Hi. I have one problem with my laptop. Periodically I have see blue screen and after restart - no operation system - message. After second restart laptop work well some time. And again blue screen. If I have big work with data on disk, the problem will be more fast

Hi @cartune77

There could be a few possibilities as to why you are experiencing this.

Its possible the hard drive is failing but it may be something else.

Do you have anything plugged into a usb port when you are booting and getting the

no operating system message?
