Computer Crashing:

[Navyguy]

I have a Dell Dimension 8200 with XP, SP3 running Windows Firewall,
Avira antivirus,
Spybot (for updates only), Spywareblaster, ATF and Hive Cleanup and
all the programs work well together and are up to date.

Recently, my computer has shut down 3 times in as many days for no
apparent reason. The last time (today) I was watching a movie online
and it just crashed! (the screen goes black and the Computer (CPU)
stops functioning yet the modem shows I'm still connected to the
Internet (all lights green). I"ve checked for any updates and ran
scans for viruses but it all came back ok. Also, I’ve already replaced
the hard drive a few years ago as well.

I would appreciate any thoughts/suggestions on what may be happening.
Thanks,
Robert

Thermal problems, maybe?

Unplug the power cord, then open the case and vacuum out the dust and
lint, especially in and around the cooling fans. If you have one, or
can get one, conveniently, use one of those tetrafluoroethane gas cans
or a similar dust blowing can to blow the lint out of the cooling
fans and especially around the CPU. A small soft bristled brush may
help dislodge any clinging lint that can't be easily blown away.

To minimize the chance for damaging the motherboard components with
static electricity, be sure to make contact between your hand and the
case so any static charge arcing and sparking will be minimized. Make
sure nothing is blocking the air flow at the case vent openings.
