I have a new dual core X2 4400 processor which is effectively two CPUs running together, so one handles one task and the other another. That and more memory solves the problem.

Thanks lads , I've got it sorted now by 1) switched to btcomet 2)reduced setting on up load and 3) Only use the f'ucker when I'm not using the pc .
