I Am Getting CMOS Checksum Bad Default Configuration Used. Show Me Its Solution.

2. The BIOS was updated incorrectly. It may be because power is lost during updating BIOS.

Follow the steps given below to solve this problem:

Method 1. BIOS change/semiconductor (CMOS) to complementary metal-oxide setting can cause serious problems, and it can prevent your device from starting properly. Microsoft cannot guarantee that problems causing by BIOS/CMOS setting can be solved. Changes to settings are at your risk.
