Ahhh didn't know about the rating. I thought it might just be inefficiency from aging, or maybe the 80+ PSU really are more efficient (not just a marketing thing).  The just replaced PSU is a new Antec Signature 650W, and the one I've just put in is an Antec NeoHE 430W from 4 or so years ago.

I am using a 64bit OS now.  

uname -a
Linux mythtv 2.6.32-25-server #44-Ubuntu SMP Fri Sep 17 21:13:39 UTC 2010 x86_64 GNU/Linux

Originally I was using Mythbuntu with the PAE kernel (loads of lockups), but a few weeks ago I switched to Ubuntu Server 10.04 x64, but the freezes continued.  No freezes since upgrading BIOS, but now I've had 2 random restarts.

This is a Gigabyte GA-H55-USB3.  What processor are you using?
