My guess your system is infected with malware. System files just don't go missing. At the very least your hdd is failing and thats the resaon files are being deleted. – Ramhound Dec 19 '12 at 12:13

This problem may caused by faulty RAM. Here there were two slots and I needed to test both.

You may get results like the following:

  • First RAM is good
  • Second RAM is bad

Taking both out and then putting the good RAM back in there was no error.

Put the other one in instead, or mix both, the error returns. This helps confirm that one of the RAM chips is faulty.

Testing this on another working hard drive using the same operating system showed the same error, confirming the RAM as the fault.
