So the problem started recently.
That means it is either:
a cap going bad.
oxidized contacts.
dust clogging the fans.
PSU is going bad.
something obscure.

Do the easy thing first. Clean your case, reseat all cards and  
memory modules
and check all caps while doing so. Any of them deformed? The 'head'  
going up?
Strange stuff around its feet? Congratulation, you need new hardware.

If you don't find a bad cap and the problem persists, get a new PSU.  
A good
one. Not big - most PSUs are oversized, but good quality. Anandtech  
has
something about psu's, so does tomshardware (most of their tests are  
rubbish,
but their psu tests are ok). If the problem goes away, congratulation!
If not, well, then report back ;)

I had a similar issue even when not running X. To be honest, I can't  
say I have a concrete idea of exactly what caused it. I simply became  
security-nuts and began wondering if it wasn't someone just toying  
with me; hardened my sshd config and installed denyhosts to monitor  
failed loggins. This was a month ago and my uptime has been perfect,  
with no restarts.
