Probably this is the worst situation, because it can happen any time. But their are many reasons and solution behind this, I'll tell you how to fix this error and what are the major causes behind it.

Before we start you should know about the error. The Desktop Management Interface (DMI) is a new method of managing computers in an enterprise. The main component of DMI is the Management Information Format Database, or MIFD (the DMI Pool Data). This database contains all the information about the computing system and its components.

Causes of error
At the time of boot system tries to update the changes to the motherboard BIOS settings, changes in hard drive or operating system, it can happen due to physical drive or any wire is removed from the system (Motherboard) and it may can happen sometimes due to high humidity computer gets freezes.

How to Fix it?

Method 3 :
Removing the "Clear CMOS" Jumper and resetting the system BIOS
Obtaining and applying a Flash BIOS Upgrade for your motherboard.

Method 5 :
Computer often freezes due to High Humidity and it may cause problem at boot. 
First start computer and keep it running for few minutes ( Keep the computer ON, even it is stuck at boot). Shutdown your computer and remove the RAM. Clean the RAM with an eraser (Don't touch the golden part of the RAM with naked hands). Install the RAM again and re-boot your computer. "Hope this will work", If you are still facing the problem keep the computer on few more minutes sometimes hardrive also freezes (This rarely happens).  

These are the most common reason for this Error. I had tried my best to help you, If your still facing the problem kindly contact to your system manufacturer. Method 5 helped me.
