>From my experiences, power supplys work, or they don't work. Its few and far
between when I see a power supply putting out +/- 1v on a 12vdc line. From
what was explained in the email, a power supply problem would be hard to
prove due to the fact that two separate cases displayed this problem. With the
same group of hardware.
Since the first explaination of this pointed at the CPU Cooler, I'd look at the
chip. I know of some CPU/Motherboard combinations that seem to work for awhile
but then have unexplainable brain farts. In these situations at our warranty
repair shop, we'd part the machine out, grab a new set of parts, and rebuild
the internals on everything. (testing the case/ps of course). It was cheap,
effective, and if it turned out to be a combination of items that just flaked
out after an overheat or something, we'd find it eventually.
I say for giggles, throw your wife's CPU into the same setup if it's possible
and see if it will run then. Then try slowly swapping parts from your wife's
computer into the affected machine. If you never get it to boot, do the
opposite and trade parts one by one into her machine. (AGP/PCI/ISA
conflicts aside). Eventually you will find the combination.
Good Luck,
