Dead sensors or what ?!

I have strange problem , so uefi bios is showing wrong temps like -1 for MB and for cpu -5 and FANS rpm is showing to MAX all time , like 6533 rpm or so , but they not.

Also i cant fully shut down my system , it stuck after HDD is off and i have to  switch off by myself

Also in A-TUNING i cant regulate fan rmp or see right voltages and temperatures .

And yes i have the latest bios version  (1.20) to fully support G3258 .

Tryd to reflash bios , same bugs.

And when its been off ,  i power it on it dont boot , just black pic , i have to press restart button and then it boots up.

 

SPEC:

 

4gb ddr3 ram 1600mhz running at 1333mhz

Pentium G3258 

Asus HD 6670 video card 

Corsair CX430 power supply

And this asrock  B85M-DGS

Im using windows 10 , but thats ok , because before it was working fine.

 

What can i do to fix this nightmare ?

If I was having those issues I would RMA the board or at the very least contact customer support. It sounds to me like its a BIOS issue, but it could be a component failure on the board.
