Boot Loop of 10s after updating BIOS

[eugenez]

My Machine:
Windows 10 64 bit
Intel® Core™ i5-6500 3.2GHz 6MB LGA1151 BX80662I56500SR2BX
Kingston 16GB 2133MHz DDR4 CL13 DIMM HyperX Savage KIT OF 2 HX421C13SBK2/16
Gigabyte GeForce GTX970 4GB GDDR5 PCIE GV-N970IX-4GD
Arctic Freezer 7 Pro Rev.2 Intel/AMD K0909/ DCACO-FP701-CSA01
Asus B150MPROGAMING
Thermaltake ATX 2.3 Smart SE 80+ 530W SPS-530MPCBEU

I did check all my components and they all function properly, for example when I took both ram sticks my PC stopped boot-looping and started beeping which indicated correctly for missing ram I took out for the test until I forcefully turned it off with a power button.

I tried CMOS battery removal various times with up to +1hour removal as well as the 2pin reset so it won't help as it can't due to my bios being the newest version and CMOS battery and 2 pins do not revert/downgrade but simply reset the basic time/date etc.

My questions are:

• 
  Is my motherboard dead and has to be replaced or I can still fix it?

• 
  Want to give a try to make a usb with downgraded/older version bios but don't know how as didn't found a detailed up to date tutorial/video with all required files.

• 
  Maybe there is another button I missed like Delete f2,f8,f12 TAB which could get me somewhere in that 10s frame time? Do I spam the button or press and hold at boot?

Thanks for any help in advance!

Spam the delete and f2 button to get into bios. Flashing them is pretty easy from there on. Just make sure you get the right bios b
