   HI All

H110M-HDV R3.0 loses usb and video output.
Running Intel i7-7700, one SSD, 8GB Crucial RAM.

I bought this used, it was working...brought it home, blew some dust off and hit go.
No video output.
Removed the GPU card, no video from onboard.
Tried reseating everythig, then there was a result from the onboard GPU.
Tried the GPU card - all ok.
Went back to onboard - ok.
A couple of restarts - lost mouse and keyboard.

On restart, sometimes these have worked.
When it worked, halfway through a Win 10 update, I noticed the keyboard and mouse had become unresponsive.
On restart, there is a mouse light flash, but ther is no further response from mouse, keyboard or display output, on HDMI or VGA.

Any suggestions or experience of this issue?

	Maybe check if all the CPU socket pins are okay, since a lot of stuff comes from the CPU. And did you try a different PSU? When in BIOS check the CPU temperature, if it is rising fast, ik could be related to the CPU cooler. Also don't overtighten the CPU cooler, besides Noctua a lot of brands go way over the intel specs, causing the CPU and socket to bend under the pressure. So check if your CPU is not bent. When a cooler is fglast on the CPU surface, and cannot move aroud, the pressure should be sufficient
	Kind Regards

	Hi and thanks This machine was running fine, i just blew some air over it and then these issues appeared. So - I re-pasted and reseated the CPU cooler. Did not move the CPU. Tried various RAM options and restarted. I have just tried another working power supply. There is still power to the board, and GPU, fans are spinning but no output to vga, or mouse and keyboard. The front power button light is on. Cannot enter bios as there is no display output from either the onboard or GPU card...
