I built a computer during the summer and I decided to get a (ATI) AMD Radeon HD 7770 graphics card. It worked fine by itself until I started to game or watching youtube videos. Then my computer would completely freeze and I could not do anything but restart it. Then I talk to some friends and family who are used to computers in this same case and they said its the card. So I ordered a new one, same kind but by MSI instead of ATI. I still have both and the MSI is what I am using. My games that I play as well as youtube still end up freezing at some point whether its 3 minutes of playing or 3 hours. The freezing does not happen as often anymore but anything that requires higher graphics gives it a hard time. I turned the graphics on low on some of the games I play like Skyrim or Battlefield 3, though it still freezes. I am not sure what it is but I was thinking it might be compatibility with something else. I would like to resolve the issue but if it ends up that I need to buy a complete different kind of card I was going to go with an EVGA GeForce GTX650 Se or Ti. Another thing I should note, I ran the furmark test and it went up to 65 degrees Celsius.
