Need help for BIOS updating

[Momas]

I got my Asus 7790 CU II 2gb today, installed it and PC won't boot. Fans are spinning on CPU, 7790 and case but monitor shows nothing. I looked around the web and found that BIOS update might help (http://superuser.com/questions/607027/system-wont-boot-gigabyte-hd-7790-1gb-oc-gpu-issue-or-corsair-vs550-psu-issue ; http://superuser.com/questions/661711/new-video-card-his-7790-oc-1gb-sytem-doesnt-boot). Could it help? I'm running:

CPU: A10-5800k

Mobo: Asus F2A85-V

RAM: 4gb x 2 Kingston HyperX Predator 1866mhz

PSU: Corsair CX430 (I think it should be enough for 7790)

 

If BIOS update could help, how to do it? Should I go with the latest update or should I first update to Version 5023 then to Version 5203 and so on? I should get my BIOS from here http://www.asus.com/Motherboards/F2A85V/#support?

 

Thank you for your help!

Reset bios try a CMOS or pull out the battery (I don't recommend taking out the battery ) but if u must, make sure all power connectors the noob will probably have a large connector and require 1 or 2 smaller such as 4 pins
