Screen corruption

Hello,
i have a Gigabyte GTX460 which shows screen corruption like the third example in http://forums.overclockers.co.uk/showpost.php?p=19335176&postcount=4

That was with my old mobo and CPU. In the meantime I got an Asus Z97 mobo and i5 CPU, installed Windows using the onboard graphics card and got the system the work. So far so good.
When I put in the GTX460 I got the screen corruption still using the bog standard VGA driver on low resolution. When installing the nvidia graphics card driver the system did the BSOD, same as I had with my old mobo/CPU.

Does that mean the graphics card is a gonner or is there anything that I can do to revive it? I cleaned the dust out of all corners, both fans are running and it's not OCed, I can't get that far.

Thanks for your help in advance!
 
That looks like some of the GDDR5 had gone faulty or there is a dry joint under one or two of the chips.
I had a similar problem with a card and fixed it by re-flowing all the GDDR5 chips with a heatgun. The VRAM had dry joints since the card would sometimes run ok if you pressed down on some of the chips and then tried booting. Tricky to fix if you don't know much about how chips are placed on boards.

If the VRAM is faulty then not possible to fix I'm afraid unless you got replacement chips.
 
Cheers guys, I'll see if my brother has a heat gun, otherwise it goes in the bin. Ah, well. I'll be in the market for a new card then
