I have a HP 8510 laptop running XP Pro, Intel Core 2 T5600 and when I select Shutdown or Restart it closes network connections but sits at the blue screen, (not the BSOD) and will not shut down or restart without having to hold the power button on the laptop. I have shut down all processes before I shut down and scanned the PC for any spyware and malware. Does anyone have any suggestions on how to get this to work properly?
