Why is my PC freezing in 3D games?

Why is my PC freezing in 3D games?

This is the follow-up for this thread. Since I wrote it I've done several testing but so far cannot get my computer to run 3D apps correctly.

"Don't forget that 3D gaming is one of the most intensive things you can do on a PC - both for the CPU and the graphics card, so it's not surprising that it works for ""normal"" desktop apps.

Have you tried and 3D apps like AutoCAD or 3D Studio MAX? You can download trial versions of these so you should be able to find one. Open a large scene, render it and see if your PC crashes.

Given what you've said you've tried it looks like it's pointing to a problem with the CPU - is it overheating? How's it cooled? If it's a fan, check that it's connected and spinning freely. Also check that there is good thermal contact between the CPU and heat sink.

Another thing to try is to turn the game graphics down to minimum - screen resolution, texture size etc. and then run the game. If this works OK, turn one setting at a time back up to maximum (or the recommended value) and see where it starts failing. If it's the texture size then that would point to a memory fault (for example)."

"Is there a way to detect how much voltage is going to the PCI-e slot you're using? If you're overclocking, maybe turn down the voltage to the GPUs/CPU and see if that works.

I'd say it was the driver, but you're using two different brands. The only thing that's common, to me, is the PCi-e slot.

This may sound labor-intensive, but do you have another mainboard to test you config with?"
