Question Boot problems: the fans come on but no video. What's next ?

[okrobie]

The MB is an Asrock Fatal1ty H170 Performance/D3 with an i3-6100 and 32 Gb DDR3. Has onboard integrated video with DVI and HDMI (no VGA) ports. At the moment I have both modes connected to the same monitor with manually selectible mode. I have had it connected in all possible ways but the monitor always reports no signal. I'm using a known good EVGA 750W PS.

What kind of things should I be looking for?

Thanks

EVGA 750W
EVGA is the brand of the PSU while 750W is the advertised wattage of the unit.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model.

Might want to inspect the CPU's socket for any bent or broken pins. Try breadboarding and with only one display output port populated on the motherboard's I/O panel. Rams should be in slots A2 and B2.

Thanks for the help. I did find a few bent pins in the socket and straightened them as well as humanly possible. I do have a steady hand and good eyes despite my age (81). Never the less, I still have the same symptom so I will now go on to the breadboarding you suggested.

Ty with single ram module.
Try the module in different ram slots.

It would be surprising to bend a cpu pin unless you remove the cpu chip. I was going to tell you to look at the led while it boots but it seems I forget how fancy modern boards are. Even very simple led will give you a clue where it is getting stuck.

So it does appear your motherboard has a couple option you can try. First try the clear cmos jumper. If that makes no difference then try to remove the battery. There is also a jumper that lets you choose between 2 different bios.
