Hello! Today after restarting the laptop, I have a white screen from SupportAssist saying:

"The amount of system memory has changed. If you did not change your memory... To resolve this issue, try to reseat the memory.".

I have no idea what this means. I have not touched any RAM or memory and do not touch it or anything of the sorts as I'm a newbie at this kind of stuff. I have no clue what reseating the memory even means. Any help would be appreciated!
