Okay, so when I open my PC(GTX 770 and i7 960) it runs fine. I run a couple of monitoring software such as AfterBurner, Evga Precision, and Intel Extreme Tuning Utility. I can play my games at very good settings and fps right, so I was running Minecraft at 140fps on Extreme. But after like 10minutes, everything goes downhill. All my monitoring software is still running at same speeds, my GPU at 1188MhZ and CPU at 3.3GhZ. But yet, even out of the game, everything is lagging, when I drag Google chrome or any Software around the screen, you can see duplicates trailing behind it. And I can't play any game afterwards and I have to restart and let it cycle again. Please help, this is very annoying and game breaking.
