Question Gigabyte GA-H170-Gaming 3 Not Working

[barlowc]

Hello. I have a machine with a Gigabyte GA-H170-Gaming 3 system board which recently stopped working. I had updated the BIOS version from F5 to F22e in order to ensure support for the NVMe SSD that I was upgrading to. After the BIOS update, I successfully booted the machine using the old SATA III SSD. I then installed the new NVMe SSD and booted from it at least once. Then it stopped working. It doesn't even show the Gigabyte screen and give me the option to press the delete key and get into the settings.

When I power on the machine, the system board's red Ambient LED is on and the case and CPU fan both run. After a little bit it turns off and then back on. This repeats seemingly indefinitely.

I have removed the GPU card and don't have any other cards installed. I pulled all the memory too.

Any suggestions on further troubleshooting? Does it sound like the system board failed and I should replace it?

try taking the new nvme ssd out?

check with the old ssd and remove the new one with all hardware installed
which cpu are you using?
check the boot order

eventually reset the cmos

I don't have the new NVMe SSD installed. I only have the processor (i.e. i7-6700) and 4 memory modules installed.

I can't check the boot order because when I power on the machine, it doesn't even show the Gigabyte screen and give me the option to press the delete key and get into the settings. As such, I can't reset the CMOS either, unless there's another way to do it.
