Tiff,

First off stop being a tight twat!!! That PC you have is a piece of junk!!!

Personally I would do the following.........

Scrap the whole fooking thing and build a proper matched specification. If you havent the spare brass to do that, then do the following....

Increase your RAM to a MINIMUM of 512mb, prefferably 1GB.
Buy either a x800PRO or X800XT graphics card or the Nvidia equivalent
