Reinicio automatico de zorin os [Translation: Automatic restart of Zorin OS]

instalé zorin os 18 en mi pc, pero tiene el problema que se reinicia solo, dañando mi trabajo no guardado, en ocasiones se reinicia dos o tres veces seguidas, qué puedo hacer ?

When the reboot happens, please check the log app in Zorin 18. It could be many things from overheating to hardware malfunction. So check the log and if you find anything, please post it here that might be related.
