I just put together a computer for my cousin, with the Asus P4S800D-X motherboard, P4 3.0 GHz processor, 2048 RAM. Now here is the problems. I CANNOT INSTALL WINDOWS XP!! When I first boot up it seems to hang just after detecting the hard drive (IBM 80 G). Then it boots from the setup disc says it is detecting my current configuration, then the screen goes blank for a minute or two before it ever loads setup. The first time I tried to install it told me the drive was unknown and the partition was not XP compatible. So I deleted the partition and created a new on. Same thing. So I go into the windows xp recovery console via the setup disc and reformat the hard drive. Then I went back into windows setup and NOW I was able to create a partition and it didn't say it wasn't compatible. It copies everything to the hard drive and tells me to reboot...and here is the problem...it WILL NOT GO BACK INTO SETUP TO CONTINUE!! If I set the hard drive as the first item in the boot list it tells me to go into the BIOS and select a proper boot device or to insert boot media into the drive and press any key to continue. I cannot do ANYTHING to get this hard drive to boot! I tried to install Win 2000 and in the blue setup screen it tells me Disk I/O error status 00008020. I know this hard drive works as I just took it out of his old computer and it ran XP perfectly! He has a smaller newer hard drive and I tried using that and it recognized the prior XP installation and if I try to boot from that it just tells me Disk read error. Can anybody help me with this? From what I can see the Asus P4S800D-X is notorious for this? This is my SECOND try at building this system as the first time he had a gigabyte mobo and it was defective so he decided to just go with a different brand. He is getting pretty frustrated as you can imagine.
