3 monitors breaks GPU drivers

[Nathan5660]

So had some scary issues with my brand new RTX 3070 today. I shutdown lastnight when I went to bed, and when I turned thed pc on this morning Everything on screen was flickering, the mouse wasnt working properly. It was almost the same as having the wrong drivers installed, except they were correct. 

 

During my troubleshooting process I unplugged all but on of my three monitors, INSTANTLY fixed the issue. Plugged the second back in and shut down, the turned the pc back on. Everythings fine, which points to the third monitor being the issue. 

Could it be the HDMI to VGA adapter I use with it? I literally just use it as a glorified clock TBH with Windows 10 wigets from the Microsoft store, so its not THAT important in the grand scheme of things. 

 

Could that be what the issue was? The issues only started when GPU drivers were installed on the System. Without drivers it was fine, the femto second I installed them is where the issues began. 

 

Im not going to plug the other monitor back in, cos I know its going to break everything again. Why would a display adapter cause these issues though? Never had any issues with it before at all. Is it something to do with new GPUs or something perhaps?

I had it happen on my 4870 or 970 (Don't remember) good few years ago and I was using a DVI to HDMI adapter for my primary monitor, weirdly enough the problem went away on its own, I did change out the drivers, but just throwing this out there if it helps debugging on your end.

I've only had a similar issue when trying to apply DOCP settings on RAM which was fixed by reverting settings/updating motherboard firmware once they released a new version.

 

Maybe check to see if your motherboard has a firmware update with stability fixes.

I just remembered, the 3rd display was a vga one (TV, annoying scaling issues using HDMI, didn't have the settings to turn it off) , used a dvi to vga adapter for that one (The dvi with the analog signals still present)
