My PC freezes randomly, seemingly unrelated to any process or task
at the time. I've googled this problem on the web, but I hadn't
noticed any instance of my particular case.
The particulars: ASUS P4P800E-Deluxe MB, Intel 3.0GHz Prescott,
2GB Patriot
RAM, Quadro FX 1300 video card, WD 250 GB HDD, & COOLMAX CR-550B
power supply.

Operating system?

There's a 120mm fan in front blowing over the HDs, 2- 80mm fans in
back exhausting the air out of the case, and the PS carries a 140mm
fan set on high. The CPU sports a TR2TT TR2-M12 copper heat-sink
with an 80mm fan.
The machine will stop dead at any time, i.e. shortly after bootup,
accessing a
drive through Explorer, downloading, just sitting there staring back
ot me, etc. Downloads will stop, the cursor freezes, the Numlock key
will not work on the keyboard, and of course the 3-finger restart
doesn't work. This requires a hard shutdown via the power switch.
After I shut the machine down, the Numlock light on the keyboard
remains on, and generally the machine won't restart immediately.
After perhaps an hour, it MAY start, sometimes halting during the
POST. If I let the machine sit overnight, it usually will start up
again.
What has worked for me at this time is throwing the switch on the
back of the
power supply off for a minute or so, turning it back on, and then
restarting via the power button.
So, what can this be? I hate to think that this is a heat-related
problem
with all the sucking and blowing going on in there.

What appears to me to be words of wisdom recently expressed in this
group, don't have negative air pressure in your case, most importantly
because it will work against your power supply exhaust fan. It might
not matter, but I would need a good solid reason to go against that
advice.

Do you have a decent power supply?

You didn't say how often the problem occurs. If it's frequent, you can
remove unnecessary components, like when you first build the computer,
and see if removing a particular device helps.

Good luck.
