More like too little...  Dude's computer crashes and has a glitchy power
behavior after he tries to use the opengl subsystem...  I'm guessing he
might be able to get away with bumping up the voltage to his ram (cheap ram)
and chipset (cheap mobo), or his powersupply isn't up to the task.

I've just build the latest generation of PC's for my family (and the wife's)
and all the power supplies I kept squirreled away did me no good.  We've
migrated to the dual core / > 2gb ram range and during burn-ins I'd see the
same sort of behavior.

I got by wiith a couple of my 350+ watt jobs and some tweaking, but the rest
I had to buy fresh.

In related news I have plenty of SATA power adapters I guess I wont need...
;)
