Is there something wrong with my GPU?

I have had a AMD Sapphire 7850 for around 2 months now, and around once (sometimes twice) a fortnight (since about 2 weeks of having the PC) the GPU decides to 'play up' for a day. Whenever I try to play games, the screen will lock up and vertical lines will display across the screen; this occurs on games from Skyrim to Terraria. My temps seem fine, no overclocking is applied on the card and GPU usage doesn't fluctuate at any time. Does this sound like a problem related to the GPU?
Here is my system spec:

i5 3570k @ 3.40GHz
Sapphire 7850 2GB
4GB 1600MHz
500W Corsair V2

I am also running the 12.6 drivers.
Thanks for any help.
 
I'm sort of having the same issue. Except with my Windforce 670, the card is overclocked yet this happens @ stock clocks too. After a heavy session of BF3 I may notice blue artifacts/lines on my desktop and across youtube videos, sometimes very rarely I get artifacts in game.

I'm reluctant to RMA this, as tbh I don't think the issue would be reproduced in testing as it happens rarely and only after a heavy gaming session.
 
try underclocking your memory from stock clocks by 150mhz and see if it still happens,artifacts usually point to gpu memory
 
Thanks for all the replies, it's just weird that my whole computer locks up and vertical lines cover across the screen with a coloured background (sometimes blue, sometimes brown, sometimes yellow).
I'll try underclocking and if the problem still happens I'll try reseating the card.

EDIT: I underclocked the memory by 150MHz and tried Terraria for 10 minutes and Skyrim for 10 minutes and the computer didn't crash. After this worked I then upped the memory back to stock clocks and Terraria and Skyrim worked for 5-10 minutes on each. So far so good, I'll leave the memory at stock clocks for now and if the crash happens again I'll try reseating the card. Thank you for the help.

I'm having similar problems.

I'm getting a screen full of horizontal lines .
I boot up the pc get some black screen flashing then horizontal pinstripe lines on desktop. The desktop isn't visable at all.

Card isn't overclocked, is a reference 7850.
New build and all new components,fresh win7 64bit install.
I have done all the typical advice to no avail. I have resat and reinstalled few times, eventually pinstripes appear and lock up screen.

I'm wondering whether it is anything to do with the 2D idle clocks issue, any suggestions?

Cheers

Mine only occurs when playing games. When the lines appear, I have to force off the PC and when it reboots it's all fine... until I play a game again. So far so good still though since underclocking then putting back to stock clocks. I have no idea what's causing it though.

how is your cooling in your system, and OS?
What kind of background software are you running while playing, anything scheduled like defrag etc...(only asking because of the timing of crashes)

In my past experience that kind of behaviour came about from real heat build up.


Back to me-

I tried all drivers and even ones that 'worked' gave me severe artifacting in the form of blue horizontal streaks.

I have a feeling card was damaged on route to me as it was poorly packaged, with just black plastic wrap around the original box . Sellers really should bite the bullet on postal and packaging tbh ;-)
 
Cooling system's fine, 3 case fans and cable management isn't too bad. I'm using Windows 7 Home Premium 64-bit if it helps. Only background stuff I have running is Advanced SystemCare, Skype and Steam. Advanced SystemCare auto-cleans the system when my PC is idle.

Your problem seems worse than mine, does your entire system lock up or do lines appear over your screen? The packaging seems a bit questioning to me, did you buy it from Overclockers?

hmm..

I cannot think what it could be, you maybe should look at your connections etc..see if anything amiss there. Did you self-build or buy off the peg?

If its a off the peg built for you type, I would get builders to take a look for you.
If U have an old gpu about, try gaming with that see if its your card hardware.

my screen is completely unusable, I effectively had to reboot however display is garbled pinstripe.
in hindsight wish I had grabbed from here...sigh


I have requested it be RMA as defective, and have pointed out unsuitable packaging is unacceptable. This is bit I dislike about online shopping, the to and fro and apprehension of whether seller suffers same issues.
 
I built it myself. Underclocking and then returning back to stock clocks seems to have worked so far though (fingers crossed). I don't think an RMA would be necessary for me at this moment in time, I'll leave it for another few weeks or so.
