Kid, if you ask me and have the money, in a month buy a whole new computer either powerd by a conroe or by the discounted dual cores AMD x2's... with a PCI-E Slot and a decet graphic card and ram.... would be a lot better, you'r cpu is not a very good one (an 1.8ghz athlon would be 20 times better I believe, lol)... you'r mobo is outdated and has been for the last 6 years now and I don't want to talk of you'r video card, it makes me sad.
Probably you could re-use:
Optical DVD Drive, Hard disk, keyboard, mouse, monitor.. about the rest, maybe charity can use it, probably not.. lol =x
I'm not trying to be offensive but the memory is probably 133MHz, the cpu is not very good although not that outdated and the mother board is so old that you should check under it if it has grown any beard.
Just a word of advice, It may came out a little offensive and I'm sorry if it did, its late here and im a little tired =x.
-Jo.
