I have an AMD Athlon 1700+ system with an ATI Raedon 8500 64MB card running Windows XP. When ever I play 3D games the system locks up. The logitec joy stick doesn't work,nor the stirring wheel and pedals in the 3D games. After every lock up the CPU is at 130 degrees. Does any body know what could be wrong and how I can fix this. I would really appreciate this.
