Software Loader 3 Error on Booting Up Windows 2000 PC

Hi. I need help with my Windows 2000 computer. Every time I try to boot up my computer I am getting a message telling me that there is a “Software Loader 3 error”. Then the computer just stops running. I tried to boot the computer using Safe Mode but I cannot even get to that point.
Does anyone here have an idea what the error message is all about and how I can fix it?Thanks.
