Question No display to monitor.

[geofelt]

I recently went on a 2 week vacation.
My pc was working normally.
In preparation, I turned off my psu( Seasonic focus 650w) and shut down the pc.

When I returned, the monitor indicated no signal from the pc.
I have two monitors, a lg and a dell each is capable of hdmi or dp input.
No amount of fiddling with the onboard display controls worked.
Neither hdmi nor dp worked.
I tested each on a backup system using both dp and hdmi cables and both performed normally.
I tried alternate sets of dp and dp cables to no avail.
The pc with the issue has a asus b760-I strix itx motherboard as does does the backup.
I was careful to insert both the hdmi and dp cables fully.
The pc was using a evga GTX1050ti which has both dp and hdmi outputs.
I tried removing the gtx1050ti and worked with integrated graphics.

I get no bios screen at all.
I tried to load a usb stick with memtest on it, but to no avail.

At this point, I am planning to take it all apart, but since this is a small itx system, I am looking for anything I might have forgotten.

Try and reset the CMOS,

the battery connector seems to be under the heatsink, but there are two pins on a header labelled CLRTC. Try that.

If you're able to get display off the iGPU, it'd be a good idea to see if you have a BIOS update pending for the motherboard.

Thank you for the prompt response.
When I click on your link, I am directed to something called trade doubler.
The clrcmos area is tight and my eyesight is no longer good.
I may not have shorted it properly. no progress.
I am going to have to breadboard this.
I may need to upgrade the case(lian li Q08)
