In my experience this is typical of hardware problems.  Most likely 
culprits are RAM, screen card, CPU fan, power supply.

I recently had a machine with a dual boot setup for Windows and Ubuntu.  
No problems with Ubuntu, but Windows started crashing regularly.  
Re-installation of Windows, disk defragmentation, RAM test, etc. nothing 
solved it. In the end it was the screen card, which somehow only 
affected Windows and and not Ubuntu.

Same occurred to a friend of mine.  Upgraded from Win XP to Win 7.  No 
problems with XP but as soon as he upgraded the machine hung regularly.  
In his case the cause was the RAM.

It's conceivable that a problem could also appear in some versions for 
Ubuntu and not in others.

I suggest you start with a RAM test and have a look at /var/log/syslog 
for clues.  Good Luck!
