Built a new computer about a month ago and ever since then whenever I play a game or run anything I blue screen. I un-installed the drivers for AMD and when I did that my games did not crash but then again they were laggy becaus.e I did not have any grahpics drivers. So I tried re-installing it and then the same problem occurred. So my main problem is to know if it is just the amd driver being faulty or the graphics card. I have a Radeon 7870 and im running windows 8. I have tried using a driver wipe software but it did still not help. Any help is appreciated
