-=PCTechTalk=- Re: E Machine

Hi Rocky,
    How does the system react with everything other than CPU & RAM unplugged 
from the mainboard?  Do you hear any beeps to indicate that the BIOS is even 
waking up?

Random thoughts while pondering the actual question:
    You mention that the power supply is working, but was it actually tested 
with a PS tester or multimeter?  Even new devices have been known to arrive 
DOA and a working PS would still provide power to other peripherals, even if 
the CPU is fried.  As far as the CPU heatsink being gunked up, things could 
get to a point where it burns itself up, but most modern procs will shut 
themselves down well before it gets to that point.  They will then refuse to 
run until their temps drop below a set point.  Of course, enough heat will 
dry up the thermal grease between the proc & heatsink making it impossible 
to keep the CPU cool enough to run for any significant length of time, so 
that may need to be refreshed.

    Taking everything you've mentioned into consideration, the power supply 
is the most likely culprit here since you said "nothing runs".  If power was 
being distributed at all, you'd at least see the fans spinning, hear some 
activity within the hard drive(s) and be able to open/close the optical 
drive's door.  If all of these things do occur, then I would next target the 
CPU.  If those things occur, but the fans plugged into the mainboard refuse 
to spin, I would instead target the mainboard.  I just wish I knew more 
about what's getting power and what's not.

Peace,
G
