Have you tried the system restore? From when you facing this issue?Do you have any related messages in system event log (run eventvwr.msc) ?

Can you say your system specs? If its old PC then, check in BIOS setup to disabled setting for PnP Operating system. Right clcik on error -> properties , you will see error details under description.

Have you reinstall motherboard drivers from CD that came with your motherboard? Same kind of some major issues going on with the virtual drive that is caused with the daemon program. Have you installed either daemon tools or alcohol ? pnp bios extension mostly is for daemon tools & it means its not properly installed.
