I recently started working out from home due to this covid mess and accidentally laid down my weights on the desk a bit hard. Almost immediately my screen lit up with checkerboard pattern artifacts and since then after some time using my PC whenever I knock my elbow on the table even lightly, such as to rest it the artifacting appears in differing patterns and sometimes restarts the computer completely. My PC specs are Intel i9 10900KA CPU, NVIDIA RTX2080ti GPU, ASUS TUF Z490 Gaming Motherboard with Wifi. I would've thought the GPU would be able to withstand more force than this, and I know its not an issue with monitor or HDMI as I've tried different setups. PC is Prebuilt by Centrecom Australia.
