IRQL_NOT_LESS_OR_EQUAL Blue Screen caused by ntoskrnl.exe Windows 8.1

Today, I just got the Blue Screen of Death IRQL_NOT_LESS_OR_EQUAL caused by that dreaded ntoskrnl.exe. It's only happened once, but I had to restart again because my internet connection stopped working. I then downloaded BlueScreenView and here's what I got:
