Windows Xp dual core problem...AGAIN

[Apokalipse]

So the lower frequency made my monitor go all crazy? But how am I suppose to not let the CPU test get my VGA to a lower frequency or change it to 2D?

It isn't the lower frequencies itself, but it might cause instability if the GPU suddernly changes its frequency while it's in the middle of something.

And for the VGA, it's a 7600GT that I got a few weeks ago. If you're suggesting to run it at a lower speed, since my VGA is at 668/768 right now, how much do you think I should lower my Core and Mem clocks by?

what are the stock speeds?
