Hi everyone

So I've had a Radeon R9 390 GAMING 8G graphics card for a couple of years.
Recently when I was on YouTube for 15 minutes and the screen just turned all black but there was still a signal to my monitor since my monitor didn't turn off but the screen ALL black. The video was still playing in the background since my speakers still working (I can pause by space-bar but can't resume, I know it's strange).

Upon force shutdown/restart fixed the problem temperately but turned off again after 5 minutes. I reapplied thermal paste to CPU but didn't fix it. I changed monitor and cables such as DVI and DP, no change. I took out GPU and used the CPU graphics (the CPU intel HD Graphics), no black screen ever since and everything fine. So the GPU must me the problem or . . .

Could it be the power supply? Maybe it's become faulty
Over heating? yet the GPU isn't hot and normal fan speed
Or any other? please let me know

Thanks everyone

Another possibility is that the RAM needs to be re-seated. Remove each stick of RAM one at a time, clean the contacts, blow out the slot, firmly reinstall the stick, and repeat for remaining RAM.

You can do the same for the graphics card. Make sure that any PCIE power cables are firmly plugged in.
Try downloading and installing the graphics driver directly from http://support.amd.com/en-us/download .

Windows 10 updates device drivers. Every time this happens to me my secondary monitor goes black. And then I have to manually update the graphics driver again to fix it.

The same thing has happened to my audio driver. I suddenly had no sound. Upon investigation my Realtek HD Audio driver had been replaced with a generic Windows audio driver. So I went to Realtek online, and they had a Widows 10 driver ready just for this scenario.

I've been super busy no time for games. Now that I'm free, I re-seated the RAM and installed latest drivers and tried a couple of more solutions. Don't know what the problem was but everything is working fine now.
Thank You
