My computer has been giving me one problem after another, about to go office space on it. Just reformated with Windows 7 ultimate, computer was still laggy and locking up so I upgraded old video card with the gigabyte geforce gtx 660. Computer started running better after that but the new graphics card killed my power supply while I was in the middle of playing the new batman origin game. Rushed over to altex and got a coolmax 600 watt power supply since that's all I could afford. Now my computer has been locking up again. Think maybe ram sticks in motherboard might be going bad but I'm wondering if I need a new motherboard since mine is several years old. Any advice on what kind of motherboard I should get in the $100-200 range that would be good for gaming would be appreciated. Thanks!
