No problem, glad I can help
kernel-power error means that something is not getting enough juice and the kernel sends a SIGTERM and halts the system.
So now, we need to figure out what is doing that; while highly likely to be the graphics card, but not with 100% certainty at this point.
For instance, if your GPU takes a good bit of juice away and something else needs that power, then the GPU is causing the issue, but only because its using the most power in a system that may need more.
So, if you could give us a complete list of the components in your rig, as well as any over clock settings, that will help.
