Occasionally the GPU signal disappears and I need to restart my computer.
Hello,
Here are the details of my setup:
BenQ 28 Inch 4k monitor EL2870U
Fractal Meshify 2 mid tower case
PSU Silverstone 1000w modular
RTX 4080
MSI A Pro Z-490 Mobo
i7 10700KF
32GB DDR4 2 x 16gb @ 3200MHZ
Coolermaster Hyper 212 CPU cooler
Samsung 970 EVO 1TB nvme m.2
Samsung 980 500gb nvme m.2
WD 1TB hard drive
3 x 140mm Arctic P14 front intake fans
2 x 120mm Arctic P12 top exhaust fans
1 x 140mm Arctic P14 rear exhaust fan
I’ve been facing random black screens for some time, mainly when using my RTX 3080 10GB during the pandemic. The issue still happens occasionally, sometimes once a month—screen goes black, fans increase, and I have to power off. Audio stays unaffected.
I’ve re-seated the GPU, RAM, and reconnected all cables. I also swapped out the DP and HDMI cords, but the problem continues. I’m unsure if the monitor is causing the conflict; I don’t recall updating my drivers since the last update was in 2017.
Any help or advice would be very much appreciated.
What cable are you using? I know some 16 pin cables are known to be flaky at the connector, you can test this but booting your PC up, take the side panel off, and just touch and maybe nudge the 16 pin on the GPU and see if the screen goes black, if so, thats your problem.
If that doesn't do anything, I've going to point at a different component, I'd start at this point to set the memory to something lower like 2400mhz without XMP, and see what the system does, if that has no effect, Run with default bios settings, still nothing I might have to point at the PSU, If you got a another one, just set it up out side of the case and plug everything in and test.
Good Luck!
I'm using 3 x 8 pin GPU cables connected to the 16 pin Nvidia connector that came with the RTX 4080. Each cable is plugged into the PSU separately, without any splitting or modifications. I'm a bit nervous about touching it because I've heard it can melt unexpectedly if not inserted properly or with enough force, and it seems to fail after being plugged in and unplugged multiple times.
This shouldn't occur on the 4080 because it doesn't use enough power to operate the plug. Most of the melting plugs are actually on the 4090, which is likely the case now. I'm not too confident about the Nvidia adapter; I've been using the one on my 3090ti without any issues, except for a messy tangle of wires. Recently I've watched plenty of videos mainly about cable mod connections, where even a slight movement can cause the screen to go black quickly.
Followed your suggestions and reconnected the 16 pin GPU adapter. No movement was noticeable with the cable, so it was fully secured. I also updated my monitor drivers, which now allows my PC to recognize the monitor as a Benq model (previously it was listed as generic). I'll keep checking to see if the problem returns. At this stage, I didn't try turning off XMP, but I'll monitor further and consider the other solutions you recommended.
A recent issue occurred, causing a loss of signal to my monitor, increased GPU speeds, no video output, and requiring two restarts within five minutes. Could adjusting the Windows Power settings, such as switching from 'ultimate performance' to 'balanced', affect my PC's performance?
For those who are curious, I believe I resolved the problem after much troubleshooting. It seems one of the GPU 8 pin power cables was disconnected from the 3 splitter connector to the GPU. It appears only two of the three GPU cables were supplying power, which likely caused the loss of video signal and increased fan speeds to maximum. After rechecking and re-clicking all the 8 pin connectors to the GPU 3 way splitter (hopefully nothing), there were no further issues, and it has been over a month since the problem started.
