My Dell Inspiron 15" has started to reboot on the middle of operations. With no prompt or hitting any keys it will just go black and restart.
Sometimes this occurs after 5 or 10 minute of operations or sometimes after an hour or two. Has anyone had this problem.
Have you checked whether the laptop is overheating? It might have some issues with any driver so I recommend that you make an update to all of the drivers on your system.
Are you working on battery or on power cable? If you work with the battery in, try to plug only the charger to the jack and work with it. Does it give you any error?
