Question

Hdmi no signal

Sep 17, 2017 2:27PM PDT

All I could think of that cause the problem is the high-speed cable I recently bought on Amazon, but that doesn't sound reasonable. I used that new cable only for 4-5 hrs on Friday. However, my monitor got no hdmi signal on Saturday when I tried to boot it on. When I switch to onboard graphics card of my motherboard, my monitor got back hdmi signal. Afterward, I had tried the method which unplugs the PSU power cord and held the case power button for 30 sec to 1 min, however, my monitor still got no hdmi signal.
Motherboard: ASRock z75 pro3
GPU: SAPPHIRE Radeon R9 280X
Memory: 4x G.SKILL DDR3 2400 4GB
PSU: EVGA SuperNOVA 1000 PS
CPU: i5 2400

sounds like a "driver" problem

Make sure you have all the drivers loaded for the alternate video card you want to use. It should have been supplied with the card.

My monitor got no signal If I connect the monitor to 280x, therefore, I have no way to access the AMD driver. Even though Using onboard couldn't start the driver either because the software cannot detect any graphics hardware.

If your not getting a bios splash screen then I doubt it's a driver issue.

If your monitor and video card support a different connection...vga/dvi/dp try that.

I kind of had the same problem...

I had an Nvidia GTX 1050 Ti graphics card and it displayed the same issue. I installed and reinstalled all the relevant drivers. The fan of my graphics card did work initially but then, that stopped working too.
In my case, it was an hardware issue. I had a 3 year warranty on my card so I claimed that.
