Okay, to recap THAT project...
I bought a new power supply, the power supply tester and a new processor.
Tested the old PSU - registered HH on the PG value (I think that's "bad"). Everything else was fine. Replaced it. Made no difference.
Replaced the CPU and Voila.
So, I ended up replacing the mobo, PSU and CPU. Ouch.
NEW PROBLEM / Different machine
Does RAM just suddenly go bad?
Subject is an aging socket 939 AMD, MSI Nforce4. It started misbehaving (BSOD 0xA). On reboot, eventually gave me a keyboard error even though USB keyboard was plugged in.
Removed and replaced the battery on the mobo. Reboot with PS/2 keyboard. Boot to RAM Probe disk. Ram Probe goes absolutely nuts with memory errors.
So, it seems like the RAM is bad, but that just doesn't make good sense to me. And I can't really make sense of the Ram Probe output.
There are 4 sticks of RAM in the machine - 2x512MB and 2x256MB.
The machine had been running flawlessly basically 24/7 for YEARS.
I'd love some ideas.
