Hello All, I recently purchased an AMD Athlon 64 3000+ CPU on an ASUS K8V-SE DLX motherboard. I pulled a DVD burner, and 120 gig HD and a 160 gig hd from my old machine to use on this new one. I also purchased a Radeon 9800 PRO video card. I placed all these devices in the machine, and it boots to the bios without a problem. I can go into the bios setup, all master/slave relationships look fine. However, I cannot install windows! I am able to boot to the Windows XP Home CD. I deleted my old windows partition from the 120 gig drive, had the CD reformat and run a fresh install. It works to a point, the format completes, it does a premilinary install, then it restarts. However, when it tries to re-start setup, I get a Windows STOP error 100% of the time. The message reads something like "A problem has been detected and Windows has been shut down to prevent damage to your computer." It goes on to suggest some solutions, none of which really apply to me, especially considering this is a fresh install. The 'Technical Information' it lists is: "STOP 0x0000008E (0x00000005, 0x805185B2, 0xF86A5D28, 0x00000000)" The second drive (the 160gig) I am using has never had an OS on it, and I really really do not want to lose the data on it, so reformatting the drive is not an option. I have tried reformatting the 120 gig again several times, and I get this same result every time. What could be causing this? Shouldn't everything be normal if it the bios load normally? What should I do? Should I try a differant video card? Should I buy a new hard drive? Can I fix this from the Windows repair console? Is it memory related? I have 512 MB DDR PC3200 that was bundled with the barebones system at time of purchase. Not sure what the manufacturers name is. Thanks so much in advance. I just don't understand why this keeps happening because its a fresh install... Thanks so much!!!
