Do you have any more minidump files? The one you attached did not give a definitive answer.
Also, we note that you are still running XP with Service Pack 2. We here at TechSpot strongly urge that you update to SP3 if for nothing else security measures.
I have personally worked with people here in the last 3 months that their issue was because they still ran SP2. I am not saying this will resolve your issue but it is a good step to take.
Please tell us more about your system, i.e. make, PC or laptop, how old, hardware, OS, and security installed.
