Hi, I receieved the parts for my build yesterday morning. Asus GeForce GTX 570 DirectCU II 1280MB GDDR5 PCI-Express Graphics Card Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - OEM Asrock Z68 Extreme4 Intel Z68 (Socket 1155) DDR3 Motherboard Cooler Master CM690-II Lite Dominator Case & GX 750W Power Supply Cooler Master GX 750W '80 Plus' Power Supply Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit Akasa AK-CCX-4002HP Venom CPU Cooler Everything seemed to be working fine until I tried to run some benchmarks. I tried to run 3Dmark 11 test demo, 3DMark vantage test demo, and also the unigine demos. Almost everytime I run a benchmark It crashes with the "nvidia display driver stopped working and recovered". On the "Jane nash" test of Vantage, it seems to crash at exactly the same frame every time. But the odd thing is, on both 3Dmark 11 and unigine, I managed to get through a benchmark a couple of times, and then other times it would fail. The error I get with 3DMark is And the error I get with the Heaven 2.5 bencmark from unigine is: The errors seem to be random on 3DMark 11 and heaven 2.5. Does this look like a faulty card? What else could cause this? I would like to know what sort of tests OcUK would do to test for a fault, so I can do it myself and not waste money. Also, I had the latest drivers installed.
