Why black screen why?

[Findiculous]

So after many years with the same rig components I have done a small upgrade to the GPU. Going from a 780ti to a 1070 as a temporary fix until im ready for full upgrade.

The 1070 was an ex mining card which has been working fine as far as I can see and works well in games.

 

However, at random intervals my dual screens will just completely go black. They are still on (green light instead of orange light) but there is no display. Sometimes this forces me to restart the computer and other times it restarts automatically (both times with the option to boot in safe mode as windows didnt shut down correctly).

 

I have tried a number of things including having the card fans on all the time (as the gigabyte card would turn off the fans if the card is below a certain temp) but to no avail. I did recently get 2 Displayport cables off amazon to fit the card into dual screen so i wonder if this might be the issue.

 

I put it to the forums. How would you fix?

The problem is as you stated, an ex mining card.

do the usual troubleshooting of checkingcables and connectors.

 

DDU your GPU drivers and reinstall them. and if non of this works you are probably unlucky and the GPU isnt top notch.

If nothing seems to fix it, also try underclocking your card. That'll help proving its instability.

Thank you for your answers. Strangely enough the problem has not repeated itself since I upgraded my OS from Win 7 or Win 10. I shall come back to these suggestions if the issue comes back.

Alright so the problem persisted and without any other option I replaced the Graphics card.

 

Everything fine for 24 hours and then the screen has happened again. 

The card is an Asus Strix 1070 8GB OC. So now going from Gigabyte to Asus but once again this problem repeated. I am still unsure whats going on. The issue only just repeated and I got the card on Sunday.

 

I removed all GPU drivers with DDU and reinstalled everything.

I have checked and the card is in correctly as is the power cable (as indicated with the LED being permanently on)

Its connected to my monitors via 2 Display Port 1.4 cables and  these monitors have never had issues in the past

 

Any suggestions?
