I'm trying to install Windows XP Pro to a system with a Mach Speed MK8-939A mobo, AMD Athlon64 3200+ CPU @ 2.0 GHz, and 512 MB of RAM. I've tried this on three different HDDs now, with the same results on all three. The install itself goes fine. First boot from HDD (during install process) goes fine. After that, Windows will not boot unless I boot in safe mode. If I try to boot normally, I get the Windows XP logo screen, then the system hangs with a blank screen. I can, as I said, boot into safe mode with no problem. This is a new (to me) system. The previous owner of the mobo and CPU had no problems.
As a side note, I've tried installing SlackWare Linux on the same system, with slightly different results. With Linux, the install goes fine, but I get an "error loading operating system" message at boot, and it won't even try to load. Again, I've tried this on three different HDDs, with the same results on all three. Any ideas?
