Pretty much this.
The event viewer is filled with errors, even for a brand new install. They aren't always generated close together either. The error i was asking after gets logged a little while after booting - hence the clarity (as i have no way of knowing what you looked for; the two listed are almost always visible on the same section and for people, that's usually enough).
But as i say, a system dropping is a sign of a hardware issue of some sort; it's unlikely its a terminal issue [the hardware itself] as a terminal issue would affect more processes. More likely the drivers - These can be for your keyboard, mouse, sound etc,.
If you have a spare GPU laying around, try swapping it in and seeing if the issue goes away.
EDIT:
If swapping the GPU still does nothing, then start with the other things you plug-in, failing that try (if you even remember which) removing programs that asked for admin privileges (either to run, or when installing [e.g. Afterburner]).
