I'd also say that memory problems would be highlighted when the machine 
is heavily loaded, not when it's "at rest". Consider disconnecting 
anything and everything non-vital. That means the cd/dvd drives, and 
expansion card excluding the graphics (natch), just one stick of memory, 
  and then do your best to replicate the problem. If the problem still 
persists then it is obvious it is either the cpu, mainboard, HDD, or 
graphics. The memory has been excluded because you checked it with 
memtest. The HDD can be checked using badblocks, try running that from 
knoppix or something  (f course reconnecting the cd/dvd).
It could be that ubuntu is trying to put the computer components in to a 
low power state and there is some incompatibility with that. Try 
removing the graphics drivers and using the generic ones. Just eliminate 
one component at a time.
