GPD Pocket4 H370 64GB Screen artifacts and lock up

Hello,

I have been using my GPD Pocket 4 fairly often and take good care of it. Last week I went to turn it on and the screen would not come on. after a few power cycles I managed to boot into windows but as soon as i started taxing it , the screen would start showing gibberish. Any type of video game will also trigger this and it will lock up. I have even seen it lock up while in the BIOS.

I have updated everything to the latest drivers. The issue is even more prominent when plugged in. I have checked thermals and nothing seems excessive.

Any idea what may cause this?
