    Check all pins for any dirt or slight bend, but it points to a dud CPU.

    So I had this issue when I bought a MX4940 off ebay. I returned it and got a MX4940 from another seller and issue was resolved. I say it is the CPU.

    I bet you got my returned CPU lol, that would suck.

    edit: I just checked my history, it was MX4930 not a MX4940 that I had the issue with.
