I have a bad problem and its costing me loads of money to fix (Total $2000). Ive had my pc for 1 year now, about 3 months ago my top Graphics card failed (Running 2x 7900GT in SLI). It completely died, there was artifacts galore, odd coloured pixels (during POST screen aswell) and then one day the graphic drivers continued to fail during any 3D application (in which the App crashed with a not responding). I removed the card and thought nothing off it. But now my Second card which is now in PCI-E slot 1 has started showing the same symptoms, in the same order as above. At first with the artifacts i thought it must be the display drivers but now they are crashing and so are all 3D apps.
Im like OMG***

..............
Ive replaced almost everything. Except the MB and CPU.
Could the motherboard be faulty???? Or the CPU.....
Running Apps like WMP11 or my TV software dont crash.. Im assuming they have some sort of software render override.
Temps are all in the norm..
CPU: 36c
HDD1-5: 38c
GPU: 35c
Sys: 35c
Rest of my specs are on the left<<<<<<
Anyone have any ideas or thoughts..
