Hello,

 

I have a thin black line running horizontally across the top of my screen. It has been persistent for weeks now. If it were a few mm higher it would not even be noticeable. I have exhausted every option I can think of so far. Here is how it came to be:

 

I decided to dust out my pc with compressed air, I then played some overwatch and decided to OC my video card and CPU because my GPU temperatures were lowered from the cleaning.

I overclocked my 290 to 1100/1260 with MSI afterburner and my i5 3570k to 4.0 GHZ through the asrock z77 extreme 4 BIOS using these settings I found online:

 

Offset mode

 

All Core=40

 

Additional Turbo Voltage: +0.004v

 

Offset Voltage: +0.005v

 

Enhanced Halt State (C1E): Enabled

 

CPU C3 State Support: Disabled

 

CPU C6 State Support: Disabled

 

Package C State Support: Disabled

 

Both seem to be mild OCs and after stress testing the temperatures never went about 80c for either CPU or GPU.

I downloaded Titanfall 2 to try, played it for about 20 minutes, then went back to overwatch and noticed the black horizontal line on my first game. The line is persistent on the desktop, browser and even the BIOS.

 

To attempt to fix this issue I immediately reverted my CPU and GPU to stock settings. Nothing.

Uninstalled titanfall 2, upgraded my graphics drivers, reseated my video card, changed resolutions, used the secondary DVI slot on my video card, killed all power to PC and monitor and hitting the power buttons to discharge them, still nothing.

 

I have reinstalled Windows 10 on a spare drive, updated my BIOS to the latest version, tried various different drivers for my video card, removed the video card and ran through onboard video only and even tried a different monitor with a different DVI cable and the problem is STILL there. I have no idea what else to try.

 

It is NOT the video card.

 

It is NOT the monitor.

 

It is NOT the RAM.

 

If it is hardware related I believe it must be either the motherboard, CPU or PSU because those are the only things I have not tried a replacement of.

 

The line is very thin on the left side, and becomes a few mm thicker near the right side of the screen.

 

I'm looking for suggestions on what else I could try to potentially fix this issue. I am currently unable to obtain a new motherboard/CPU/PSU, especially without knowing which might be causing the issue. They could all be fine and it could be something else entirely, I just do not know what else to try.

 

Any help in resolving this issue would be greatly appreciated! Sorry if posted to the wrong forum. I wasn't sure which would be best suited since I don't know what is causing this.

I bought a brand new monitor thinking it was an issue with my old monitor, so this is the backup screen

ok then its not software, has to be a hardware problem and it can't be the monitor seeing as you have two and the problem remains,and you tried both onbord video and main video card and the problem is still their.

You try changing monior cables ?

Yes. 2x DVI and 2x HDMI. It must be the motherboard, or possibly the CPU/PSU. I'll live with it for now until I can afford a replacement or if it gets worse I'll just upgrade. Thanks anyway though
