I'm running Windows 7 64 bit and have the latest windows updates. My CPU and GPU are Fx 8350 and R9 270X. When the system goes to sleep mode i can't turn it back on (wake it up) it's only blackscreen. I've tried moving and clicking with the mouse and also tried pressing buttons on the keyboard but nothing works. I have to force-shutdown it and then start it again. This is really annoying and I know a lot of people have this problem too. I've tried allowing mouse and keyboard to wake up the system through Device Manager but it still doesn't work.
