So I had my cpu overclocked to 4.7ghz and it ran perfectly with my r9 270x. Upon installing my ex 480 bf1 freezes within 5 min every time. Setting my mobo bios to default fixes the issue. I tries overclocking to only 4ghz on stock voltage and with the same settings i had at 4.7 and it still freezes. I also got one bsod saying something about an ati driver failure. What could be the issue? When overclocked even a little the pc freezes as does the sound and I need to restart pc. fans are loud upon start up any suggestions? my cpu is fx 8320.
