any of the options in this site helps;
Lately, my computer, win XP Pro, SP2, seems to have a minor problem with shutdown/restart. I click to shut it down and nothing happens. I click it a second time and it shuts down. Same thing with restart, I click it once, nothing happens, click it a second time and then it restarts. Lately, I get the "End of Task" coming on, when it finishes and I then click 'end of task', it then shuts down. I have run the usual spyware detectors, Spybot, adaware SE, microsoft anti-spyware, AVG7. Did disc clean up, defrag, scanDisc. Thanks for any advice.
