nice thank you i can update my tower sooner and for less $. just to be sure can i use my xp os (40gb hd) or will i have to reinstall or is it one of those things that might work or might not?
You're welcome. Since you are changing motherboards you will likely have to do a clean install of XP. You can try just using the old HDD, but the new motherboard's drivers are different, and since your current XP doesn't have them, it may not be able to start.
