You are absolutely right.

Dirty power signal might cause this too.

Sorry about that squonksc, just deleted my post after going back and re-reading the thread and he did post the model number of his power supply.

Been looking for info on it and from what can find so far it is a cheap no-name PSU (to the point that I have seen that model number even being listed/sold as a 550W power supply).

coloradobeetle if you could, there should be a label on the side of the power supply. If there is can you post what it lists for the amps for each of the 3.3, 5 and 12V lines.

Hi stormy13,

Don't have to be sorry.

Any help is welcome in these kind of complex issues.

Can be a lot of things.

Forget about this, i dont have luck with my system and the win7. Dont like each other.
The power supply : Noname LPK12-30 450W
Motherboard : ASUS P5Q3
And i sad again, everything is working fine, in XP and Vista. The problem coming only in Win7.
All of my temperature is normaly. This computer is on 24 hours a day. This pixel problem is cominng when i try the first Win7 beta, if i change back to XP or Vista, the PC working perfectly. Some other forumthread sad it is a TDR problem with the atikmdag.sys. How can i off this stupid TDR in the registry? In Vista, this TDR problem is solved. But how in Win7.
