After anywhere from 10 s to 1 m after starting a game, I am kicked out to the desktop. I started with a GIGABYTE GV-R667D3-1GI Radeon HD 6670 1GB, and after reading multiple sites say that it is likely driver updates or a failing video card I bought a EVGA GeForce GTX650Ti Boost SuperClocked 2GB. First of all, it works sometimes, and when it does, man is it a nice difference!!! Great card. I initially had both cards running simultaneously and it worked fine. Next day, same problem. So I took out the gigabyte card and games worked again. After powering off and back on again I am back to the same problem. I've ran multiple anti-virus programs, updated drivers from a variety of sites including the manufacturer and no go. Another dilemma I think may be linked is that my windows "time out", by that I mean that after a minute or so after being on a website it times out as if I had clicked another window and so I have to re-click it over and over. This is happening as I type this and it's pretty annoying. Can anyone give me any leads?
