Hello everyone, Im working on a pc that wont shutdown. It has windows XP pro sp2 with all the updates and all the drivers updates. It has the lastest BIOS. Whats happening is when he trys to shut down, it will freeze on the screen, "windows is shutting down". I have run for spyware, adware, and virus and found nothing. I tried to disable everything in msconfig, and did the diagnostic startup with no luck. I was thinking mabey it had to do with the APCI, but that seems to be ok. If you go into the DM and check the computer is shows, APCI mutiprocessor. So in that since eveything seems to be in order. Im thinking that it has to do with a system file or something. But im not sure what file that would be. Any idea?
