then in safe mode run it then try installing again
Did so. Same issue. Boot into windows, display comes on my main monitor for a split second and then goes black, my second display that is running of the integrated graphics stays on but i cant do anything on it. To resolve i have to reboot into safe mode, clean the drivers, boot into windows, then system restore.
Working fine for me....
Actually, I had alot of pc problems ever since 14.1 came out. I recently got 14.2 to go along with Thief and those problems have gone away for now.
