(SOLVED) Why RTX 3070 GPU Keeps Showing a Black Screen

Why Does My RTX 3070 GPU Keep Showing A Black Screen?

The main reason why a RTX 3070 GPU keeps showing a black screen is because the power supply is insufficient, the GPU driver is outdated, or the computer is overheating.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  • GPU driver is outdated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 3070 Graphics Card?

To fix a black screen on your RTX 3070 graphics card, you need to update the GPU driver and upgrade your PSU to supply sufficient power to the PC.

 

PC Overheating

Computer overheating is one of the most common reasons for a black screen. This usually happens when dust accumulates on the pc, making it difficult for the PC to cool itself efficiently. All it requires is a good cleaning to remove the dust from the air vents, heat sink, and fans.

 

GPU Driver Outdated

The GPU driver is responsible for communication between the computer’s operating software, the graphics card, and the applications. If the driver is outdated, this communication doesn’t happen as smoothly as it should.

A simple resolve for this is to update the GPU driver.

 

Faulty GPU

A faulty GPU is just unfortunate. And there isn’t much that can be done except replacing the GPU. However, you can run a stress test to ensure that the GPU is faulty. There are many GPU stress test softwares online that you can download.

 

Power Supply Unit Inadequate

The PSU supplies a certain output; if this output doesn’t match your computer’s requirements, you will have problems. A simple solution is to manually calculate how much power your PC requires.

You can multiply the total volts with the total amps of all the PC components to get the total watts. If this doesn’t match the output of the PSU, then you’ll need to upgrade it.

 

If your Nvidia RTX 3070 graphics card keeps causing a black screen, then follow the steps below to resolve the issue:

  1. The first step is to enable the debug mode. You can do this in the Nvidia control panel under the help tab.
  2. The second step is to enable the “prefer maximum performance” mode. This can be done by clicking the manage 3D settings optionin the Nvidia control panel and then clicking the global settings.
  3. In the same control panel, you can click on the help tab and then on updates to update the Nvidia RTX 3070 software.
  4. If this doesn’t work, then check the PSU. You can calculate the total required watts by multiplying the total volts and the total amps of all the components.
  5. If the PSU can’t supply the required watts, you will need to upgrade the PSU.
  6. Cleaning the PC is always a good idea. Overheating can cause a black screen, so clean the heat sink, the fans, and the air vents to allow for efficient cooling.
  7. Lastly, you can confirm if the GPU is faulty by downloading stress test software like FurMark.

Why Does My RTX 3070 Suddenly Have No Display?

To fix your RTX 3070 that suddenly has no display, you need to enable the debug mode and enable the “prefer maximum performance” mode in the Nvidia control panel.

 

Causes

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

 

Follow the steps below to troubleshoot the issue of your Nvidia RTX 3070 having no display:

  1. The first step is to enable the debug mode. This can be done under the help tab in the Nvidia control panel.
  2. The second step is to enable “prefer maximum performance.” To enable this go into the manage 3D settings option and click the global settings where you can enable this mode.
  3. In the Nvidia control panel, you can also update the software by clicking the help tab and then clicking updates.
  4. To check whether the power supply is adequate, you should multiply the total volts and the total amps of all the components to get the total watts.
  5. If the power output of the PSU is less than the total watts required, then you need to upgrade the PSU.
  6. To prevent overheating, clean the PC;the heat sink, fans, and air vents must be cleaned of dust to allow for efficient cooling.
  7. Lastly, to determine whether the GPU is causing the problem, you need to download a GPU stress test software like FurMark and run a stress test. If the GPU is faulty, then change it.
