I purchased a new desktop computer a few days ago with Win 8.1. After installing various programs and updating windows I am getting the completely black screen with nothing working when I turn the computer on or restart it. If I then press the reset button on my Fractal Design R5 case it will boot up normally. 

My setup is

Windows 8.1

EVGA GTX 970 ssc [with latest drivers] 

Asus z97 Pro Gamer

i7 4790K

16 GB ram

Samsung 500GB 850 EVO

Cooler Master Hyper 412S

There seems to be a lot of different causes for the black screen at startup. Does the fact that I am able to boot up after by pressing reset narrow the problem down?

I remember getting an error message about CPU fan the first time it booted. Could this have to do with it?

Please provide us with your Event Viewer administrative logs by following these steps: Press the Win key + "R" and type eventvwr>enter Expand Custom Views

Upload the .zip file to Onedrive or a file sharing service and put a link to it in your next post * If you have updated to win 8.1 and you get the error message "the system cannot find the file specified" it is a known problem.  The work around is to edit the registry.  If you are not comfortable doing this DONT.  If you are, backup the key before you do Press Win+"R" and input regedit
Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels. Delete "Microsoft-Windows-DxpTaskRingtone/Analytic"

The PC came with win 8.1 preinstalled. There seems to be quite a few error messages in the admin file, though i have no idea how common that is.

Thanks a lot for the help!
