Strange thing happened yesterday. Was working online, Norton put a flag up that there was high CPU usage, a fan kicked on, so I figgered something was warming up. Backed up my work, closed down my programs and shut the computer down. No problems, right? Went back to start back up and no response from power on. System is older, Dell 8400 series that runs 24/7. New mobo back last spring, No indications of any problems prior to this. I didn't have time to tear into it yet, as I had some other issues that were more pressing at the time. I'm not springing for another mobo, if it's definitely gone (hard to believe though), but I can get another PSU in a day or so. Only other option is to save the HD for a slave so at least I can get my data off, or maybe try to set it up on this machine . Any ideas would be appreciated.
