I just bought a CPU my current CPU is i3-4150 now, I bought an i5-3570. I would like to know how to update BIOS? my BIOS Version/Date based on my System Information is American Megatrends Inc v1.4 2/20/2014. I'm just new from upgrading a PC.
 
Well, MSI show you how on website for the bios

and looking at what is there, I would actually suggest you do it - https://www.msi.com/Motherboard/support/h81m-p33
As you on version 1.2, there are 9 bios versions since yours. You only need the last one. They all improve the stability of the PC.

which version of windows are you running?
as you probably want to update the chipset and Intel management engine interface driver, they are on the drivers tab
Chipset driver is under System & Chipset drivers
Intel Management Engine Interface is under Other drivers - it helps if the version of this is about same age as BIOS.
