Random Black/White Lines Across Screens After Continuous Use

Over the past few weeks I've noticed something curious about my system. After the system has been on for a while, usually two or three days, I star getting random black and white horizontal lines across my screen. The artifacts stay on a page until the image is refreshed (i.e. if I scroll down the webpage, if I refresh the desktop, if I open another program, etc.). The issue starts off very minimal, only occurring every few minutes. However, over time (with or without putting the computer to sleep or leaving it to idle while I am away) it progressively gets worse. If I reboot the system, it stops doing it for several more days, but then starts doing it again and progressively gets worse. I have ran the following test to see if I found any errors or could stress the system to cause further issues or increase the occurrence/severity of the issue to no avail:

memtest86+ NO ERRORS
prime95 (all iterations) NO ERRORS Max Temp CPU: 46C
furmark (max settings) NO ERRORS Max Temp GPU: 76C
sfc /scannow NO ERRORS
Malwarebytes NO Detected Objects
Defender NO Detected Objects
PSU Test (Dell Tester) All voltages in normal parameters.
Note: HWMonitor and Speccy show +12V as 15.400V while SpeedFan shows it at 10.12V. Not sure if this may be an indication of an error, or just shows the inaccuracy of such monitoring programs.

Below is a list of my system specifications:

MSI 870a Fuzion Power Edition
AMD Phenom II x6 1100T
Corsair H100 Closed-Loop Liquid Cooling System
Gigabyte Windforce 3x Edition NVIDIA GTX 770 4GB GDDR5
MSI Hawk Edition AMD Radeon HD 6870 1GB GDDR5
Samsung 840 EVO 256GB SSD
Western Digital Black 1TB
Western Digital Blue 1TB
23’ 1080p 60Hz Monitors.
NOTE: Connected via DVI-D. Two of them run off the HD6870 while one runs off the GTX770. The issue occurs on all three monitors.

Windows 8.1 64-bit with all current updates.
All drivers are up to date.

I have never noticed the problem in Windows 8 Metro Apps or inside the Start Menu. This leads me to believe that it may be software related. However, I have done a complete system reinstall but the issue persists. Any assistance or recommendations is greatly appreciated.

  1. does it matter what is on the screen?

    Does the desktop have the lines as well as , say , a web browser?

    Yes. It appears on the desktop background as well as in the web browser. I notice that it seems to start off in Chrome and the Desktop, then migrates into other applications like skype and spotify, then eventually it starts to happen in the Windows 8 Start Menu and Windows 8 Metro Apps. Though, it is very very minor in Windows 8 menus and metro apps. Even once it fully progresses to the the point where I have about ten to twenty lines across the desktop/chrome, the metro app will only have one or two may every couple of minutes. 7
  3. why do you have two graphics cards?
  4. I use one for my main monitor that runs all graphic intensive programs. The other is used for secondary monitors that run things like chrome, skype, etc.
  5. So you have different graphics drivers operating in different profiles?
  6. Best answer
    The first change I would make would be to ditch the second card , and its associated profile

    Connect the secondary monitors to the primary card
    Windows 8 has excellent features for multiple monitor set ups
  7. I will try it and see if that fixes it. I will update accordingly. One other thing, I have an issue where my system randomly decides to "black out," the computer stays on and motherboard shows power, and everything is on. You believe it could also be the cause of that?
  8. I believe thats a graphics driver fault as well .
    I suspect these issues are related
  9. Alright thanks for your help! I just removed it; we will know for sure in a couple of days.
  10. It started doing it again. I know AMD drivers are bad about not fully uninstalling. I am going to try doing a fresh install of my system and see if that corrects the problem.
  11. Do you think that MSI Afterburner could be causing these issues? I only use it for GPU monitoring on a Logitech G510s. I finished a complete re-install of my system; I am waiting on installing MSI Afterburner until I hear back from you.
  12. Well it started doing it again.......
  13. So I did some testing.. and found that it was my DVI to HDMI cable connection on one monitor that was causing the issue I believe. Whenever it starts to happen if I unseat that connection and reseat it, it stops doing it for a while... Is that even possible?... for it to affect the other displays?????
