After Installing the last Geforce BETA Drivers, it seemed to be working at first then my screen went black which is usual for installing drivers, i didnt panic then i realized it never took this long i waited half an hour and it was still black, so i shut down the PC by holding the power button which usually fixes my problems. but this time it didn't start up, its just black. i contacted Microcenter and they said it was most likely a driver issue and said to bring it in so they can restore it. sincei cant cause one of my screws is like for safety and cannot unscrew. is there anyway i can system restore or boot into safe mode with looking a monitor! please the people of tom HELP ME!
