Machine Checks usually mean a hardware problem.
Have you tried disconnecting all nut monitor, mouse and KB?

Please select one of the kernel panic reports and post it in its entirety. You have not included enough of the report to even determine what happened.

On the other hand, If you have crash reports from the failure of a single Application, please do not post more than the first screenful of information -- the rest is useful ONLY to the Applications Developer.
