Help my pc restarts by itself

Hello, i;'m using dell latitiude 7390 user. and dualbooted the zorin os with windows and i have a problem. Sometimes it just restarts and i have to log in again and lose eveything i opened up. or sometimes the pc is very slow and then it restarts by it self. so can any one suggest me a way or command to find this out? thanks for the advice.

In most cases, these sudden restarts are linked to one of three common issues: GPU driver instability, faulty RAM, or thermal throttling/overheating.
