This is basically the same message I sent to ASUS tech support, but I haven't heard back from them yet (and was hoping maybe someone here has run into this and/or fixed it):
I have a new ASUS P4S8X motherboard with a 2.53Ghz/533 Pentium 4 processor. I also have a MSI 4600 AGP video card installed, a read/write CD-ROM/DVD combo drive, and a Western Digital 100GB drive (model #WD1000JB-00CRA0) with (2) 512MB Samsung DDR333 chips, a 300 watt power supply running on a known-good UPS. I originally had a lot of problems getting Windows 2000 installed; it kept failing during the first set-up screen with various errors. I changed the hard drive settings (disabled ultra ATA, set PIO mode to 4) for both the hard drive and CD-ROM drive, and that seemed to help. I was able to get Win2K installed. Now when the machine is under moderate hard drive and/or CD-ROM loading, the machine will reboot itself. Usually it will then display the standard screen that displays the hardware settings and fails with a "drive not found" error. If I power off and back on, I'm able to start Windows back up. I also tried leaving the machine overnight sitting at the Win2k desktop screen, and in the morning it was sitting at the "drive not found" error screen; the machine had rebooted. The machine has the Win2K drivers included with motherboard installed.
When I first had the problems with the machine (installing Win2K), I removed one of the 512MB chips and tried that. It didn't work, so then I swapped the remaining 512MB chip with the one I removed. That also didn't work. I swapped in a Viper 770 AGP video card (known good), and that still failed during the Win2K installation. I ran the Western Digital drive on another computer and didn't have any problems with it. It appears that the problem is centered around the motherboard itself. I have left the BIOS settings at their defaults, except for the harddrive/CD-ROM as listed above (which was necessary to install Win2K). Is there something else I should try?
I checked the Western Digital website and the drive I have installed (on the standard IDE port, not the RAID port) supports Ultra ATA100, Mode 5. I shouldn't have had to disable the ultra ATA mode in order to get it to work.
I also left the machine sitting in the CMOS screen overnight and it didn't reboot. I'm going to try installing Win98 tonight on a temporary drive to see if it still reboots.
Any ideas?
