its ubuntu, it looks very similar to windows and has only basic programs like a word processor, mozilla firefox, and AIM. thats all he wants it for. ive made a couple of bucks from people by simply defragmenting there hard drives and deleting the extra startup processes, they think its magic.
Does your ram have red heatspreaders? If so, have you tried running your ram at Cas 2? I bought 2 gigs of patriot from newegg (cheap as hell too) that was rated at 2.5@200. It will do 2.5 @240 and 2@220 with a little more voltage 2.7-2.8. I have a list I found with the speeds if you're interested.
i have the "budget" ones with blue heatspreaders and they are listed aas 3-3-3-6 but on the sticker it says 2.5-3-3-6 so go figure im running them at 2.8 V @230 on my evga board on my old asrock they would only go to 2.5-3-3-6, 2.6v@200
