Hello everyone. I've got a problem on my laptop. I was playing GTA V and talking with my friend over Skype. And the My computer decided not to connect to internet. So I tried to restart. To restart it took really long time, so I decided to press the power button to force reboot.When the laptop started, it said the it detected hardware changes, and it told me to restart. But I know that I didn't even open the laptop's bottom cover and change anything. Sometimes the sound disappears, but it can be fixed by shutting down or restarting. Also when the message is shown the screen starts flashing. Please help.
