Bad hardware
Memory-related issues commonly cause this issue. If you've recently installed any new memory into the computer, we recommend it be removed to verify it's not causing the issue. If, after removing the memory, this issue no longer occurs, you have either bad memory, or it's mismatched with memory currently installed in the computer.
If you have not installed any new memory into the computer recently, it's also possible that the memory currently installed in the computer is bad.
