I'm building a HTPC with a Pentium 4 3.2ghz Northwood CPU, two 512meg
sticks of Mushkin PC3200 ram, Zalman CNPS 7000-A AlCu heatsink, Arctic
Silver Ceramique thermal compound, and a Intel 865 PERL motherboard. The
power supply I'm using is a 400w Seasonic Super Silencer. When I 1st
powered the computer the heatsink fan started up and I got a very rapid
series of beeps. I thought the problem might be caused by CPU as the
Intel 865 PERL instruction manual stated that seven beeps indicates a
CPU problem though there seemed to be more than seven beeps sounded in
the attempt to boot.
So I removed the motherboard and power supply from the case, removed the
heatsink and CPU, cleaned off the old thermal compound with 91%
isopropyl alcohol and reapplied a new coat os thermal compound. I also
removed and reinstalled the two sticks of Mushkin RAM. I left the
motherboard out of the case, jumpered the off/on pins on the motherboard
and reconnected the power cables.
Now when I try to boot the system I no longer get any beeps. Instead
after about 5-7 seconds the fan on the heatsink stops spinning. I've
tried attaching a video card but the machine never gets far enough along
to output video. Any idea as to what's wrong. I hope I havent fried by
motherboard or CPU. Thanks.
