i'd say best bet would do a system replace, but keep the hard drive and dvd rom if it has it..

you an buy my computer from me ! i will ship and everything, its got all original packaging , custom built, totally pwns at any game ( yes even crysis on high ) its the bomb diggity!

and cheap!
if your ram is ddr2 800, you can slap it on my mobo and have even more ram, if not i wouldn't because it would bottleneck my gaming ram >.<

but if interested just pm me. all parts have lifetime warranty, never registered them to my home so i could give you em and you have warranty still! don't go buy a new system and spend thousands! buy a working used but excellent condition one!
pm me for more details, specs, prices and w/e else you want to know

and im a trustworthy guy.. we all know this.. so don't be alarmed.
