I've had my vista home premium PC for one yr + and its sometimes won't awaken from sleep/hibernate ( usually overnite ) .Sometimes it does, other times NO and I have to pwr down and remove pwr plug, wait one minute. It reboots, usually says windows shut down unexpectedly. I'm up to date with video & windows updates including SP1. No change to intermittent waking problem.checked with HP support. de;leted screensaver. no change Looked at event viewer, but not sure what I'm looking at. Is there a software conflict? How can I diagnose this. Vista should fix this ??? Should I buy a registry/error tool, like REcure. HELPCHUCK
