I don't know if this is the right place to post this but I've been having issues with my Arc 750 gpu I acquired last year, new. When I have some games open i get pretty bad artifacting or visual glitches that vary in size, shape, location and color. Attached are two examples. There are two other types of graphical errors that are harder to replicate, which I have yet to photograph. They are a large black bar near the top of the screen that stretches from the left end to the right end, taking up approximately 1/6th the screen, and little grey squares spread across the screen, somewhat far apart from each other. I've tried two different displayport cables, one hdmi, two monitors and it still happens. I tried running memtestVulkan and memtestCL and no errors were detected within two hour runs of each.

Hello,
Thank you for posting in our Community.
I looked at the pictures of the issue and this would normally indicate a hardware problem, perhaps the GPU itself (cables and 2 different displays already tested).
There are other potential causes so let's get to it first.
- Please update the graphics driver to latest version 32.0.101.5971.
- Make sure the power supply is at least 600Watts and use both the 1x6 and 1x8 power connectors to the GPU.
- Avoid using adapters, converters or KVM switches while testing this issue to eliminate these as possible culprits.
- Are these visual anomalies occurring only on specific games or apps? If yes, which ones?
I would like to familiarize myself with your system configuration so I can try to figure out what else might cause this. Attach the Intel SSU report so I can take a look at it.
Best Regards,
Ronald M.

Took a while to recover my account.
- Please update the graphics driver to latest version 32.0.101.5971.
I did and they still show up - Make sure the power supply is at least 600Watts and use both the 1x6 and 1x8 power connectors to the GPU.
Using a 750Watt psu with the two cables like you said. - Avoid using adapters, converters or KVM switches while testing this issue to eliminate these as possible culprits.
Using either direct hdmi and displayport connections and they still appear. - Are these visual anomalies occurring only on specific games or apps? If yes, which ones?
at first it only showed up in high resolution games but now it appears on the main desktop and while using chrome.
