I have a problem, I replaced my motherboard after it died and now during startup I am getting the STOP ERROR inaccessible_boot _device. I am running Windows 2000 Server and would rather be using XP. The STOP ERROR hits while trying to load windows. It is recognizing all of my memory and hardware on the startup but crashes right after the windows screen pops up. I would love to format the c drive and start over but when I boot from a startup disk it tells me that the C drive isn't there ("invalid drive specification.") I am fairly new to the tech world and would like to fix this myself. THANKS for any help
