Which component is failing the bios boot up ?

[logicandreasoning]

My system is giving errors and bios settings are reset on. Every boot.
It started happening after windows 10 but once i am on desktop.. there's no crash on any thing.
It only happens during bios test start up.
Which hardware component can be faulty ?
Is the motherboard dying?
I tried clearing cmos , cleaning mobo and ram with degreaser , changing hdd cables .. changing mobo battery .
Can't figure out which hardware is the root cause.

It resets bios settings everytime to defaults.
Sometimes win 10 boot gives inaccessible device error.
Sometimes there's no display on bios.
All temps are normal. Browsing , copy paste , hd gaming , all run perfectly fine , hdd health is also perfect ... No crashes no nothing. Even temps are fine !

Mobo. P8b75 ml x , asus.
Gpu 1060 6gb gtx asus.
Ram corsair xms3 4 x 2 gb @ 1600 mhz on xmp
Psu corsair vs 650.
Wd 1 tb green .@5400 mhz
Cpu 3470 i5 @ 3.2 ghz

Have you changed the CMOS battery? If not I would do this first.

Sorry....I missed that.

So sometimes you make it to Windows and sometimes no?

What are the errors the BIOS gives you?

Bios doesn't give any error... that's the weird part. it just displays the Bios info on the american megatrends screen and asks to press f2 for bios setup.
