Hi i also have an amd fx 6300 and i am using an asus motherboard M5A99X EVO R2.0 and have 8 gb ddr3 ram and an amd radeon hd 6750 and when ever i try to play games such as saints row 4 or even the walking dead my computer freezes after a very short time of playing them and also when I try and design something using autodesk the computer freezes after 5-10 minutes and at first I thought the graphics card had a problem so I put it in a different computer and it worked fine so what could be my problem.
