roll back

[Overclocker 0]

I'm experience slow performance on my new installed XP by 'clean install'..compared to previous Windows I've use (WinME and Win2000)..my specs are as follow

 

Athlon XP 1500+ (1.53ghz@1800+)

256MB DDR Samsung

MSI KT7 TUrbo 2 Pro RU

ASUS V7100 pure (geforce 2 mx)

Creative SB Live!

40GB Seagate hard disk..

 

What is my problem cause by anyway?..I'm thinking to roll back for Windows 2000 as it has given me a top notch performance in computing experience..any opinion? thanks in advance..
