"Knock Knock, "hollow sounding echo" is anyone in there? Try running the processor at it's intended frequency at least you can eliminate the overclocking as the cause of the problem. Overclocking should only be done If you are desperate for the extra horse power not as a mater of course. You want more horsepower and expect it to be stable then pay for it, get a faster processor." At last, someone talking sense on this subject! Phil
