Usually indicative of inability of the psu to supply the power needed by both cpu (not kernel errors) and/or gpu.

I would try another PCI-E power connector instead of the one that is plugged into the graphics card. Also make sure it is connected security and not slightly loose. Check if the card is seated correctly.
