|This has happened a few times in the past, but I've shrugged it off and unplugged/plugged back in my power supply and rebooted.|
I'm playing a game (Final Fantasy 11) and my computer turned off. No warning or anything--complete shut down. When it does this, the green power light in the front of the case blinks, and the computer will not start. This could mean overheating, but neither the gfx card nor the CPU are overheating (tested by touch--no numbers). It kept happening at the same moment, looking at the same thing. I thought it could be software related, as when I turned around it would be stable, and crash within five seconds of facing the other direction again, but it has since happened somewhere else, and is very consistent in these areas. It seems to be in graphics-intensive situations.
Custom PC, running XP
MSI MS-7309 Motherboard
450W power supply
2.81 GHz dual core AMD X2 processor
260 GB HD
Nvidia 9800 GTX video card
One problem is that my mother board is micro ATX and too small for the video card. The heatsink on the card presses against the SATA jack on the mother board, bending the jack slightly and pinching the cable against its plug.
Thanks for the advice in advance.
