Hi, I'm experiencing some inconveniences recently. My ATT seems to work fine. However, whenever I try to terminate ATT and rerun it again(the same for logout then login), it freezes the system right there. No bluescreens, no warnings. It really confuses me greatly. And so I seek answers here. Regards ------------ Okay I've figured it is the auto-overclocking mechanism that causes the problem. I turned it off and try to repeat the actions mentioned above and no problems at all. Question is, is this considered normal?
