This doesn't sound like a power issue if everything else seems to remain powered. It is likely that your three-ish year old hard drive is failing - abnormal clicking is pretty simple to diagnose. Back your data up, then back it up again. Make a backup of the backup. You can get a large replacement drive on eBay pretty cheap (i got a 120 GB Maxtor for $120). Be sure you get a 7200 RPM drive - your machine will be noticeably faster than it is now. Furthermore, the silent beauty of your cube has likely been overtaken by a semi-annoying whine from the aging drive. A new hard drive will be whisper quiet. Now stop reading your email and back your hard drive up. www.trev.com Do it yourself tech support and essential tips from a Genius.
