Auto reboot after 5mins of playing of secrets of solstice

This sounds like an overheating problem. Newer games are graphic intensive and the cards required to run them generate alot of heat. You will want to make sure your laptops's vents are free of dust and then check the fan. To get the best performance you may want to upgrade the fan. If your fan is working properly and the vents are free make sure you are playing with the laptop on a surface that does not obstruct the vents. You could also purchase a product like a laptop cooler which basically is a cooling pad that you sit the laptop on while in use. Good luck & I hope this helps.
