Hello everyone,
first I apologize in advance if my English is not that good

I will try to start from the beginning
Since I updated my BIOS version to the latest version on the GIGABYTE motherboard manufacturer's website (F23F version)
I started experiencing a series of different and strange problems

then when I restarted the computer there was no display on the screen...I had to disconnect the power from the computer completely for a whole day and plug it in and only then would the computer come on with a display on the screen.. but even then it would only come on once... when I restarted the computer there was no longer a display on the screen... a phenomenon very strangeI ignored the very fact that upgrading the BIOS version causes the problem... and I started looking for other solutions.... I thought to myself ok, maybe it's the power supply... so I went and bought a brand new power supply.When I connect the new power supply, the computer performs a LOOP loop of restarts for itself... and basically turns itself off and turns itself on again... and does not continue to the operating system

In the last few days, after I installed the new power supply I bought and when the computer was doing restart loops... there was still a display on the screen and I could enter the BIOS... in BIOS mode the computer could work for hours... but when it exits the BIOS and tries to continue to Any BOOT even USB or to the hard disk the computer just immediately does a loop of restarting...

Now after few days in the current situation... there is no display on the screen and the computer just does loops of restarting itself... I notice the fans working and then.. turning off.. and restarting itself again...

am quite discouraged and now I will list what attempts I tried to solve the problem but without success..

*I tried to connect the screen to the video card directly
*I tried to connect the screen to the video card built into the board
*I tried removing the processor and reinserting it..
*I tried to remove all the memories and leave only one memory and switch between them
*I tried to remove the battery from the board
*I tried to put the JUMPER on the board on the CMOS
*I tried to clear the contacts of the memories
*I tried replacing power cables. of screen..
*I replaced a new power supply with an ANTEC CSK 750 model
*I tried disconnecting all the connections from the board and all the SATA cables that are connected.
*I even tried to make sure that the new power supply I bought was really working... so I took another old computer that has a 500 watt power supply
And I connected to it the power supply of the new 750 watt that I bought and indeed the supply is working and there was a display and everything worked...
*Funny as it sounds I even tried replacing the motherboard battery


My specs:
motherboard - GA-H170M-D3H (gigabyte)
4X memory sticks of 8GB total 32GB --- memory model TED48G2400C16BK (DDR4 2400)
cpu - I5-6600
nvidia geforce 1080p
750W psu (ANTEC CSK 750W)

Appreciate your help in advance... I would love to know what else can be done?
 
if you cant roll back, try clearing it again. unplug it, take the battery out, hit the power button a few time to help drain any residual charge and the leave it sit for 5min. then put it back together and reconfig the bios. test the battery too, or if you have any pop a new one in. if its below 3v it could be giving your issues...

Hello everyone, a new update... I was able to clear cmos with two wires, apparently this time I did it well, but at the moment I get to the POST screen, and then if I press the BIOS entry option, I can stay there for an unlimited time, but if I exit the BIOS, the computer continues reboots itself with a display and then goes back to the BOOT loop until I enter the BIOS menu again, that means I'm back to the beginning only now if it's possible to see the BIOS

PLEASE SEE THE PICTURES I UPLOAD AT THESE 2 LINKS

(i just upload the picture to this post

Now the question is how do I continue from here? The computer loops with BIOS and cannot reach the operating system and cannot BOOT from USB

It's possible that your OS drive had Windows installed without UEFI so you might have to change the SATA mode to Legacy from UEFI.
When you flashed the BIOS it probably defaulted to UEFI.

hello Hello everyone, a new update and good news!

after i did clear cmos with two wires , one way with pc power on

and other way with pc turn of without the battry

so the only thing i was able to do its only go inside the bios or stay with the boot loop

so i was think to my self why not install again the last bios version F22f

i was installing again and the q-flash utility was asking to confirm and boom it boot to windows immediately

And I was so happy and excited that everything was working again... after 4 months

I really appreciate your help and many thanks
