Graphics card failing?

Got a 7950, and today it started throwing up random green/red pixels on my screen, mostly on GPU accelerated programs.

So I thought it might've been the 12.11 drivers since I started noticing desktop glitches then, rolled back to 12.8 but problem was still there. Underclocked the card on both the core and memory but still had the problem. Turned off the PC to let it cool down over half an hour, but problem was still there. Then I tried the onboard IGP, and it was all fine, everything was pixel perfect (apart from the lag :p). Is this a sign of a dying GPU?

EDIT: Forgot to add, running heaven also brings up strange blue spark looking artefacts as well...

Well I'm away for uni so I won't be able to do more tests on it until friday, but I'll give that program a try, I have a feeling it's the VRAM.

Card is Heaven stable strangely, doesn't crash just loads of artefacts and mistextures in a few games.

Temps are fine as well, 78c max under load.

And nope, Sapphire, was the cheapest 7950 on OcUK during release.

I'll give my 6850 a go when I can get back on my desktop.
 
Bump on this, back at home now. Decided to leave Heaven running for a couple of hours, graphical glitches and artefacts but still oddly stable with no crashes. The green/red pixels still randomly appears like static on things like Firefox/Chrome, Windows Media Player, MPC and any other stuff that uses the GPU for acceleration.

Anyway, installed the 6850 back in, and all is fine again. Guess that means it's time to RMA the 7950... What a nice present before Christmas :rolleyes:.
 
have you done any overclocking with the card and third party software like trixx ect? sometimes it leaves the oc voltage enabled and doesnt reset it to default,so id check that you not runing with a high voltage

I did initially, 1ghz on the core but then when the summer came I returned it back to stock and left it ever since. Never touched the voltages either, I'm too scared to play with the GPU voltages :p.
 
its only if you alter voltages ect,its probably memory related if its artifacting they do get hot,you could check the heatsink is making good contact thats if it cools the ram im not sure,other than that you can only rma
 
Well thinking back on it, I did notice I do get random glitches every now and then when I first got the card. I thought it was just a driver problem and will disappear after a few updates, and they only cropped up for a split second every now and then so didn't really bother me.

Hmm... thinking about it even more... the card was probably ever so slightly borderline faulty ever since I got it... And only decided to become even more noticable right now.

I thought that when I got my old 6870 last year, it did precisely the same. Only when it went in my sandy bridge PC (it was in a AMD rig until then) I thought the card was at fault. Thank the lord for Asus 3 year warranty, an MSI 7850 is winging its way to me now. :)
