Heya sports fans!

I got this really REALLY annoying problem with my graphics card (I think). I recently UPGRADED my computer (With new cpu, graphic card, Motherboard and ram) and at first everything seemed fine, but recently I can't seem to play games... Whenever i've been playing for a while (somewhere between 5 mins and 10 mins, it varies) the screen suddenly freezes and becomes a colorfull chaos of pixels, i mean, they're all over the place! stripes and *censored*... and i can't do nothing but restart the comp.
When i then restart, the screen is still messed up, still chaos and it continues like that until i completely shut down the comp and way for a few mins (or 15) then everthing is okay again.

-This ONLY happends in games (seen nothing wrong in windows, yet) and only after a while of gaming.

-As i said, it's a recent problem, in the start EVERYTHING was all happy days.

-I was thinking it could be overheating or something like that (i know very little about computers ) but then again, i DONNO why it would be overheated, it's got 2 massive coolers + a cooler inside the ... erhm... box?

-I wish i could show you a screenie but i can't do anything but restart when it freezes up.

we're talking bout a
2,13ghz INTEL core 2 CPU
1 Gig (DDR2 ?!) ram
Geforce 7600 GT

What els ya NEED to know ? i'm new at this

Thanks for HELPING Oh yea

I'm using Windows Xp with SP2
and all the newest drivers for my graphics card and for anything els really.

donno if that helps Open up the case of the computer and clean out any dust inside.
Don't use a vacuum cleaner, use a cloth.
It definitely sounds like heat to me.If he just replaced all of that there shouldn't be a dust problem.

How about some specifics on the temps?

Sounds like heat, bad graphics card or bad drivers.
