Hello! I joined the forums due to a problem I am having with my son's PC - We upgraded to windows 10 and everything worked great - better than 7 - he was in heaven and his games played the best they ever did. THEN one morning it wouldn't boot anymore - just en endless PC repair loop where I cannot get into safe mode, or boot from a CD or much of anything.... I can get into bios area (I think) but I can't get the desktop to appear. What I do see when it is trying to boot is a window that flashes for less than a second before it goes into repair. The window is black, but at the top reads winpeshl.exe and then it is gone. Does this mean anything to anyone? Help!
