Hello guys,

I have a rather irritating issue with my new desktop. Only started over the last 3 days.

Whenever I switch on my desktop for the first time of the day I can't get any display to show on my monitor, its as if the cable isn't plugged in (no signal). Went through the standard checking cables etc and nothing. Rebooted desktop via button and then it worked. Thought it must have been a one off.

Now over the following few days whenever I boot up my system I never get a display show unless I boot my PC then reboot it via the button.

I've no idea why this would be.

Any ideas please?

System spec (including PSU make/model)?

This is the build, I got OCUK to build it too.
The monitor is Acer ED242QRAbidpx 23.6 Inch FHD Curved Monitor (can't find product link on OCUK website)

Could be bad psu not giving full juice on 1st try but giving full juice on 2nd.

Anyway I can test this?

Thanks for the support guys.

Best way is with another known good PSU.


Erm also, the 56 is pretty power hungry.... you could check if the power leads to it are seperate or daisy chained.

I'll check this tonight, I guess it would be best if they're separate? I'm not very techy when it comes to the components.

A friend has also just suggested the BIOS may be defaulting to onboard graphics when booting, something else I'll need to check.
 
From what I can see, single cable going from psu to gpu. Booted up for the first time today, same issue - no display. Powered down, switched off mains power to psu, went through startup process and boom, display showing.

So it's still only the first time booting it up after its been left for a while.
 
Have this regularly with HDMI to two different tv's using two different cards over 3 different cables down the years.
My fury did it, vega did it connected to a 4k 49" LG and my 1080ti also does it to a new LG b8
Cables chopped out from multiple different suppliers, latest one is a 70 quid "high quality" one (5m)

I have ran out of care now, its only occasionally it does it.
 
Amd application is now detecting an error. "the system has detected A link failure and cannot set the requested resolution and refresh rate. Your display might not support the requested resolution or there may be an issue with the cable connecting the display to your computer." - this error has also disappeared this morning, I did a driver update last night, perhaps it was a moment of failure. Resolution is fine and displaying at 144Hz

I guess the next step would be to try a different cable on first boot tomorrow?

**update**

Booted for first time today, same issue. Cable is being detected but no display. Tried moving cable for gpu to motherboard, no difference. Tried hdmi instead, same problem. Tried hdmi into my main TV and same issue there.

I used to have similar issues with an old KT7A board. It was the bios. Swapping out the CMOS battery used to fix it. Eventually there was a bios update that fixed it. Although it wasn't a universal problem with the board.

Very similar symptoms. Intermittently wouldn't complete booting, it would power up, but no video. Got worse over time.
 
Overclockers are arranging collection of my system so they can test it. As it's not until Monday I'm going to do a fresh install of windows over the weekend if I manage to get the display to work at any point, least that way I can rule out software issues.

I've checked online and it seems like a common issue but no certain fix. Pretty annoying though.

Does that help? Looks like a cable lopped then from gpu to psu.

Yeah, that looks daisy chained. It's best to have 2 totally separate cables to connect PSU to GPU. Check if that PSU came with any extra PCIe power cables (don't use ones that don't belong to that same PSU unless you know what you're doing because the pinouts can be different).

Ah thanks for confirming. Overclockers are getting the system back next week to check it over, I'll let them mess with that if needed. Don't want to break any warrenty.

Thanks for the advice though all, learning quite abit from these forums :)
