Never go into safemode unless you want to tweak your computer
So you got a black screen of Shooooock
. Or was it called death back in the day. White/Black/Blue. The blue ones actually made you do some work. That is re-installing the OS lol.
Seriously??? You go into Safe Mode to correct problems with your PC, that's what it exists for. You go into Safe Mode to run diagnostic tools like MemTest or ChkDisk, or to run System Restore or things of that nature. I think you're getting Safe Mode confused with your motherboard's BIOS.
