Welcome to the forum inhibitor.
These TDR errors can be caused by an array of issues, mostly hardware related. It requires detective work to find the cause.
The nVidia 200 series graphics cards were prone to these issues. While nVidia makes the graphics engine it is the manufacturer (EVGA, PNY, etc) that makes the card. A lot of cards were replaced in what amounted to a silent recall. So don't rule that out.
Because your problem persists whether the on-board or add-in graphics is enabled I think you may be looking at other causes, like RAM, Power Supply, or overheating.
I helped a guy in this forum a while back who ultimately solved his TDR problem by replacing the RAM. Thing is, his old RAM passed Memtest without errors. So while running these tests is an important diagnostic, it is not an end-all.
Take a look at this thread (post #9) and see if you can self diagnose the cause of your issue: Random freezing/crashing with Nvidia GeForce GT 220
