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
BFG ATX-1000W PSU
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.
