New graphic card install on PC, after that PC wont boot

[tajrokun]

Hi I have a very strange problem.
It is about MB MSI h61m-p21 ( b3 ) and it run on HD5450 till now without problems, after I install a new graphic card to it r9 270x, PC power up and all is working except black screen on monitor and also I can't hear beep for boot up so it won't boot up. A ps unit is strong enough 650w Thermal take and I connect 2x 6 pin to graphic card.

As I can see MB is PCI-E 2.0 and graphic card request 3.0, but I read on this site that this is not problem and graphic cards 3.0 will work on PCI-E 2.0 slots on MB...

I spent a lot of time but can't find a solution any help will be desirable. Thanks.

Is old card still working?
Try booting with old card again - if it boots, new card is the problem probably.

Yes it is working. No it is not, new card 101% works without any problems. Something other is problem and I can't discover what.

Just now with old card I try to update to newest bios : https://www.msi.com/Motherboard/support/H61MP21_B3#down-bios
19.2 version is .exe and I put it into flash, run in windows, I get confimation on updating new bios, and a message that will continue after system is rebooted, after reboot nothing hapens... ?

Is this MB defected of what ?

Solved. In order to get this MB works with new cards like r9 270x and similar you must update to lastest bios. Problem was that bios on this board must be updated from DOS.
