Issues With My Girls Comp (Need Help!)

[The Doc]

I've been having issues with my girlfriends comp the last several weeks, and when I game for long periods of time the montior gets plagued with little green boxes (artifacts?) littered across the screen. It gets so bad that I have to exit out of the game. Could my video card be overheating and causing this issue? Her system is has follows:

ECS 954P-A
Pentium D 830
512MB Crucial Ballistix
X800XL
100GB HD

yeah - I'm pretty much sure the vid card is overheating.. make sure the GPU heatsink makes good contact with the GPU and the cooling fan is spinning...

Run a program like ATI tool that will permit you to monitor GPU temperature while gaming.

You could also use Prime 95 and a digital multi-meter to check your power supply voltages while loaded.

if it has overheated enough, it is likely that the card has been damaged and can no longer render images properly. But, as you said it works fine at first, then it is probably undamaged but overheating as stated
