I swear... computers are spying on us.

Not 60 seconds after I post about my wife's PC acting up my own PC
freezes. Upon reboot it complains about CMOS settings and crashes
within seconds after getting booted into Windows XP. I've reset my
CMOS to what it should be and the PC is fine now. BLECH.

Looking at my BIOS and MBM readings, my 12v seems high at 12.91v.
Other voltages a
5v = 4.93v
3.3v = 3.29v
-5v = -4.85v
-12v = -11.79v
Core0 = 1.79v (CMOS set for 1.77 and I can't change it)
Core1 = 2.58v and I don't recall what the CMOS reported (or if it was
even there)

PSU is a decent quality brand (which I can't remember at the moment).

CPU Temp is showing 54'C in MBM. CPU is an AMD TBird 1300.

It was quite warm today, but I did not use the PC at all while it was
hot outside, so that shouldn't make a difference.

Mainboard is an ESC K7VTA3 that I've had for months and have never had
a problem with.

- Is heat a problem for a PSU even when not in use?

- Many PSU's have one or more POTs to adjust voltages. Usually
adjusting one voltage messes up another (ie, if I lower my 12.91v down
to 12v my 4.93v would drop to around 4v - not good). Are there any
components in the PSU that I can replace to do the same the and
compensate for the difference? (ie, different value resistor, or use a
higher wattage or better grade?) I've pulled VLSI chips from
mainboards and resoldered replacements successfully, so soldering is
not an issue here.

...Definately looking forward to Christmas. Wife and I promised that
we'd replace *ALL* the computer gear at the end of the year. Too many
upgrades with old parts, new parts, questionable parts... Where are
they all now?



i've done some benchmark tests and varied vcore voltage and found that a few
hundredths
of a volt don't make any difference...so i doubt if you have a problem with
your ps

since both computers malfunctioned at the same time it's possible there was
a power surge of
some type.
maybe you should put the machines on a UPS
