i have 2 systems built with asus p4c800-e mobos and both have sata hard drives. both systems are built correctly and the drives are detected properly. but yet i can never seem to install windows xp on these systems and it took more than one try on my lga rig. the setup files are always loaded but the first screen never comes up to let me install the os it always freezes and after a million tries i was able to install it once on one of the systems but then i cannot boot from the hard drive it constantly wants to install the software again. i dont know whats going on but after putting together the 2nd rig and all the hardware being brand new it cannot be a hardware problem at all i have swapped ram, video cards, hard drives, cd roms, and checked bios temps and i cannot get the systems to work at all. i also have 2 copies of xp one student copy and one legitimate copy i bought for myself and they both behave the same. i have been frustrated for days and the manuals have given me no ideas so i turn to ask you guys to help me out in any way you possibly can. thanks
