Ive been using the mac OS for over a year now on this hardware

Asus A8N-SLI
Nvidia 6600
AMD Athlon 3800+ X2
2 gigs ram

and these operating systems on separate hard drives with chameleon RC3
Leopard
Snow Leopard
Windows 7

For some reason however after about a month in I start experience a graphical glitch, it starts out slowly and then occurs so often it becomes annoying. First it will start whenever I play a video (on any media player or online). The screen will go black for a split second then go blue for a few seconds and then go back into the normal screen. This will constantly repeat itself every so often. However If I make the video window smaller it will some times alleviate this problem. After a while this will occur while i'm on the screen saver, while I use expose, while I use photoshop, when i move windows around quickly.

I use an EFI string to get my graphics working, I should also note that I also get the same problems in snow leopard however they occurred from the start and are much more frequent when using Quicktime X than other media players. The strange thing however is that I can play games without any trouble, accept when exiting the game then I sometimes have to go through around 5 minutes of this flashing If anyone could give me suggestions on how to alleviate this problem on leopard I would be very grateful and even more if you had a way to fix this on snow leopard as well.

BUMP
Camon dosent anyone know? I really need help with this.

A month in from what?

What operating system does this happen with mostly, leopard?? Not all all in windows, never in windows?

If it's in leopard, have you used the 9.80 kernel? could try replacing the boot with netkas pe efi 10.5 and see what happens. update allt he customs kexts you use

You say quicktime x and other media players... have you tried the AppleUpstreamUserClientDisabler.kext in snow ?
