Went in to start up my desktop. Received message saying that windows was not shut down correctly, it had frozen while shutting down. Attempted to restart computer in each one of the modes. In safe mode it listed a page and a half of drivers then rebooted and went back to same error page. In safe mode with networking the computer froze. In safe mode with command prompt received the following line and then nothing - multi(0)disk(0)rdisk(0)partition(1)WINNT\system32\ntoskrnl.exe In Last known the Windows XP logo appears then back to previous screen. Starting Windows normally gives me a black screen. I have gotten into a blue BIOS screen and the only event listed is a CMOs/GPNV Checksum bad, set everything to default and nothing has worked. Is there a way to get DOS to come up so that I can do a check disk or reinstall Windows? I no longer have this computers xp disks; I have another computers XP disk. If I reinstall will I lose all my saved info?

Hello sicvic, If you have any Windows XP Installation CD ( not any type of recovery CD that may have been bundled with your computer/laptop ), you should give your CD drive first priority in the boot sequence of your BIOS's configuration page. Next you want to load the CD in and start up your computer. The Windows XP CD will take a minute to load ( screen will be blue ) and then, on the first user interaction screen, you'll given the option of pressing "R" to access the "Recovery Console". From the "Recovery Console", select the path of your OS ( usually number 1 ), then type in your administrator password ( if you don't know your administrator password, you might have not set one so just leave it blank ). Now, you'll be able to perform diagnostics and repairs in a dos-interface ( type "help" and press enter for a list of commands ). The first thing I suggest you do is scan the disk for errors by performing the command "chkdsk /r". If you are still unable to access your computer after the tasks have finished, please post back and give us some more detail about the events that happened before your computer malfunctioned. It's always nice to have some feed back after things are fixed =)

Thanks for the help. Tried your suggestion and didn't work but took the case off since we recently moved and found out that a piece on the mother board was loose which caused the issue.
