I bought the Asus HD 7770 2GB model and installed it along with the drivers that came with it. After play LOL for around 20-30 minutes it keeps crashing. I then decided to install the latest drivers from the AMD website. I still get the Blue screen of death and it blurs out so I can't see what is written on the blue screen. I have the Corsair CX500W power supply. Previous to the 7770 I had an 5450 which worked perfectly fine with all my other specs. I experienced absolutely no problems with it. Can you help me out please as this is my first build and I'm starting to get worried. I built this PC with a friend who knew what he was doing but we are both stuck on this problem.
