Since we moved house the MCE PC has kept crashing, the most I’ve had it stable is about an hour which is a bit of a pain when trying to watch television of an evening!
I finally got round to doing some diagnostics on it (there were 22 kernel dump files ready for Windows Error Reporting). WER and the Action Centre aka Checking for Solution to your problem didn’t have a clue what was the cause.
I downloaded Windows Debugging Tools and despite using the 32-bit WinDBG on a 64-bit image it was able to pick up an error code of 124 which is a hardware fault. According to various overclockers forums it generally indicates a lack of core cpu voltage.
I’ve now upped that to 1.3v in the no touch configuration menu page in the BIOS, same with the memory – changed that to the middle voltage value then the highest and still no system stability.
The helpful chaps at www.sevenforum.com suggest a real hardware error if the system is not overclocked. However, there doesn’t appear to be an easy way to identify which specific hardware component is at fault.
As an aside, the windbg configuration for the symbol server I use is:
