Hi all i'm hoping someone can answer this for me. I have a problem where my graphics card will crash after starting a game, soon after starting windows. Once it's spazzed out for a bit (screen goes black flickers on/off etc.) it will then run fine for hours can start stop games etc. it's almost as if it crashes when the card isn't (warmed up). xfx haven't been very helpful, i think the card is out of warranty (it's older than 1 year) so i'm a bit stuck! i'll paste my build below. Any help would be much appreciated it's driving me nuts! i've tried removing drivers etc. (used driver sweeper) i'm getting to the stage of rebuilding the machine...
XFX HD 6950 2GB GDDR5 Dual DVI HDMI Dual DP Out PCI-E Graphics Card
Coolermaster CM690 II Lite with Coolermaster GX 650W PSU *Special Offer Bundle*
OCZ 120GB Vertex 2E SSD 2.5" SATA-II Read = 285MB/s, Write = 275MB/s 50,000 IOPS
Gigabyte GA-P55-USB3 P55 Socket 1156 8 Channel Audio ATX Motherboard
Western Digital WD6401AALS 640GB Hard Drive SATAII 7200rpm 32MB Cache - OEM Caviar Black
Intel Core i7 870 2.93GHz Socket LGA 1156 8MB L3 Cache Retail Boxed Processor
Crucial 8GB (2 x 4GB) DDR3 1333MHz Memory Kit CL9 1.5V
*** UPDATE ***
I have checked the temps and it basically ranges from 35ish to 70ish deg depending on load. I thought a 650w PSU would be perfectly adequate for this sort of card? Thanks very much though i will take your advice and hopefully figure out what the problem is. Can you recommend the right wattage for a 2GB graphics card? I have also checked event viewer and not getting much info it just says something like device driver stopped responding or something like that... I also don't think it would be overheating because it would be crashing constantly? The card seems to run fine for hours once it gets going...
