I have found that if I upgrade my X850 PCI-E from Catalyst 5.2 to any driver more recent (like the 5.10 for example) that my motherboard will occasionally beep whenever I use a 3D accelerated program. I have tested both DirectX and OpenGL programs and they both produce this annoying beeping sound. I have upgraded all my motherboard drivers in a vain attempt to stop this. Any help would be appreciated.
