R9 390 won't turn on

So, yesterday i was watching a YouTube video when the monitor suddenly turned black, it was working but it was black. I restarted my pc and the monitor was showing "No signal", i looked at my GPU and the fans weren't spinning. So, i switched the hdmi cable from the gpu to my motherboard, so i can use the integrated graphics of my cpu. After i  did that the monitor finally showed up windows' home screen. I opened Device manager and clicked on the "Video adapters" to update my gpu drivers, but i couldn't see my R9 390 there. Can someone help me with this problem?

If you are having Artifacts (strange colors or shapes) while just browsing or all the time that does indicate the GPU card is going bad.

Artifacts can be caused by Overheating, Overclocking, Driver, or GPU being defective.

I see that your motherboard only has one PCIex16 (16) slot the other is a PCIe16 (04) slot.

It is possible the PCIe slot is defective but most likely it is your GPU card since it is old. My bet is on the GPU card. If you can find another GPU card to install in the PCIe slot and it works that eliminates the Motherboard and tells you the GPU card is defective.

Can you post your computer's information including Make & model of your motherboard and GPU Card and Processor?

Sounds either the Motherboard or most likely the GPU card is defective.

Best way to eliminate the GPU card is by installing it in another computer and see if it does the same thing. If it doesn't then most likely it is your motherboard.

You can take it to a computer shop that will test the GPU card for free or for a small fee to find out if the GPU card is good or not if you can't find someone else computer to install it.

But first remove the GPU card and make sure the fan is clean and the contacts are clean and reinstall it and see if you have video.

How old is the GPU card?  Possibly the Thermal paste is very old and not preventing the GPU card from overheating.

Since you are getting video from the Integrated Graphics on your motherboard, in my opinion, the problem most likely is with the GPU card.

Thank you for your solution! My pc specs are:

  CPU - Intel i5-8600K 

  Motherboard - rog strix h370-f gaming

My R9 390 is pretty old but i don't think the thermal paste is the problem, cus the gpu never overheated, even when i was playing intensive games. I thing i forgot to mention is that sometimes (when opening a video from YouTube) i had screen glitches. I think  the pcie express slot might be the problem , or GPU might be dead.

My 380x died the same way about 6 months ago, the same way just all of a sudden nothing. I have seen many reports of the same thing with 3xx series going the same way. Likely it is just dead.
