First I would try removing your graphics card and use the onboard video and see if that get's your system to POST.

If removing the graphics card doesn't work, I would unplug everything you don't need to POST. So all your drives, leave out the graphics card you've already removed, only use one stick of RAM if you have more than one. Essentially the only thing that should be connected to the motherboard is the ATX power connector, the CPU / EPS power connector and your front panel switches / LED's.

Yes , when I removed the graphics card , nd it turned on just correctly .

Next to the 24 pin plug are some led's are any of these lit also? manual page 1-31

Code B2 is Legacy Option ROM Initialization. Try resetting the BIOS and see if this takes care of the issue.

Is my graphics card faulty ? Do I have to buy a new one?

 

[samwaz]

There are leds but they dont lit up near the 24 pin , how do I reset it , should I remove the battery and put my graphics card back on?

 

[bgunner]

Put it in before the reset. you push this button with the system powered off anyways. It will bring you to teh BIOS menu before booting so ensure that GPU is set as teh primary display device (PCI-e).

I just checked it just like a normal restart button , to reboot the system

If removing the graphics card allowed your system to boot successfully it looks like the graphics card is toast. To make sure, try it in another system if you've got one, or a friend or family members.

The led on graphics card lits up , fans spin everything but how can a grphics card die due to lightning , I have just one pc now

It's difficult to say why just the graphics card would have been damaged by a power surge. I'm not certain that it is bad, that's why I suggested putting it in another computer. If it works in another computer it could be either a BIOS setting that got messed up because of the power surge or something in the motherboard or CPU was damaged.

The other option would be to try another graphics card if you have one.

You could also try like bgunner suggested and reset your CMOS, the procedure is detailed in your motherboard manual. Just make sure you have the computer unplugged when you do it.

Nearly every graphics card that I've ever seen fail still had the fans spinning and the power LED light up. That just tell you that the card is getting power, it doesn't mean that it's able to initialize.
