I have this really strange artifact problem that only seems to appear in 3D games. I've actually asked about this earlier in the thread, but I'm hoping that someone here will recognize this problem and have some idea of how to fix it.
Here's an image of a keyboard in F.E.A.R. 2.
It looks like the texture didn't load correctly. I have similar problems in every other game I've played. This only became apparent after I accidentally lowered my GPU fan speed, which likely caused the GPU to overheat. I RMA'd the GPU, which should be delivered within the next few days, but the onboard graphics is still showing similar texture corruption or artifacting. I've tried formatting my hard drive and reinstalling Windows, I've reseated the RAM, I've made sure that none of the wires are loose, but nothing I've done so has had any effect. I've also used hardware diagnostic programs to test my CPU, RAM, and VRAM for errors, but no tests have turned up any errors. I feel like I'm running out of options, aside from replacing every potentially defective part of my computer (which I can't afford).
