Hello, I'm looking to upgrade my pc to make it run faster. I thought about starting from scratch and building my own, but I wouldn't know where to start and what types of disasters I would run into. Right now I have a compaq presario, running win xp home w/ a 2.4 ghz intel celeron processor w/256 ddr sdram memory w/60 Gb of hard drive + cd+rw drive. I'm looking to have at least 3.0 ghz processor and would like to use that new Hyper Threading?Is there any other hardware etc. I could use to make my pc any faster? Thanks for the help.
