1) After rebooting system, the following started to appear on screen:

C:\ Program~\ Compaq\ compaq~1\bin\Snbios2.exc
C:\ windows\Systems32\ Auto exec.nt. The system file is not suitable for running MS-DOS and Microsoft window applicarions.
Choose "Close"to terminate the application.

What is it and how to get rid of this?

2) WINDVD is working erratically, sounds and speeds are not clear.
The following appears:


"Unable to verify skins directory. Reinstall DVD"

When we try to reinstall the WinDVD/ CD version 3, the following appears:

"C:\window\Systems32\cmd.ex
C:\window\Systems32\auto exec.nt. The system is not suitable for running MS-DOS and Microsoft windows applications"
"a severe error has occured"


It looks like the two problems are related.

Please let me know how to proceed

Thanks
