I upgraded to Win-7 64 bit and now my mouse cursor blinks with the busy icon about every 6 seconds. I also see the processor is running at a constant 4% to 6%.
When I had Vista the solution was to disable the HD Audio device and it solved the problem. Now this isn't working at all.
I also installed a new video card: ATI Radeon HD 5770.
Any ideas on what to try?
