Last year in August I got myself a new GeForce 7600GT Silent 256MB RAM, and since like Jan-Feb or something like that 'till now I'm getting artifacts and flickering in games like Command & Conquer 3 - Tiberium Wars, NFS: Most Wanted. I've managed to make some movies about them, they are BAD in C&C3...
Please tell me what to do, if there is something to be done.
monitor your temps; its obviously a fanless card, so make sure you have good air flow in your case, your heatsink mounted flush and an even coat of thermal grease. if you want to mate a small fan, that can only help....
I have two coolers underneath the video card that are mounted into a PCI slot and blow air upwards, and a cooler mounted on the back of the PC that blows air on the card's heatsink. More, I got a front cooler that gets air into the PC case, and a left side cooler that does the same thing. The temperature of my GPU is a constant 54-55 celsius idle and 65~ when gaming. + it's summer now, my room ambient temperature is high too.
