Strange Blue Artifacts

[FunsOver]

Hi guys,

This is pretty long winded so try to bare with me.

The Problem:

For the past few weeks sometimes when I boot my computer and log into windows there is a strange blue artifacting, almost like sand. Restarting the computer or even changing my resolution seemed to fix it, however lately it's happening a lot more often, multiple times a day. It mainly affects windows rather than applications and I can almost force it to happen by loading a game then alt tabbing enough times for it to happen. The same is true for getting rid of the artifacts, if I alt tab enough they go away. I think there may be a problem with the resolution as a guess? I have a 4k TV as a monitor but I run everything in 1920x1080 and use 150% scaling in Windows. Here is a video of the problem:

Just a side note - is the GPU usage dropping down to 0% an issue?

What I have tried:

I've gone through most troubleshooting steps I could think of:

• Updating Windows from 1809 > 1903, still persists, if anything it happens more often
• Updating video card drivers from 19.3 > 19.5 > 19.6, each time using DDU in safemode and not connected to the internet. However once the drivers finish installing the final confirmation screen has a green overlay which disappears upon restart
• Ran SFC /Scannow, no issues found
• Updated NetFramework and Visual
• Safe mode, I am unable to recreate the problem in Safe mode by changing the resolution, however I am yet to try a game in it
• Benchmarks/Games - I can play most games on max with no issues, but once I alt tab the issues start. I have ran Heaven, 3DMark, Kombustor, I am unable to find any artifacts in there
• GPUMemTest - Result are fine
• Different Cable/Ports I have tried a different HDMI cable in different slots on both the card and the TV, problem remains.
• Reseating

What I have not tried:

• Different Monitor/System, I only have and have access to one monitor and one computer, I'm unable to test with anything else
• Reinstalling Windows, I'd rather see what you guys think before I try this.

Specs:

• Gigabyte H110M S2H
• i5 6500
• RX580 8GB
• 2x8GB DDR4
• 2TB HDD
• 128GB SSD
• EVGA 600w White
• Windows 10 Pro 64bit
• Toshiba 55T6863DB

The system is around three years old except for the GPU which is two years old, I have never overclocked. I'm really not an expert and I hope this isn't the case but this points to a faulty GPU in my opinion. The fact that the artifacts are waiting for me once I log into Windows when there is no stress or high temperatures, however it seems to function fine until I install the drivers and the fact that I can play games for hours, for example Hitman 2 on almost max in DX12 with no issues but as soon as I alt tab it begins in Windows is a complete mystery. I hope you guys can give me some insight and help me fix this issue.


Thanks,
FunsOver.

Hi,

Thanks for the quick response. Is that certain? Is there anything I could do to rule it out.

If you have a TV could you plug the PC into that? Could you take a screenshot and post it on here?

Hi ltron,

I am actually using my TV as a monitor, I could ask a friend if they have a smaller one I could use to test if you think the TV could be at fault?


UPDATE:

Managed to get a 2nd TV to test on, the results can be seen here:

The short of it is:

• Artifacts on main TV
• Plug into a different TV
  
• Artifacts gone
• Plug back into main TV
  
• Artifacts are now gone?
