Hello,

Quite recently I've been experiencing a problem with my monitor. There are weird grey-ish horizontal lines on my monitor. They range in size. Sometimes they're so small you don't even notice, and other times they're larger, flatter lines. I checked my GPU and it's seated fine, I did unseat and reseat it though, just to be sure. I reseated my RAM, and cleared out any dust. I have an ADVUEU monitor, it's kind of old, to be honest. I really can't afford another one. Anyway. This issue started up about 2 weeks ago but would fade away for hours on end so It didn't bother me so much but now it's a real hassle. I changed VGA cords, I have a VGA to HDMI adapter, my monitor doesn't have HDMI. 
I also plugged in my VGA to my TV and the lines were still there, so I don't think it's a monitor issue. 

I want to think that my VGA to HDMI adapter is the issue, but I'm not sure at all.

 

My current set up is CyberpowerPC Gamer Ultra NVIDIA GeForce GTX 950 w/ AMD FX-4300 3.8GHz

You're right - if you get the same lines when using your TV as a display then the problem is not with your monitor.

 

Your VGA to HDMI adaptor is presumably not connected at all when you're using your monitor as you say your monitor does not have an HDMI connection. If this is so then the adaptor is cannot be the problem. If you do have the adaptor connected somehow while using the monitor then disconnect it & see if the problem goes away - if the problem remains then again the adaptor cannot be the problem.

 

You have changed the VGA cable - so presumably this is not the problem - but changing it again for a cable you have proven OK on a different system would totally confirm that.

 

Which leaves the graphics card - which your post suggests you have looked at but not removed. If this is correct then remove it, check heatsinks / fans / connections are reasonably clean & then replace card. Make sure the Graphics card cooling is working OK. If the problem still persists then the next step is to try an alternative graphics card (or onboard graphics if your system has this). It doesn't need to be a high performance card for test purposes - just enough to see whether you get a display without the lines. If the card you try has a different chipset than your current one then you will have to uninstall your current video drivers & install the ones for the trial card. If onboard graphics removes the problem then you will still need to try an alternative graphics card to finally confirm that the problem is not with the motherboard.

 

I think that you will end up finding that the graphics card is the problem as it seems unlikely to be a motherboard fault.
