Have you installed service pack 3?
Really... it's completely safe to do even on pirated copies of XP and between the bios adjustment and the service pack you should get rid of the problem.
For the CPU usage... how high is it? 5 or 10 percent is not unusual when it's doing background maintenance tasks such as disk cleanup or cataloging file protections.
yeah its between 5 % and 10% but ..im not running any tasks!. , im scared to run service pack 3....the windows advantange program will stalk me forever!! you know the blue star.. jesus..
