My home PC was fine (I thought). I turn it on the other day and it says "Disk I/O error. The following file is missing or corrupted-Sample.sys- There is an error in your config.sys file on line 12. Device driver not found 'OEMCD001' No valid CD Rom device drivers selected. Invalid drive directory. Bad command or file name." ---What is all this? I tried rebooting, unplugging, etc. keep getting this same message! Please explain in plain English what do do as I am basically computer illiterate. Thanks for your help! It is Pentium II-266, Windows 95, BIOS version.
