Sorry for the Delay, I did ask for Help from others, but I think they are as confused as I am?
Firstly, you have a Machine that firstly you say is a No Brand, then say in another Thread is a Compaq Pressario tower as in here?

Compaq were taken over by HP and Most Machines set up will run Vista fine, but do not have Drivers for XP. I am just surmising to try to Help out?
I do not actuatually use Vista, but know from experience that HP/ Compaq always worked differentently to normal in Drivers and interchange Parts for many years, particularly in with XP and Vista.
if you have a Machine from them that was set up to Vista it is very difficult to get XP to run on that Machine because the Machine simply will not recognise XP Drivers and there are few availailable to match in. Hench your wish to reinstall Vista?
If that is the Case, please Post back.
There will be a way around it, Mate.
Edit. If I am right in what I say, contact Compaq/HP and get their Disks.
