A couple of days ago, my Nvidia driver needed to update, so I let it. After it updated My computer started freezing randomly. Then i figured out it freezes when i close a program. After i close any program it lags for about 5 second, then BOOM, completely freezes. I can't do anything at that point, I have to hold the power button and restart it. While the program is up, it works just fine. I think it's a driver issue because I ran it in safe mode and no problems happen, but I don't know how to fix it, or even what to do. Please help?
