Screen started to go on and off for a split second.

[Hasaryo]

About 2 months ago, 1 week after I bought the system I bought about 1 month ago, the screen started to go on and off for a split second. To explain, my monitor turns off and on for a split second. This problem sometimes repeats every 2 weeks, sometimes 3 times a day. It doesn't happen every time I turn it on or after a certain period of time. My video card lights are on as far as I can see through the glass of the case when the screen goes out. I don't think it's the monitor because I was using the previous system on this monitor. Here are the solutions I have tried so far:

1. I changed the HDMI cable.
2. I did a BIOS update.
3. I disconnected and reconnected the GPU and PCI power cable.
4. I updated the GPU driver.
5. I stress tested the system, no problem even though the temperatures rose during the test, the problem recurs whether the system is hot or cold.
6. My monitor does not have DP input, I bought a DP - HDMI cable today and I will try it soon.
7. I changed the pci16 option from auto to gen4 in bios settings.
8. I made the output color format ycbcr422 from the nvidia control panel among the options I read here before.

Thank you for your help in advance.

I forgot to mention that I connected my speaker to the monitor's audio output. I get it from the video card via HDMI and from the monitor, and when the screen went off for a split second, the sound went on and off. Maybe there is a problem with the video card HDMI output, but the card is a new card.

System specs;

RYZEN 5 5600, ASUS PRIME B550-M K, GALAX RTX 4060 Ti, FSP Hyper Pro 650W 80+, HyperX Beast 2x8 GB DDR4 RAM

Had similar issue, I did every swap of HW possible and software uninstalls it came down to the Cablemod custom PCI-E 6 pin cable breaking contact upon thermal expansion, when I used the supplied EVGA cable it solved the random boot and shutdown issues. Find another cable and try it. I do custom PC builds for a living. The reboots and issues were totally random even occurred when making a new boot SSD or when gaming. See my pic the white cables to the GPU were the issue.

Mine would as crash in BIOS or idle desktop, I figured it out after seeing a customer touch his six pin PCI cable and it caused his build to reboot also. Cable mod are nice aesthetically but are flimsy in their lightweight design. The ATX pins wobble inside the Cablemod male connector resulting in a broken connection which will cause the GPU to lose power and reboot the PC. Have not had a 41 error or power reboot error in 2 yrs since replacing .

thank you for your reply. i plugged it into a second pci cable that was in the psu but my problem persisted. by the way, there is no reboot shutdown problem when the screen goes off on my computer, even the gpu lights continue to light up. i will try with a new monitor soon. i hope the problem is with the monitor.

Do you get a warning in the windows event viewer?

 

[Hasaryo]

only 1 kernel power 41 (63) but it might be because I recently turned off my pc from the power button because my computer froze.

Mine would go black screen and reboot with this error randomly, came down to pci cable to GPU. Contact your PSU maker to see if new cables are compatible.

Just had an issue with the display port; a little silicone oil on the connector seems to have fixed that issue.
