Hi,

I am building my daughter a PC for school work and some gaming out of old parts from home and the office. Components listed below.

MOBO - Gigabyte z370m d3h LGA1151
CPU - Intel Core i7 9700
HDD - 1TB Seagate BarraCuda ST1000DM010, 3.5" HDD, SATA III - 6Gb/s, 7200rpm, 64MB Cache, 8.5ms, NCQ
PSU - Gigabyte P650B 650w 80 Plus Bronze Power Supply , Black
RAM - 2x8GB Cors VENG LPX DDR4-2666
M.2 - 512GB Intel 660P M.2
GPU - GTX1080 or GTX1050ti
Cooler and fans are stock

The problem I am having is that the computer seems to boot up fine, the fans spin the mobo board light comes on but I can't get any signal to the monitor, I have listed the things I have tried below. Any help would be greatly appreciated, I am starting to lose hope in my basic knowledge.

- Swapped out the motherboard for another
- Tried RAM one at a time
- Tried different known working RAM
- Disconnected everything, reset CMOS, took SMOS battery out etc
- Tested power supply with a multimeter
- Test all cables and swapped for know working cables
- Tried computer with different monitor and cables
- Tried 2no. GPU's
- Reseated CPU with fresh thermal paste
- Took all components out and put it back together

The other motherboard is an asus H310M-AR2.0

A couple of obvious things to try, have you plugged the additional power into the graphics card ? either 6 pin or 8 pin connector, maybe 2 of them.
Also the CPU should have onboard graphics, have you plugged the HDMI cable into the motherboard HDMI output (IO Portion) or the Graphics card HDMI output (assuming you're using HDMI)
Failing that you could try removing the graphics card and see if it posts using the CPUs onboard graphics.

Only asking as sometimes I make silly little mistakes when im loosing the will to live with technology.
Its all I could think of that you've not already tried.
The only other thing I could possibly think it would be is the CPU itself.

Thank you for the response.

I have tried removing the GPU and plugging HDMI into the IO output and still no signal, unfortunately.
It may be the CPU itself

That's quite old; have you replaced the CMOS battery?

You need BIOS version F11. Do you have an 8th gen CPU you can try? Speaking of the BIOS, that board has a dual BIOS so have you tried the other BIOS?

Thank you for the response.

I haven't tried changing the battery but the board was working in the machine it was taken from.
How do I access or switch the BIOS when I can't get any display? Is there another way?
Looks like I might need to scope out another CPU to try.
 
Have you tried removing the gpu and tried the on board Intel gpu by plugging HDMI cable directly to the motherboard ?

Only two things it can be at this point. Cpu + monitor?

Cmos battery won't make any difference, it'll still boot without a battery.

I'd remove everything not essential, one stick of ram, one hdd, no gpu (assuming the cpu has built in gpu). If you have the old cpu, that'd be my first thing at this point - assuming you've tested the monitor.
