Question:

I am experiencing screen flickering and PC restart issues with my RTX 4090 ROG OC White graphics card (Driver 551.23 WHQL). The problem occurs randomly during normal desktop or browser use. Sometimes the screen goes black for 15 seconds and then the PC resumes, other times the PC restarts completely. The problem does not happen when I use the basic Windows driver instead of the Nvidia driver. It also seems to be less severe on Windows 10 than on Windows 11. I have tried using different power cables and changing the color depth setting in the Nvidia Panel, but nothing has helped. My card is running at stock settings, with no overclocking or XMP enabled. My RAM is 4800MHz. My PSU is EVGA SUPERNOVA 1000G XC ATX3.0 520-5G-1000-K1. I have attached a video of the screen flickering issue. My previous card, RTX3060Ti, did not have this problem. Is this a known issue with the RTX 4090 ROG OC White card or driver? How can I fix it? Any advice or suggestions would be greatly appreciated.

In this article, we will try to answer these questions and provide some possible solutions for you. We will also explain what might be causing these issues and how to prevent them from happening again.

There are several possible causes for screen flickering and PC restart issues with RTX 4090 ROG OC White graphics card. Some of them are:

• Faulty or incompatible driver: The Nvidia driver for the RTX 4090 ROG OC White graphics card might be faulty or incompatible with your system or monitor. This can cause instability, crashes, and display errors. The driver might also have some bugs or conflicts with other software or hardware components. The driver version 551.23 WHQL, which you are using, might be one of the problematic ones.
• Insufficient or unstable power supply: The RTX 4090 ROG OC White graphics card is a very powerful and demanding device. It requires a minimum of 850W PSU and a 12-pin power connector. If your PSU is not powerful enough, or if your power cables are loose or damaged, the card might not get enough or consistent power. This can result in performance drops, artifacts, and shutdowns.
• Overheating or thermal throttling: The RTX 4090 ROG OC White graphics card generates a lot of heat, especially under heavy load. If your cooling system is not adequate, or if your case airflow is poor, the card might overheat and throttle its performance to prevent damage. This can cause stuttering, lag, and screen flickering. The card might also shut down or restart the PC if the temperature exceeds a certain threshold.
• Incompatible or faulty monitor: The monitor that you are using might not be compatible with the RTX 4090 ROG OC White graphics card, or it might have some defects or issues. The monitor might not support the resolution, refresh rate, or color depth that the card is outputting. The monitor might also have some problems with the display port, HDMI, or DVI cable that connects it to the card. This can cause signal loss, distortion, and flickering.

You can also try to use different power cables or a different power outlet. If possible, you should test your card with another PSU or another PC to see if the problem persists.
• Improve the cooling and airflow: You should also monitor the temperature and fan speed of your RTX 4090 ROG OC White graphics card. You can use software like MSI Afterburner or HWMonitor to check these parameters. You should make sure that your card is not overheating or thermal throttling. You should also make sure that your case has enough fans and vents to provide adequate airflow. You can also try to clean the dust from your card and case, or apply new thermal paste to your card. You can also adjust the fan curve or the voltage of your card to lower the temperature and noise.
