BSD machine fixed!

So, I swapped a known working motherboard into the BSD machine.  It now works.  I also decided to use a quad core AMD AM2+ CPU that I had sitting around.  That's all I changed.

I'd originally thought the problem was related to the hard disk.  So, I decided the night before to disconnect the drives (it has two SATA drives), to determine if it were the real issue.  It still experienced the same symptoms after boot-up attempts, which told me it wasn't a hard disk issue.  I also swapped out the RAM with a known working chip with the same results when trying to boot-up.

So, either the the old CPU (a dual-core AMD...I forget the model) died or something on the motherboard died (or maybe there was a short somewhere?).  I left it running a live instance of Linux Mint, just to see if it stays stable over the next 24 hours.

Next, I need to reinstall FreeBSD (wondering if I should try some others as well, such as OpenBSD or Mint).  I wiped the drive, thinking that there was some corruption issue...shouldn't have done that.

System dead

OK. Apparently when the Ultra PS died, it may have taken the motherboard with it. The machine has been blue-screening ever since the PS replacement, just not as frequently as before.

I also noticed that the HSF on the Northbridge isn't working. When searching Google for issues with the Northbridge, I found that this is happening to others and that it actually signifies a motherboard failure. The Northbridge gets HOT and I'm assuming that over time, the heat has killed the motherboard.

This is the time to upgrade, I guess. I'll more than likely buy a new motherboard/CPU combo and it'll more than likely be a quad-core CPU that I'll be getting (Phenom):

EDIT - I ended up purchasing a

Foxconn A79A-S AM2+/AM2 AMD 790FX ATX AMD Motherboard

and a

Retail AMD Phenom II X4 940 Deneb 3.0GHz 4 x 512KB L2 Cache CPU

and basically rebuilt this system...it is SMOKING. I was gaming and installing game patches for another game AND XP updates, and only two cores were being used while two were idle!! I put 3GB of RAM into the system (I almost put 4GB but then realized that XP 32-bit would only see 3GB of it...time for a 64-bit Windows OS install, I think). I really should install some high-grade RAM, though, as I think I only have 667mhz installed.

I also bought a

BIOSTAR TForce TP43D2A7 LGA 775 Intel P43 ATX Intel Motherboard

for to replace the motherboard in the Pentium-D system...I'll use this motherboard and CPU to rebuild my old Sempron 3000+ system (I'm starting to stack up 'older' motherboards and CPUs).
