I fresh installed win2kPro. My computer: 700Mhz AMD Athlon / 320 MB RAM / MSI brand MS-6195 ATX IR3(a.k.a K7 Pro) motherboard / chipset AMD 751 and 756 / AMI bios upgraded 12/28/00 ver. Everything worked fine on my computer which has an AGP Voodoo 3 2000 graphics card / serial Diamond Supra Express modem / CNET PCI Fast Ethernet Adapter. When I had win98 installed I also had a Diamond Monster Sound MX300 sound card. After installing win2kPro, I kept getting stop messages on startup. I wouldhave to restart over and over again to get it to finally start up. I used /sos and /noguiboot flags to trace the problem to the driver for the sound card. I removed it, and the computer operated fine. I searched for win2kPro drivers for the card and checked the HCL. Finally, I decided to get a new card. I bought a Creative Blaster Live! mp3+5.1 sound card and installed it. I got the same results. The computer runs fine and the card works, but if I restart the computer I can’t get it to come back up without going into safe mode and either uninstalling or disabling the card. The new card is on the HCL and has win2k drivers. I thought perhaps the slot in the motherboard was faulty, so I tryed the card in various other slots. No luck. I recieve the same stop message at start up. Occassionally, this stop message is UNKNOWN_HARD_ERROR. On rare occassion, I have recieved a INACCESSABLE_BOOT_DEVICE or KMODE_EXCEPTION_NOT_HANDLED. I have run chkdsk and it found no errors.
