So hello guys. This is my third post for today, but I'm really having troubles with my PC. So today I installed Win7 (was really hard to find drivers and stuff) and I have kinda CPU problem. I have one process called igfxEM.exe that is making my CPU crazy. Also My PC is using only 30% of the processor while playing games and I have really bad FPS.
