Fix – Intel CPU uCode Error

by Abhishek Bhatnagar on March 15, 2009



One of our readers Rahul submitted problem saying:

When I start pc it show error message "Intel CPU uCode error" show on startup and show f1 to resume. When i press f1 window start without problem, but how can resolve this issue.


Most of the errors which are detected by the BIOS are displayed at the boot screen with an options to Press F1 key to continue and ignore that error. This error is one such error. There can be several reasons for this problem including:

  • Problem In BIOS Software
  • Compatibility Problem Between CPU and Motherboard

In this post we discuss the solution to Intel CPU uCode Error.



A bug in BIOS software can really goof up and show error like Intel CPU uCode Error. So in case you are getting such error, first thing we recommend is to upgrade the BIOS software to the latest version available online on the manufacturer’s website.


BIOS upgrade will solve the problem in about 95 % of cases. Rest 5 % can be because of hardware incompatibility like the FSB frequency of the Motherboard and Processor not matching properly, making one of them running in slow mode.


To check for hardware compatibility, check the user manual of Motherboard and see what models of CPU it supports. You need to ensure that the CPU you are using is fully compatible with the Motherboard that you are using,if not, then you need to replace on of them with the compatible component.
