I have a homebuilt system and I'm trying to do a fresh install of Windows XP with Service Pack 2 because I caused the prior install to freak out when I upgraded my processor, motherboard and video card all at once. I was stuck in an infinite loop during the Windows install and suspected that my non dual channel memory was burned out so I bought two 1 GB sticks of DDR400 dual channel (crucial). Now when I try to resume setup I get the above error and it continues to reboot continuously with the same result.My prior build was an Asus K8U-X (socket 754) w/AMD 64 3200+ and Radeon 9800 Pro AGP with 768 MB DDR400 single channel memory.My current build is an Asus A8S-X (socket 939) w/AMD 64 4000+ and ATI x1650 PCI-e graphics card with 2 GB of DDR4-- dual channel memory. The HDD in both is an 80 GB IDE.Any ideas what could be wrong? I suspect the HDD now.Thanks, but I tried removing a gig of memory and the same error happened. Also, since I still haven't finished the install of Windows, Microsoft's hotfixes are no help. I have Windows XP Pro, not the Media Center or Tablet versions.
