Don't remember hearing about the cooling fan issue. It's really
starting to sound like a power supply gone bad, but check the fans. See
the system first starts up. And that should be fan/wind noise
try WTB on lemswap. Give model number and sales number of your quad to
the machine. Hope all that other stuff I suggested turned out OK. Just
be careful and patient. The AC cord should be OK.
Anyway, keep at it. Replacement power supplies cost more than hard
