Compaq Desktop Freezes and Failed to Function Properly

My Compaq desktop freezes quite often and failed to function properly. Here is the error that I have been getting on this machine: A FATAL EXCEPTION 0E HAS OCCURRED AT 0028: C0005338 IN VXD VMM (01) +0004338. THE CURRENT APPLICATION WILL BE TERMINATED. I don’t understand this because I have only the operating system running. Thanks in advance.
