I head to the Event Viewer to look for clues.
Also, if it has a warranty I let them fix it and always have the latest drivers, BIOS, and absolutely no SPYWARE.
Since I applied SP2, my PC hangs whenever I try to put it into standby mode, with the following message: "Preparing to go into standby." When this happens I can't access task manager to troubleshoot the problem and have to power down. Before SP2, this would happen only occaisionally; now it happens every time. Can anyone suggest a technique for troubleshooting the problem?
