David <div><div id="SkyDrivePlaceholder"></div> <pre>It sounds like you have a hardware problem. A "clunk" is usually either caused by a bad hard drive or fan. If it's loud and sounds solid, it's probably the hard drive, which might explain why it likes a nice solid reboot at night (you may be getting corruption). If the drive is relatively new (less than 5 years), try using gsmartctl to run tests on your hard drive and see if it is still functioning properly. You didn't mention if it's a desktop or laptop machine. If it's a desktop, checking the fans should be fairly easy. Open the case and check for: -Something jamming a fan periodically (wires run too close to blades, etc) -Heavy dust build-up -Fan not spinning Remember that there is also a fan in the power supply, so check that one as well. If the hard drive *is* bad, back up everything and replace it A.S.A.P. Do a FRESH install on the new hard drive as the system files on your old one are most likely corrupted. ~Doug A.K.A.
