a very slow 2004 laptop

I have a 2004 laptop with Window XP and it is very slow. I heard that if I remove everything and then re-install the operation system, it might get faster. But how can I remove everything especially the operation system?
Help!

• 嗯，是啊，現在的XP至少要1G內存。另外重裝前試試優化 -flywhc- ♂ (572 bytes) () 07/09/2010 postreply 07:28:50
