SOLVED - safe mode boot stops on isapnp.sys

Faced this issue today. customer complained that he is unable to start his computer.

It goes past the BIOS screen and the screen turns blank.

When we tried to login to SAFE mode the computer stopped at ISAPNP.SYS

Finally we tried the 'VGA mode' and were able to get to the login screen

We logged in, did a virus scan, updated Windows and rebooted.

The computer works fine.
