160815A Seagate
420W Thermaltake PSU

I have basically the same rig in my computer except for the HD and vid card, so part swapping to Troubleshoot wouldn't be a problem, except for the fact that it happens extremely rarely.

When i got back into windows i checked speedfan first. temps seemed fine, forgot to do it in BIOS.. Event Viewer showed nothing. Another thing that may or may not be related, the front microphone jack on the computer doesn't work anymore, it did, but doesn't now, I havent gotten around to taking it apart to see if it came unplugged. The headphone jack works, the USB ports work but the mic doesn't. mic in the back does but not the front. Unfortunately my RMA period just wore out like 5 days ago so to replace something i need a really good idea what it is.

As always any help you can give will be much appreciated.

you have a different video card to swap out with? or integrated? if so try getting it to repeat with either the integrated card or another one.

Update: her computer, the one with the MSI vid card in it did this same weird "shutdown" thing a couple more times then the PSU gave out. When i replaced the PSU I went and swapped her MSI for my EVGA card. Also connected the headset keyboard and mouse to the back panel instead of the top of the case in case a wire was crossed in the front panel.

Yesterday my computer with her MSI card did the "shutdown" had to power down with the PSU killswitch (I/O) When i tried to power back up my PSU was dead. So my thought was somehow the copper from the fan on the video card was shorting to the first PCI slot, so i replaced the PSU and took the MSI card out and ordered another vid card from newegg.

Today, I was wrong. her computer just did the "shutdown" and i'm totally lost.

I know i did the standoffs right, i know there has to be a short somewhere but i have no idea how to find it. help me please lol

A quick summary,

Unit A was having a random semi-shutdown problem.
You took the video card out of Unit A & put it in Unit B
Unit B developed the same problem with the same results.

Obviously the video card has failed & is causing the issue.
One part of the issue appears to be that the video card damages motherboards.

Strip one of the units down to the bare neccessities to make it work & see if it does the same thing.
If it does & you happen to have a spare stick of memory that hasn't been on either since the problem started try it on the stripped down unit.

If you still have the problem it is obvious that the motherboard, CPU, or both has been damaged.
The only way to find out which is to try swapping a known good component for one or the other.
