Strange Server Behavior

[Wayne Davis]

You COULD have a flaky Power Supply such that high rail load is bringing 
it out of spec.   Be careful swapping one tho.   Some of the older Dells 
use a proprietary pin-out on the PS connector.  It's the SAME 
connectors, but wired differently.  LOOK at the colors going to what 
pins if you choose to test this theory.  If it this type, you'll smoke a 
PS tester if you plug it into it.  Bulging Caps ( a well know issue with 
Old Dells) on the MB could be a sign of unclean power too.

My 2 cents

:-)
