 Topic: Help! No onboard display output from H170M-ITX/acPosted: 22 Mar 2016 at 2:44pm |

Hi,
I recently purchased a H170M-ITX/ac mini-itx board pairing it with a G4400 processor and I'm getting no display output from the onboard DVI and HDMI ports. I've already had the board replaced twice, but still nothing. The only way i can get a display out is by installing a PCI-Express graphics card. This is a brand new build and I cant seem to figure whats going wrong. I can't be receiving back-back faulty boards from Asrock. Can it be a problem with the processor? Or should i just switch brands? Any pointers would be appreciated. Thanks

Have you tried clearing CMOS?
Troubleshooting: 1. Clear CMOS 2. Use a PCIe GPU to access the BIOS and set "share memory" to anything other than "Auto" then save/exit shut down and remove GPU then test again. 3.check your CPU/Socket for damage/bent pins. |

Thanks Xaltar. I will try that.
But one point to note is that the first board that i setup had no issues for 2 days. The display suddenly went down around 20 minutes after booting into Windows 10. Now no matter how many times i change the board after that, I cant even see the POST screen with the onboard graphics.

So.. i tried all three steps. No go.
 Spent more than a week trying to get it work with the integrated graphics. Returning it. Never had a MB given me so many problems. PS: Something odd that i noticed with the PCIe Card. The VGA output on the card worked - but not the DVI. Played with all the bios options, but couldn't figure out why. At this point, it doesnt really matter, but was still very curious though.

This issue is different to yours EViL, this has to do with display outputs or possibly the CPU's iGPU where your system started out working then stopped.
@Noble I would RMA the board, by the sound of it there may be bent pins in the socket. Most manufacturers are good about RMAing boards with bent pins as there is no real way to prove if they were bent or not when you got it. Even if that is not the case an RMA will allow you to replace the board. Then if the issue persists with a new one the fault likely lies elsewhere. If you still have some patience left you can check the board for bent pins, on occasion it is possible to straighten them, especially if it is only the one. You will ideally want a bright light (sunlight is good too) and a magnifying glass. Good luck
