There should be a STOP code near the bottom, and it looks like something like this.
STOP 0x000000A or something like that. Or at the top, it might tell you the conflicting file. Pleas tell us
If that doesn't work, go into safe mode. Depending on what version of Windows you have, it differs.
Go to start, then run. Type in eventvwr.msc and press ok. That should bring up the event viewer.
Take a look in the application logs, and see if any errors occurr round the time the error happened. Then take a look in the system log and see if there is any error there. Please tell us the error and the event id.
If nothing, go into safe mode and DISABLE the virtual drive. Now put on Daemon Tools or something and load the virtual drive from that and see if it causes any errors.
Try all these solutions in order.
