The only driver that exist for a processor is the graphics driver for those that contain an Intel(R) HD Graphics controller.
Microsoft lists the processor to have a driver, as it is the way they make the Operating System to recognize the processor.
From the processor side, what we can recommend you is making sure it is being properly recognized by the system BIOS. Therefore, you may want to see if your motherboard BIOS is recognizing your processor as it should. For this matter, you can run run the Intel(R) Processor Identification Utility; you can find this utility here: http://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=7838
You can also run the Intel® Processor Diagnostic Tool to verify its functionality: http://www.intel.com/support/processors/sb/CS-031726.htm
Since the error in question is merely related to an Operating System issue, we recommend you contacting Microsoft* for further assistance.
Best option would be performing a fresh installation of the Operating System.
