2 gigs is not really that bad if hes not playing newer High end games.
and Zeating your ram is underclocked right now then, you should be able to go into your bios and get it to running at the full 800MHz its rated for...
If you dont know how to get into the bios, soon as you start your comp it will say something like Press __ to enter setup (usually delete, F2, or F1)
once you get in there look around for a RAM clock setting and set it to the 400MHz setting, If you really dont feel comfortable doing it or think your on the wrong setting then DONT just ask us... but its really not as hard as it sounds
by the way i still think its ur psu
