(SOLVED) Why RTX 3090 GPU Keeps Showing a Black Screen


Why Does My RTX 3090 GPU Keep Showing A Black Screen?

The reason your RTX 3090 GPU keeps showing a black screen is because the power supply is not sufficient, the GPU driver is outdated, or the PC is overheating.

 

Causes

  • GPU driver is outdated
  • GPU is faulty
  • PSU is inadequate
  • PC overheating

 

How Do I Fix A Black Screen On My RTX 3090 Graphics Card?

To fix a black screen on your RTX 3090 graphics card, you need to update the GPU driver and upgrade your PSU to supply sufficient power to the PC.

If your Nvidia RTX 3090 graphics card is causing a black screen, you don’t need to worry. There are a lot of reasons for this problem, but most of them are quite easily fixable.

 

Outdated Driver

The GPU driver allows the graphics card to communicate with the operatingsoftware and applications. If the driver is not up-to-date, this communication can be affected, leading to issues.

Regularly updating the software is necessary to ensure the smooth functioning of the GPU.

 

PC Overheating

This is the most common cause of black screens, and it’s mostly caused by dust accumulation. When dust accumulates, the heatsink, fans, and air vents stop functioning at their optimum levels. A good cleaning will remove the dust and ensure adequate cooling of the PC.

 

PSU Inadequate

Gaming requires a lot of power, especially a GPU like Nvidia RTX 3090. If the PSU cannot supply enough power to the PC, the GPU and other components will cause problems. The best thing to do is upgrade the PSU if you know the power supply isn’t enough.

 

Faulty GPU

A faulty GPU can be a big problem. The only solution is to replace the GPU. To find out whether the GPU is faulty or not, you can download a GPU health tester like FurMark to find out if the GPU is at fault.

Follow the steps below to troubleshoot the problem of the black screen due to Nvidia RTX 3090 GPU:

  1. The first step recommended by users who have gone through similar problems is that you enable debug mode and enable “prefer maximum performance.”
  2. To do this, go to the Nvidia control panel.
  3. Click on the help tab and then enable debug mode.
  4. Then go back and click on manage 3D settings.
  5. Under the global settings, click enable “prefer maximum performance.”
  6. To update the Nvidia RTX 3090 driver, go to the Nvidia control panel, click the help menu, and click on updates.
  7. Also, check if the PSU is adequate by multiplying the total volts and the total amps to get the total watts. If the PSU can’t supply the required watts, then upgrade the PSU.
  8. To find out if the GPU is faulty, download FurMark and run a stress test.
  9. Lastly, clean the heatsink, the fans, and the air vent of dust. This will ensure the PC doesn’t overheat.

Why Does My RTX 3090 Suddenly Have No Display?

To fix your RTX 3090 that suddenly has no display, you need to enable the debug mode and enable “prefer maximum performance” in the Nvidia control panel.

 

Causes

  • PSU is inadequate
  • GPU is faulty
  • GPU driver is outdated
  • PC overheating

 

I have highlighted the steps you need to take to solve the issue of your Nvidia RTX 3090 GPU having no display:

  1. The first step is to go into the Nvidia control panel and click on the help tab. Under this, you will find the debug mode- enable it.
  2. In the same control panel will be an option called “manage 3D settings”- click on it
  3. Then click on global settings and enable “prefer maximum performance.”
  4. If this doesn’t resolve the issue, then in the Nvidia control panel, click the help menu and click on updates to update the driver.
  5. Also, check the power supply. Calculate the total volts and amps of all the components and then multiply them to get the total watts. If the PSU can’t supply this requirednumber of watts, upgrade it.
  6. Download the FurMark software to check if the GPU is faulty by running a stress test.
  7. Lastly, clean the heatsink, fans, and air vents to ensure adequate cooling of the PC and prevent overheating.
