I don't believe this problem. My system had SP3 for a long time. After installing SP4 was when I started to experience this problem.

It could be some sort of hardware issue. I have a AMD K6 166 MHz processor.

>My brother and I have almost the same configuration on our computers. But he installed Service Pack 3 before Service Pack 5 and he doesn't have this problem. Do Service Pack 3 put something in the computer so the problem don't occure?
