After completing the "Ill met by moonlight" quest I used the tcl (Clipping Off) console command, to remove collisions, so I could run in a direct line to my next location.
However within a matter of 30 seconds my screen when a light-ish blue colour with some odd pixelating effect and the sound began to stutter on the same note over and over again. After 3 or 4 seconds it completely rebooted my computer.
The second time it occured the "tcl" command was off (so i was back to normal game rules), yet it still did it.
I have tested my RAM and SDD/HDD's, none show any issues that cause concern, my computer is more than capable of playing skyrim without any issues. (My OS is Windows 8 Pro)
If it helps, I have NO mods installed, 51 screenshots and I've completed the main quest line.
Other than that I have no idea what can be causing this.
Any help you might be able to give would be wonderful and I would be thankful to any and all who can help contribute to solving this pesky issue.
