Help with PC

My computer recently start lagging very badly. It happens when opening and shutting down a game. I end of having to restart my computer most of the time because the application won't respond to anything even through task manager. Also, my Radeon driver keeps crashing repeatedly. Like, seconds after each crash. It's quite the nuisance.
I have
AMD phenom II 3.4 quad Deneb
ATX micro board
8gb Pny ddr3 ram
Seagate 500gb sata
Radeon hd 7770

try to update drivers of graphic card, chip set ect...
if the problem continues scan for viruses and other malwares using a powerful virus guard.
if not recovered use a clean installation of windows and install correct drivers and try with your game.
