help installing windows XP Home

Hi,
I have an Asus laptop, it's about 7 or 8 years old. The only thing wrong is that it is very very slow so I want to do a reinstall. I thought a clean install the best way to go, I did a repair a couple of years ago with the 2 restore disks that came with the laptop but I feel a clean install is warranted now.
My question is, can I use the 2 Asus Recovery disks to do do this,and if anyone knows how would appreciate help.
I do have a Windows XP Home SP3 disk, it's a copy that I have had for some time. I was thinking that would be the best way to go but not sure.
thank you very much,
Joan.
