Hi,
When during the boot-up does this error occur? Have you recently added or removed any devices or programs from the system?
Try going in through safe-mode. Does the error still occur? If not, then once you're in, go to Start, Run, then type in msconfig. What programs do you have running at startup?
Try choosing "selective startup", and check-off autoexec.bat and config.sys. Then restart. Is the error gone? If not, then try going back in through safe-mode, and this time, only take the checkmark off of system.ini or win.ini. Does it work now?
You might also want to try restoring the registry, if you haven't already done so. This might work, depending on how long ago you began receiving these errors. Boot to an ms-dos prompt, and type in:
scanreg /restore
Good Luck
