I'm using a PC with gigabyte motherboard and intel dual-core processor
I am getting static lines on my display, my graphics card is geforce 9500gt
I thought its a cable problem so I changed 3 cables and nothing changed.
Then I thought its a screen problem so I changed screens and still problem persists.
I assumed then its a faulty graphics card, so I connected the screen through the built in graphics processor in the motherboard, and problem still exists..
There are no messed up capacitors or anything in the graphics card and the motherboard superficially looks ok.
What could be the problem? I am assuming its a grounding problem or something,
Any help would be appreciated

Never. Always keep the Amp in particular well away from monitor. Can cause screen havoc if the monitor is not shielded good for MI.

Anyway. I will presume that that both the GT card and the on board work in windows if you disconnect one and connect it to the other.

So I would advise that if you can disable the on board solution via the bios if you can.
And make sure the first primary init display device is Pci-e.
Then if you can uninstall the intel graphics driver to do with the on board.

It may solve the problem as the clash might be with two video outputs using two different graphics chip sets. Co existing, and running at the same time within windows. It`s what I would try next. I mean you only ever use one primary source for...

Good trouble shooting there! You ruled out cables, video cards, and and monitors/screens. The only thing that I see left is a software problem.

I don't think grounding problem. With analog equipment I would jump on it but not with digital. Perhaps it could be but ... Since you switched monitors and the graphic card and cables it isn't a sync problem. The only thing that I can think of is drivers.
What video cards were you using? Similar brand such as AMD/ATI for both cards? Using the same drivers perhaps.
I'm following this one as it is a good one. :(

I don't think its a software problem because when I connected the cable to the video card and when I connected it to the motherboards vga, the problem still existed :/ But I will try redownloading the geforce 9 series driver and tell you how it goes
I'm using geforce 9500 gt video card btw

Its because of the refresh rate set for the resolution is wrong or slightly too high for the monitor to handle.

If they are white lines that flicker randomly, when playing a game or when you scroll in a webpage, or sat on the desktop.

The monitor cannot cope with the current set hz range set.
There are options to set to 60hz, or 59hz on the resolution in windows display.
Or select a lower Hz range with the resolution wished. Resolutions can have a multiple Hz range So a flicker or artifacts means the screen cannot cope with the updates in hz set on the graphics card and need to be lowered. Or the monitor cannot handle a resolution at at set Hz range. Resolution needs to be lowered.

The other cause, any amp or speaker setup close to the actual screen.
Electro magnetic interference. move the amp away from t.he screen

Its one or the other.

And there you go.

Shaun, I thought the same thing but he changed monitors and I figured both of them couldn't be having problems with the card mis-reading the information from the monitor. GOOD one on the interference. Most of us don't know or have long forgotten magnetic interference. That use to be the number one answer in the old days.

Do you have any old speakers sitting next to your PC or display? :)

The refresh rate is the minimum which is 60 HZ and I can't choose anything lower than that, I tried too high like 72 and problem still persists

As Shaun mentioned. the refresh rate may be incorrect. On the monitor see if there is a self adjust button and try it. Probably won't help but..

Try looking at your display's refresh rate. Downloading the drivers may fix it if it resets previous settings.

I'm all out of guesses. :(

I mean you only ever use one primary source for video output The Gt or on board so it may be conflicting.

Give it a try see if it resolves the problem, and let us know if it fixed the issue.
