Intel processors are software and drivers independent, so the processor itself does not require any driver.
In this particular case I would suggest running the Intel® Processor Identification Utility to determine if the processor is being properly recognized by the system.
You can download the Intel® Processor Identification Utility at:
Also I would suggest running the Intel Processor Diagnostic Tool to determine if the processor has any issue:
This behavior that you are describing seems to be operating system related, so if the Intel® Processor Identification Utility and the processor diagnostic tool do not report any issue, a clean installation of the operating system would be a good idea.
I have the same problems, however I have run both tools and everything comes out fine with no errors. I am not having an operational issue with my desktop, I just see the same picture as the user who started the question, when I open my device manager and select the cpu.
