A couple days ago I installed new drivers for my GTX 970 all was going well but I noticed a lot of system lag and constant freezing. I usually put my computer to sleep and then wake it up because the boot time is very slow, but once I would wake it up it would freeze for a while and then come back but it would be very sluggish. I was playing some games and then when I exited out my computer froze until it went into the blue screen of death. The blue screen happened two more times after that. I removed the 970 to see if all would go well but it is now stuck on the welcome screen. I can boot into safe mode though.
