Hey guys I was looking for some help on my current situation.

ive had to replace my motherboard in my pc twice and i didnt reformat my pc on either time...come to find out now it may be why ive lost soo much cpu power and got just an over all "sluggish" feeling. im going to reformat my pc tonight...well try anyways but i only have the Windows XP recovery cd and im not sure if i will be able to get my pc back to normal using just that after the format. I have some information about how to create a bootable windows xp install cd using the files from the recovery cd but once again i really dont know if any of this will work. Im really not in a hurry to go buy another copy of Windows. Any help would be great! Thanks
