I5 4690k and R9 290 sapphire Vapor-x ,Not overclocked. Ehm i dont know if i did a clean install, i installed w10 from the little windows 10 picture in the corner. Nothing should be running in the background. I updated all drivers from the windows 10 device sections. Also i dont think im running out of power, this just started when i download windows 10. The game also freezes alot when alot of stuff is happening on the screen most of the time.
