Since I moved my pc to a LAN-party it takes dozens of time to get the computer starting without a boot loop. When it starts my pc screen goes on standby after the windows loading screen while Safe-mode works perfect. Could it be hardware related? because I might have been staticly charged at the LAN-party since I felt electricity everytime I touched the metal of the case. EDIT my thoughts: 2 problems. 1. Bad power connection leading to boot loops (the orange light next to the power light doesn't work with boot loops) 2. Videocard issue leading to black screens and BSOD (atihmpag.sys) --> reinstalled the video card and it seems to work for now.
