its a compaq presario 6000

couple years old

pentium 4 cpu 2.0 ghz
256 ram

40 gig hard drive and a while back i put in an additional 80 gig harddrive

both are close to full but i intend on getting an external drive and dumping the memory of the desktop to it, then running dumb virus scans on it before proceeding

it moves real slow right now

im going to be using it mostly for making music so i know im going to want to get the ram to 1.0 (or better) hopefully

any problems you can foresee with this? anything else i should consider? suggested places to get ram? should i take it somewhere or can i just do it myself?

im obviously trying to save money cuz i could just go out and buy a new tower if this is going to be either too frustrating or expensive

thanks!
