Random BSOD

[proffsetpatrik]

Please excuse my bad English. I hope you understand the most.

 

I was browsing the web when everything seemed to freeze, the taskbar had frozen, the start button had frozen etc, a messaged that said something similar to "Microsoft Windows has stopped responding" popped up. After able of doing nothing to make it work again I rebooted the computer. It worked fine for what I believe was 30-60 minutes until the same thing happened again.

As before I rebooted the computer, and this time I got a message saying "Reboot and select proper boot device or insert boot media in selected boot device and press a key"

 

 

I rebooted the computer and selected the boot device. Soon I launched Windows into safe mode, and scanned w/ malwarebytes for some reason. However IT FROZE AGAIN and I had to reboot the computer. This time I launched it into normal mode and is currently typing this.

 

I'd like to know what caused this, and how I can prevent it in the future.
