Baking is not a fix, baking just heats the chip up inside and futzes with the internals a little bit. The chip is still dead, and it is bad and will fail again. Baking is not a fix.
Replace it with a new one.
If we are talking about the AMD GPU problem from 2011, yes, that CPU has integrated graphics. The blanket fix is NOT about making the system use the integrated graphics, it is about heating it to 125c long enough for the chip to &&^& itself up inside that it works again.
If we are talking about the NVIDIA GPU problem from 2007-2008, there is no integrated graphics there whatsoever that you can switch to.
