Computer problem I just can't figure out.... (SOLVED!)

<< < (9/18) > >>

TOK:
My guess is power supply. That supply is a single 12v rail, and they're just do not supply enough voltage for modern systems. Classic symptoms are behaving fine in 2d apps, then going berserk in 3d when the card draws too much power.

Ginsu Victim:
My previous PSU had dual rail and I still had the problem.

 How Hot is the case and CPU?

 Also, Check chipsets that are only heatsink cooled... which are getting way too
hot to the touch.

 Open the side of the case, place a large box fan pointing that way... and do some
play tests.

For some reason I can't get the thought that DirectX may infact be the problem. Maybe the current versions of DirectX have a bug that makes them not work well with the specific vidcard (something M$ would have to fix in a hotfix, or a driver fix (soon, hopefully) from the vidcard makers). I hope for you it is just the vidcard, have you gotten the chance to test the one from work yet?

I had a somewhat similar problem with a computer I bought 4 years ago. I would do anything 3d and it would run at 1-2 fps, it turns out that it was defaulting to OpenGL instead of Direct3D, but the video system didn't have native OpenGL support it just emulated it. Fixed it by ensuring stuff was using Direct3D instead of openGL.

I've got seven fans in this case and temp monitoring always running. I tend to stay in the 38c - 48c range.

I've tried both DX 9.0c and DX 10.

Right now I have the drivers downloading for this video card from work, and I'll see what happens with it.
