I did not take the sticks out. So far all of my tests have been software-based. Sorry if that was not clear. My A+ training/cert., for what it's worth, taught me to start with software and when that avenue has led to either nothing or more questions, then move to hardware.

That's why I generally go straight to hardware, because it only takes about 15 minutes to check all the hardware possibilities, and if its not hardware, reformatting is pretty much the stock solution. Not that occasionally it cant be fixed faster, but on average reformatting is faster than troubleshooting software issues.
Reformat, if that doesn't fix the problem then its your PSU.
Swap out your PSU, if that doesn't fix the problem, reformat.
I think I'm gonna have to go with the later as being faster and easier. No amount of software is ever going to tell you if your PSU is failing. If it was bad memory it woudl manifest itself in other ways, not shutting down, more like crashing, blue screening, just plain locking up.
My bets are the PSU or your CPU is overheating.
As far as the PSU there are 3 things that can go wrong.
1. It could just be bad. They go bad sometimes and act goofy.
2. It could be under-rated. Maybe it always was and as it aged it can no longer put out as much power what with all the internal dust those things build up.
3. It could be OVER-rated. I see people all the time putting a 1000W power supply in a system that only takes 250W and then wondering why it doesn't run right. Switching power supplies REQUIRE a minimum load to operate properly. Again, just because it always ran before doesn't mean its guaranteed to keep doing so as it ages.
From the symptoms you described I'm betting its either malware or the PSU.
It finally did it again today. I'm starting with the PSU and moving from there. I have a strong feeling it is the power supply.
I found a power coord leading to my THX speakers was barely in the power strip. It appears that it had been pulled at some point and almost pulled out of the socket. I can imagine that if this plug was barely in that it could possibly get pulled out briefly and then get moved and make contact immediately after. This could definitely cause a surge and/or fault. It did not trip the power strip but this is probably b/c it's surge protector is designed for large scale surges. My PSU, however, is designed to pick up extremely small variations in voltage but large enough to filter out common voltage spikes/drops in the line.
Perhaps my PSU was just doing its job by shutting down the computer. If it happens now then I will begin to look inside of the system. But this power plug is extremely suspicious.
It's highly unlikely that that would cause a surge significant enough to cause a shutdown. Surge detection is more geared towards local lightning strikes than a loose connection in a piece of equipment plugged into the same wall socket.
Hey I know next to nothing about electricity and hardware but I think you are being wildly optimistic with that last thesis Bubba.
