OK. The M$ extended memory test ran overnight (~16 hrs, 22 cycles
completed) and no errors.
Ran Hitachi's Drive Fitness Test for 6 extended cycles (~3 hrs) - no
problems.
Opened the case and looked for swollen capacitors - found none.
Ambient temp on the kitchen table indicates about 21C (thermometer
reading, not chipset reading).
CPU? TEMP (Diode 2?): ~34C at idle and ~50C at 50% load
?????? TEMP (Diode 1?): ~46C w/ case open and ~56C w/ case closed
AMB? TEMP: (AMB?): ~33C w/ case open and ~45C w/ case closed
HDD TEMP(SMART): 38C~40C, mostly idle.
I wiggled a couple of connectors and cables around, and so far, no
freezes today.
I don't know what to say.

Good question - I don't know. I'll have a look after I've run the
extended memory test for a few hours.
Thanks,

Do all the caps on the mainboard look okay?

I'm experiencing random lockups 2~3 times per day. The display
freezes up, mouse frozen, CTRL+ALT+DEL doesn't work - I have to cold
boot to get it going again. CPU temp ~52C, HDD temp ~35C, amb temp
~42C (case is closed). There is no indication of overheating, the
Event Viewer is devoid of anything suspicious. There is almost no
load on the machine when it freezes. I run WHQL drivers from NVIDIA.
I'm starting to suspect the RIMM memory. I am currently running
"Microsoft Memory Diagnostic" found here:
(http://oca.microsoft.com/en/windiag.asp#top)
This being the only Rambus PC I have (or ever will have) I don't
have many options for hardware swapping to try and ferret out this
problem and the cost of replacement RIMMs is more than the rest of
the machine is worth.
Any ideas appreciated.
Jim
