Symptoms : All games from , Skyrim to kerbal space program from 911 first responders to Dead Space 2 either fail to load and throw up a display driver has stopped responding and has recovered error , or they load up and then throw up the error a few seconds into gameplay.
(Black mesa source is the only game i have that works flawlessly)
System Specs are
ASUS Crosshair IV Formula motherboard AM3
AMD1100T X6 3.3ghz stock speeds (ECO A.L.C water cooled)
8GB PNY 1333mhz DDR3 RAM 2 x 4gig sticks
MSI HD6950 AMD Graphics card 2GB
XFX 80+ True watt 750 watt PSU
256 gb HDD 7200rpm Seagate
64gb SSD OCZ Agility 3
Fixes i have tried so far
Editing the TDR Time in registry
Doing a full driver uninstall and driver sweep and intall latest drivers
Underclocking (Had some positive effects for some games but only temporarilly delayed the errors which came back)
Brand new PSU 80+ 750watt , also tried a friends 1000watt
Tried Graphics card in another system which can barley run the card... ran flawlessly well at least no errors
Graphics card will pass Furmark, 3d mark 11 and MSI kombuster on current pc no issues. Only when gaming.
Temperatures are way bellow overheating , 28oC on idle and 60oC after running furmark for a while.
Tried a Nvidia Card in my system from my friends PC. No errors ran all games perfect.
Tried a different power outlet in the house.
GPU has latest BIOS
Motherboard has latest BIOS + Chipset Drivers
Tried different PCI-EX Slots all have same error
Tried different PCI-EX Power Cables
(Cant RMA Card as was bought brand new from ebay not from a retailer although RMA sounds pointless as runs fine in another pc)
Does anyone have any more ideas for me ? Im thinking of just going back to Nvidia Cards as i had this same problem with an AMD 5670 on a different motherboard and processor setup
