Please run a BIOS recovery, installing an older BIOS Version, you can start installing the 0559 BIOS version, https://downloadcenter.intel.com/download/22602/BIOS-Update-SIX7910J-86A-
Or trying a different BIOS version 0590,
Thank You for reccomendation i would really like to do that, but after removal of the battery i now have 10 seconds looping restart.
It means, fans start code 21 is on MB display and in about 10 seconds it restart.
It doesn't access USB or HDD or ODD.
i have tried removed everything except processor, but result is exactly the same.
Any other recommendations?
If after you tried the minimum configuration out side of the chassis, still this behavior, I recommend you to contact Intel® for support. http://www.intel.com/p/en_US/support/contactsupport. You can check the warranty status form the Motherboard at http://www.intel.com/p/en_US/support/warranty
Have you tried powering on with the Back-to-BIOS button pressed in?
Another thing you can try is to remove the new graphics card, reinstall the old one and see if this allows you to get into BIOS.
