Budda,
CMOS or the setup for your computer can be accessed by pressing one of the Function keys while the computer is booting up. Usually it is F1 but on some computers it is the DEL key. It should tell you during the boot up screen which to use. If your computer has a floppy drive and if another computer has a floppy drive you can format a system disk that allows you to at least see directories on the drive. You will need a DOS primer to know how to step through the commands. usually by typing c: you can get to the root directory on the C drive. Then type dir/p and you will get a directory listing one page at a time. Hit any key to advance and you will see if all is still on the drive. If there is nothing on the drive then you may have to format C: and rebuild. I think you may have other problems though.
If you suspect a sound card problem, you might disable it in the CMOS setup. Save the settings and then continue to boot.
There are some really nasty viruses out there that wipe the boot sector of the drive. That is where the turn on info for your computer resides. It might be recoverable but you will need a good virus program to do that.
