Freebook 360 memory problem

I have a problem with my computer which has been used very little because I only use it for outdoor events to run my machine tools and do my accounting. I only used it for 4 or 5 events in 1 year and a half or ten days at most, and at present I am unable to do updates it does not download, in addition the PC spits out with a memory access message, I suspect the SSD but I bought an NVME but even with windows installed on it the pc does not want to boot on the nvme, I end up with an error message

Moreover, the after-sales service does not respond to my requests :frowning:

Could you be a little more explicit, in order to help you I would need to at least know what error messages you are getting or for you to post images of the errors.
