I have got Windows 8.1 freshly installed on my computer, and it works fine. In most cases, it manages to find and install drivers itself without much intervention from myself. However, there is an exception and as you can guess from the title, it is the processor!
Anyway, today I finally found a solution at:
http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/error-code-52-intel-i5-processor-driver-64-bit/3a46fd52-a798-43b5-9506-8c451980a567
It seems the problem is not new as the solution is for Vista.
Microsoft's knowledgebase:
Device Manager does not show updated processor information on a
Windows Vista-based computer or on a Windows Server 2008-based computer
Before following through the article (for method 2), I disabled automatic driver installation. To do this, I did the following:
1) Opened Devices and Printers.
2) Right-clicked my computer's device icon and clicked on Device Installation Settings.
3) Set the option to No Let me choose what to do -> Never install driver software from Windows Update, but kept the bottom checkbox checked.
After this I manually assigned a driver to the processors in the device manager one by one. I chose
"Processor" rather than "Intel Processor". This seems to solve the problem.
Hope this helps.
