ok i got into the bios and have check the order and it floppy, hd, cd so i can't see why that isn't working now?? Is there anyway to setting bios to default? If yes would that work or could it have been modified before i purchased it? or could one of my parts blown? Thanks for you patience Sampson, i really appreciate you trying to help any more ideas??

i can't get into safe mode so i put back in the old burner and it still reads the same error? I have been searhing for a solution pretty much all day and one site i was at said that it possibly has set the bios to load form it rather then the C drive? Im not very computer hardware smart so can anyone tell me how i can check that? Or if it could even be the problem? If anyone knows what i can do i would be very thankful

i tried to install a dvd burner into my PC, so i turned it off at the powerpoint, opened it up and took out the old cd burner and replaced it with the dvd burner. Now the computer won't even start, after the win 98 splash screen i get this message "While initializing device SHELL: Cannot find or load required file KRNL386.EXE The file was not found press any key to continue" then when i press a key it switches itself off. I thought maybe about re installing windows, so i inserted the boot disk but the computer won't read the a drive?? anyone have anything i could try to get it working :(
