Sony Drku-500a Problem

I HAVE A SONY DRU-500A. IT HAS WORKED FINE SINCE I PURCHASED IT.
AS OF YESTERDAY…THE DVD BURNER WILL NOT CLOSE, IT KEEPS POPPING
OUT. i HAVE PUSHED IT IN AND HELD IT AND IT KEEPS GETTING A SIGNAL
TO OPEN. ALSO NOW WHEN I CALL UP MY POWER DVD PROGRAM…IT WILL
NOT RECOGNIZE ANY FORMAT AT ALL. IS THERE A WAY TO OVERRIDE THIS
SITUATION? I HAVE BEEN DOWNLOADING SEVERAL VIDEO PROGRAMS FOR
EDITING AND CHANGING VIDEO FILE EXTENSIONS…I.E. MPG TO ISO ETC.
I HAVE THE FEELING THAT ONE OF THESE PROGRAMS HAS TAKEN OVER
MY DVD WRTIER. I HAVE DELETED THOSE PROGRAMS FROM MY COMPUTER AND
RESTORED THE SYSTEM TO A EARLIER DATE BUT IT DID NOT CHANGE
ANYTHING. I WOULD APPRECIATE ANY HELP I CAN GET.
I HAVE USED CAPITALS BECAUSE MY EYESIGHT WILL NOT READ SMALL TEXT.
I KNOW YOU CAN CHANGE THE FONT…BUT DO NOT LIKE TO PLAY AROUND WITH FONT CHANGES.
THANK YOU FOR ANY HELP I MAY RECIEVE LATER.

Go to the device manager and uninstall the sony dru 500a and then reboot the pc and see if this corrects the problem.
