Installed new mobo, now can't install Windows XP. Help needed!!

Hi guys,

I recently bought a new motherboard for my Dads PC. I got the ABIT NF7, but now after installing it, I can't install Windows. I havn't got a bootable CD so I've been using the Windows XP startup disks. I've used two different sets but the PC freezes in exactly the same place with both sets, and that's right at the end (when I put in disk 6, its reads it for a second, then freezes) when the installation is about to start. I know it's not a prblem with the startup disks as I have used them before. I've also tried installing Windows 2000, but again, the PC freezes just before the installation starts.

I don't know what is wrong, so if you guys think you know or have any suggestions, could you please tell me as I'm getting a little ****ed off here. . .

I'm using a Athlon XP 1800+ with 512MB DDR400 PC3200 RAM just incase you need to know.

Thanks

Manni
