Error"Driver stopped responding and has successfully recovered\"

For several years pursuing error"Driver stopped responding and has successfully recovered. The game or app. Everything seems to be clear. Either the driver update/rollback, remove the overclock (if there is one) or just buy a new video card. But it was not there. I have already changed the 6 cards, 6 his mother! And you still get the error. And drivers updated,and acceleration was removed (even understated), the power supply changed, BIOS updated, changed the thermal grease where possible (even on bridges). It did not help. Then I decided that what components are acting up. Replaced the PERC 3 times the RAM 2 times, BP 3 times, 6 times the graphics card, hard drive, CPU cooler, OS, different set. NO-TH-TH. Still finishes off this error. Only motherboard change, that's all. Have a new PC. And benchmarks on ultra goes with a Bang! (Not counting fps of course). (But off when idle, sitting in the browser or playing a game 2005-2013 year so you can listen. Please help! What a curse is?
