My Specs: CPU: AMD R9 9950x MB: ASUS ROG Strix B850-F Gaming WiFi GPU: MSI SUPRIM RTX5090 SOC RAM: Asgard DDR5 6000C28 64GB (32GB*2) PSU: FSP Hydro PTM PRO ATX3.0(12V-2x6) 1350W Monitor: MPG 272URX QD-OLED I installed a new PC and ensured the compatibility and electrical performance of each component. At the beginning, I installed the Windows 10 22h2 operating system and cleanly installed the latest Nvidia driver. In the default 60Hz mode, there were no problems. The status monitoring and parameters of GPU-Z and Nvidia app were perfect, but when I set the monitor refresh rate to 240Hz, everything became very unstable. When I adjusted the game screen settings in the game and clicked "Apply",or when I was playing the game, and when I exited the game to the desktop, the screen might suddenly go black, and then start to flicker frequently (black screen for about 3 seconds and then light up normally again, HDR words are displayed in the upper right corner of the screen, the screen lights up for 1 second and then black screen again, and it keeps cycling). Once this happens, I can only press the restart power button on the chassis to restart, otherwise it will keep flickering black screen and be completely unusable. This black screen flickering phenomenon is completely random and there is no pattern at all. For example, after saving the video settings in the game, the monitor suddenly starts to flicker black. After restarting, the same game can still run for a while, and there may be no problems for 2 hour, but it may start to flicker wildly when the game is just opened and running and it is still in the menu interface. Generally, this problem usually occurs when setting high refresh rates and game-related settings, and rarely occurs when the computer is turned on normally and low load. It usually appears when changing the video settings and saving in a full-screen large-scale 3D game, or when running the game. For example, it also appears in the TS and TSE benchmark tests of 3D Mark(but not every time). Sometimes it even occurs in the Windows desktop state just after the computer is turned on. I tried to turn off G-sync, HDR and other functions, and also tried to use the Nvidia-smi tool to monitor the stability of the pcie channel. I found that the NAKS_SENT number in "nvidia-smi pci -gErrCnt" increased(about 5), so I tried to set the motherboard interface to PCIE4.0 and found that the frequency of black screen phenomenon decreased, but it still exists. I also tried to reinstall Windows 11 24h2, but there was no obvious improvement. (P.S. I have tried all the latest driver versions, and 572.70 is slightly better, with less frequent failures. Other versions are very unstable, including the latest 572.83. I am sure that when the flicker black screen problem occurs, the system is in normal working condition, but the screen is black intermittently)
