Description of problem:
After the machine completes the boot, enters the runlevel 5 and I log
in, it freezes after a few minutes of usage, during common operations
(I am downloading a file using scp, I am opening "Save" dialog in
mozilla, I click on a link in netscape). The mouse and keyboard cannot
be used. It doesn't respond to ping, telnet, Power button. The only
way to restart it is from Reset button. 
I tried to boot it in runlevel 3 (no XServer started) but it freezes
as well (this time during an rpm run, for example) 
NOTE(!): RedHat 7.1 installed on the same machine, without any change in
the hardware configuration, and no exotic drivers, works flawlessly.
Win2000 works without a hitch. No thermal instability, Intel Active 
Monitor shows 30/29/33 Celsius for days.
