I just bought a SAPPHIRE 11188-22-20G Radeon HD 6950 2GB 256-bit GDDR5


and every time I run dirt 3, Battlefield 3, or Starcraft II my computer freezes within 5 minutes of usage. I have updated the new drivers and bios for my computer and already RMA'd this card.

Please Help.

it can be from graphics card , drivers,heat...etc OR Ram(take them out from the slots and clean the golden pins with some white clean paper ) . After doing that come back and tell me if it worked!
Good luck

What do you mean you have already RMAed? Have you sent one back as faulty and got another one and its the same? If sounds to me like possible over heating or not a good enough power supply.

Sorry I should have said the computer specs:

Case: Rosewill Challenger Case
CPU: I5-3570k
MOBO: Gigabyte Z77M-D3H
PSU: OCZ 550W 80 Plus
SSD: 120gb
GPU: Sapphire 6950 2gb

And I will try to clean it off!

@simon12 i have RMAed it and it was the same, so i will try to set better airflow

Just looked at youer case and its the same as mine but I bought mine unbranded. As stated it could be an overheating issue run HWMonitor to check you temps while gaming just try to get out before the crash so you can see what they reached. What fans do you have?

Make sure the temperatures are stable.

There is a 90% chance a heatsink is not mounted properly mounted/come loose.

We don't even know his temperatures yet.

From the info he's given temps seem to be the only odd thing, there can be loads of other things like BIOS flashing and Ram issues, but I'd guess temps.

Okay so atm the video card's temp runs at 60C when i game and the cpu runs in the mid 40sC

Perfect temps.

I asked a friend on his opinion about this, and his only solution is that i need more juice for my graphics card? he said my 550 watts isnt enough and i should get atleast 650 watts?

Best solution

I wouldn't say that, I've got my 6950 on a fully loaded system with like 3 harddrives and an overclocked 2500K with like 8 fans and I've got an Antec HCG 620W. I think it has 48a on the 12v.

But by the sound of it it does seem to be a PSU issue. How many amps on that 12V rail does it have?

Could be a faulty PSU, cox ideally for the stuff u mentioned in the pc, a quality 550 should suffice. How old is the PSU?

Your PSU should be fine. You can buy a PSU tester for $10 and check. More than likely the cooler isn't mounted properly or the thermal paste hasn't been applied properly.

Except his temperatures are fine.....

Yea temps look fine(pls monitor the m/b temps too). As rd2cyp mentioned check for the psu output using a psu tester, not too sure if that will give u accurate results without any load on the components. If it wasn't giving enough output the pc wouldn't boot, but it's rebooting only with load. If you have /can borrow a spare 600w psu can save u those 10 bucks. If not that's a start
