Not quite back at square one as this recent test with another PSU has confirmed that the fault is not due to your PSU, so that has eliminated something else. The folder with the results when done with no Graphics card fitted was empty, but not to worry. The voltage readings for +12V and +5V are still way off so this has to be an inaccurate sensor.
My suspicion now is that the error could well be motherboard related. There is very little else I can think of that has not already been tested.
The only other thing I can think of is your chipset drivers, check these are up to date and all have been installed directly from the motherboard manufacturer's site.
And just one other possible cause would be a conflict of security software, so you could try uninstalling Eset and running Microsoft Security Essentials instead.
Follow this guide to uninstall Eset completely:
Eset Uninstall instructions
Install MSE from here:
Microsoft Security Essentials
Uninstall Spybot S&E, you must first disable Teatimer in the Task Manager.
Then install the free version of Super Anti Spyware:
Here
Spybot S&D is a bit of a resource hog and not as highly rated as SAS so that would be a good move irrespective of the problems.
If none of the above makes any difference then a motherboard fault would seem the most likely, but let us see a recent log from HJT so it can be checked for anything else. Please make sure you use the most recent version.
