Hello

I had a problem with the drivers of a mother board with Windows XP professional
To prove it with Windows 2003 STD I toward the same thing erase the whole hard disk and install it in my computer.
Now I want install windows XP professional again, but when erasing the hard disk and install XP it doesn't settle correctly.
With XP the beginning screen it is similar that of Windows 2003, even when Windows XP professional says when being loaded and non function neither the internet explorer, neither the restore system, etc.
The hard disk is Maxtor of 80 Gb, I proved format with the a software provaided by Maxtor, but every time that I install windows XP it settles bad.
I have to know how remove all the Windows 2003 STD components definitively, and install Winows XP again.

Sincerely
