[wplug] Another OT buggy-hardware post

[Brandon Kuczenski]

Thanks for everyone's suggestions, and thanks especially to those people 
who can accomodate for the fact that I don't seem to be able to read
(Chet) or Google (Jonathan) properly..

The power supply is a new premium low-noise one which is more recent than 
the crashing started happening, so I think it's okay.

I dd'ed memtest onto a floppy and ran it overnight at my underclocked 
speed (1250 MHz).  It ran for almost 8 hours and reported no errors.  I 
rebooted at the proper clockspeed (1666 MHz) and was about to leave it to 
run all day when my computer spontaneously shutdown between 20 and 25 
minutes in.

Incidentally, memtest reports the processor as a Duron, not an Athlon XP. 
/proc/cpuinfo reports:
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 8
model name      : AMD Athlon(TM) XP 2000+
stepping        : 0
cpu MHz         : 1222.637
...

My conclusions: heat and the video card are clearly not the problems.  I 
think the memory itself is ok.  There are no jumper settings on the mobo 
for either CPU or Memory voltage -- just about the only user-configrable 
settings are the clock multipliers -- so the problem must be the mobo or 
the cpu.  Based on comments in this thread, I'm going to buy myself a new 
processor.

Thanks for everyone's help and especially their patience.
