Hi, my Dell Dimension 5150/e510 with Windows Xp Pro  has lately come up with more problems. I will be working on the machine and it will all of a sudden reboot with no errors, well no boot up errors, it does say after it reboots, "The system has recoverd from a serious error." I think it is a IDT SigmaTel driver causing the problem, because it also says "IDT Systray has encoutered a problem and needs to close" Any help would be appericated. Sam
