Recently i changed 3 times a PSU and now i have a ANTEC 750TP,with amd Llano 3850. It is not buzzing ,but this PSU is only buzzing in games?? How the hell can that be.. Stressing with AIDA,nothing.. Limiting to 60fps with ATI tools nothing. I tried everything!! but none of these helps! oh one thing is ok,and that is when i set my CPU to 800MHz.
