HELP!! Problems in XP instalation

Hi!

I’ve been trying to install Windows XP for 2 hours now on a PC with more then the minimum requirements. The problem is that upon the very first stage of instalation, where we have that blue screen detecting RAID and such….just before we even choose the partition……Well it justs stops the instalation dead on it’s tracks, it goes something FAT, Something NTFS and crash!!!Always, always on the same place….I tried several copies of XP on several languages, I even tried 2k Pro and it stops dead on the same place, the only SO I can install is crappy Windows 98.

I allready messed with every single setting on the BIOS and changed the RAM…nothing….Any sugestions? I’m desperate. I have to deliver this PC with XP in 3 hours.
