B2 Error on startup, Can't access bios

[Hurtta]

So, I decided to upgrade my computer a little bit since i was getting some lag on games like H1Z1. I bought a MSI GTX 960 4G graphics card.

I upgraded from an AMD Radeon HD 6770. Now on startup it has a white underscore on the top left of my monitor and it says B2 on the bottom right. It sits on the screen for about a minute and then boots to windows and everything is working fine, I can play games and do the usual stuff. I've had this problem for about 2 months now just browsing through forums looking for the answer but i haven't really bothered to fix the problem since my computer works normally after that 1 minute on the B2 error screen.

 

Also:

Processor: Intel I3 2120 (:D)

Motherboard: MSI Z68A-G43 (G3)

PSU: Cooler Master 500W

Did a google search and found some similar threads where people upgraded their graphics card and got a B2 error.

Seemed like most of them did a bios update on their motherboard and that took care of it.
