when do you know when video card is dying?

post #1 of 9
Thread Starter 
I got an XfX 7900 gt bought about a year ago..
the only things i ever did to it was oc it a bit.. like 40 mhz and replaced the loud and tiny factory fan with a zalman vf900

but recently its been freezing on games and giving nasty color patterns, screen distortions and artifacts.. looks really bad.. i also get some spots on the screen while in windows that look like dead pixels but they are not.

i would like to know if it has no fix and what could have caused the problem

ive tried updating drivers.. reinstalling windows.. reinsalling games but still no fix

Artifacting is a tell tale sign. Try downclocking it a bit.
Overheating also could be the cause. Check the core temps with somthing like ntune or somthing like that.

Yeah I was just about to say if the artifacting has been getting progressively worse it's probably dying.

Maybe Your PSU is dying. When your gpu is under load it drawing to much for your psu to handle? maybe...

Take the GPU out and see if any of the capacitors are leaking. My friend had an Nvidia card with 2 leaking caps...needless to say we had to get him a new card....

It could totally be the card. Some of the 7900GT's were defective. I have two friends that both ended up with bad 7900GT's that had to be RMAed.
