Random FS lockups -- another cause

Got hit with this (and resolved this) for the first time last night. The cause? One of my case cooling fans went on the blink.... It started to cause an excessive draw on the power supply, and the system would freeze solid under load.... Removed it, and life went back to normal...Thought I'd share this with those who struggle over these issues. I diagnosed the problem using my monitor included with my MB, which was getting alarms on the -12V indicator... Anything can be the cause of lockups--so if you have case fans getting on in years, that's another thing to look at....-John
