The fact that it worked OK, the first few days, with FreeBSD and
Windows, may have been a Burn In test and now something in the HW has
failed or is failing. Or, possibly CentOS is utilizing the HW much
more robustly than the other 2 OS did?

I would suggest that you get a Knoppix Live CD, or, preferably, a
CentOS Live CD, and let it roll.

And, you get a Kernel Panic, after_ a_ few_ days, on CentOS. That
might indicate a Memory problem? Or, a Cooling problem?

Two banks of Memory (3 and 5) have problems?

If the RAM tests OK, suggest you swap the motherboard
