I have an AMD Athlon 64 and of course XP. Thing is my computer is VERY slow now. I mean click on an Icon, wait for it.........THEN it loads. Word is slow, most programs are slow. I can crash it easy if I want. My Puter isn't that old, 2005 100 Gig hard drive and could run Doom 3 Pretty well. Any help or any way to make it speed up?
