Hi, This is my first post here, but I have been reading this forum for a long time. But to the problem, I just got my new HIS radeon HD6950 2GB card. I installed the card and drivers and everything went smoothly and it was working like a charm. But when i try to play Dragon Age 2 or Bulletstorm or anything with little better graphics, I'm usually able to play like 10 minutes and then my computer will just shutdown, no bluescreen or any error message just sudden shutdown. Sometimes I'm randomly able to play for something like 30 minutes before shutdown, but it will happen eventually and for me it seems that the problem is becoming more frequent. First i was suspecting that my power supply is going bad, but I can run furmark for an hour (or more just didn't had patience to run it for longer) and after that GPU temps were 93C it is a bit high but i guess with amd cards thats normal.(And my previous cards were 2x 8800gt in sli and they were working fine) My system: processor: Q6600 mobo: MSI P6N SLI V2 Memory: 4GB Kingston HyperX PS: Some random 4-year old 650W powersupply OS: Windows 7 64bit CCC version: 11.2 I know that the rest of my system is bit oldish but I'll update it more when I get the cash... But still I'm suspecting that my PS is bad because it was like cheapest 650W PS i could find 4 years ago, and it has been running those 4 years pretty much 24/7. Or do you think that I should just RMA the card?
