So was up early this morning and mucking around on my spare comp which is a Asus h110m-a/m.2 motherboard. Thought it was about time I checked if there was a bios update for it and I was way behind by about 5 versions so did the stupid thing and did the firmware flash through windows. Everything appeared to go well but now there is no post on turning it on just a blank screen.

I had a look around and it seems if you put a usb stick in with a bios on it it should let you flash it however it does not even seem to be accessing the usb ports.

Turning the system on it goes through its normal routine of spinning up all the fans and everything appears normal except no post and no display.

Tried clearing cmos and that sort of stuff but no difference.

Is there anything else I should be trying ??

First make sure to turn off the PC then plug your monitor to the graphics card display port.
See if that works if not.
Turn the PC off and try the integrated graphics slot.

It is import to turn the PC off as the bios is unable to switch display connectors like in Windows.

Normally which doing a bios update even through Windows it will do a update and verify. Of course always safer from BIOS. Or with a dual bios board which you can just move a jumper to boot into a stable bios.

If you think your bios is truly corrupted. You can normally recover it from a floppy or optical drive. I believe you have a modern AMI bios so you should be able to use a optical drive.

Try this first:

https://www.asus.com/support/FAQ/1012219

or (Same document)

page 7 of http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/PRIME_B250-PRO/E12583_BIOS_Update_EM_V3_WEB_20170614.pdf

If using USB Flash drive:

Rename BIOS File to H110MAM2.CAP as per page 17 of http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/H110M-A_M2/E11483_H110M-A_M2_UM_WEB_041816.pdf

If that dosn't work try below.

Get BIOS from: https://www.asus.com/nz/Motherboards/H110M-A-M-2/HelpDesk_Download/ #important make sure this is the correct board

Follow guide for: "For new boards with AMI BIOS core 8 (4MB)"

Hey thanks for the info, unfortunately none of that works as there is no activity on any of the usb ports, normally if you plug a usb stick in it will cycle though and at least light up a couple of times.

There is 5v supply to the ports but no activity during the power up process.

I don't have the support disc that came with the board well can't find it after a lot of searching and they don't offer an iso of the disc anywhere I can locate to try the cd route.

If the BIOS requires you to switch the graphics processor being used from within a BIOS screen then you need to plug your monitor into the onboard GPU port go into the bios and change the boot gpu to discrete graphics then turn off your PC change the plug from onboard GPU to discrete GPU and power on the PC

There is no graphics card in it as its just a testing pc , I have tried the 3 different display ports on the back with no luck.

Mspec:

.... no post and no display.

if the MB wont post , its never going to get to a state where you can reflash/recover via a USB/DVD etc

I know of instances where the completely wrong bios was on the website (other brands) . It happens & leaves the system trashed

Not helpfull , but you may need to replace that MB .
It is (in theory) possible to flash direct to the chip, if you have the gear to do it or can find a tech who will do it for less than what
the mb is worth

Yeah its out and gone and replaced with something else could not be bothered with it, as you said if you cannot post not much hope of getting any further with it better to cut my losses and move on. Was a cheap board as was just in a sandbox rig so not worried about it.
