I would agree, but this system is < 2 months old.  I'm thinking more along
the
lines of a defective or infant mortality part failure.  Scans through
/var/log/*
haven't revealed anything clearly an issue, but I did find this interesting:

In /var/log/Xorg.0.log.old (yesterday's log) and in /var/log/gdm/:0.log.1these
lines appear at the end:

AUDIT: Sun Sep 16 22:12:40 2007: 4351 Xorg: client 2 rejected from local
host
AUDIT: Sun Sep 16 22:12:40 2007: 4351 Xorg: client 3 rejected from local
host
AUDIT: Sun Sep 16 22:12:41 2007: 4351 Xorg: client 3 rejected from local
host
AUDIT: Sun Sep 16 22:12:41 2007: 4351 Xorg: client 3 rejected from local
host

Backtrace:
0: /usr/bin/Xorg(xf86SigHandler+0x81) [0x80bc151]
1: [0x110420]
2: /usr/lib/xorg/modules/drivers/nvidia_drv.so(_nv001038X+0x44) [0x2d6110]

Fatal server error:
Caught signal 11.  Server aborting

(WW) NVIDIA(0): Failed to free video decoder object
(EE) NVIDIA(0): Failed to tear down DAC


These lines don't appear in every Xorg.0.log.* nor in every gdm/:0.log.*, so
I
wonder...

No smoking guns with lm_sensors output, either.  Core0 Temp: +75F,
Core1 Temp: +75F, temp1: +75F, temp2: +88F, temp3: +77F,
fan1: 2884 RPM.

What else might I delve into?

Craig.
