Problems since formatting Windows 8.1

[power2015]

I recently formatted Windows 8.1. Since then i am having some issues. First the screen sometimes completely freezes and the mouse cannot be moved. Also i had 2 BSoD with the error 0xa000001.And finally today 10-15 minutes after i opened the computer the screen froze then went black and restored again and then it said "Display driver stopped responding and has recovered" after 15 the same thing and then after 5 it started happening again and when it restored it froze instantly and the it continued to do the same thing at a loop (freeze,black,restore,freeze instantly again,...). The graphics card is not overheating. What can i do? (Sorry for my bad English)

Have you tried updating your drivers?
