I just got a new cyberpower pc from newegg yesterday and it was working fine yesterday, and today I finally started tweaking the settings. Besides my problem with steam, this is the main problem. When I was messing with audio settings, I was trying to get my audio to come through my headset (turned out it was plugged in wrong) and I was in the amd catalyst config program on the pc. When I selected something for the audio settings and the default speakers, the screen went dark and wouldnt come back up. I have tried restarting it 5 times now. I have popped the windows 8.1 disc that came with the pc into the computer and tried booting up that way. I even told it to fix problems that my be preventing windows 8 from starting up. Now luck. I just goes to the windows 8 icon with the loading circles spinning around, and then the screen just goes dark and thats it. I dont know how to fix this. Im not used to windows 8 let alone a big gaming desktop like this.
