Generic Windows 7 can cause issues just like generic drivers from AMD. Also, when you reinstalled Windows, did you use Windows 7 from the Toshiba Disk Creator or a generic Windows DVD/ISO? Same thing here could happen. Not saying this IS what happened, but it is a possibility. It's even possible that the overheating could have damaged some components. Your system starts to overheat and Windows starts giving errors. Now you install a new driver direct from AMD and those power limitations are gone. So Toshiba tweaks the driver to limit the power draw down to 22 watts and the graphics chip never heats up to more than 85 degrees. Now lets say that Toshiba wants to install that graphics chip into one of their laptops, but 97 degrees it too much heat for the cooling system to handle. Let's say it has a TDP of 26 watts and on full draw, heats up to 97 degrees. The AMD 560m mobile graphics chip (don't know if that's even a thing). As an example (and just throwing out numbers. Laptop manufacturers will take those drivers and tweak them to limit the power draw and heat ceilings to conform with the specifications of the laptops they install the chips in. These drivers are, for lack of a better term, Generic drivers for any particular graphics card. Graphic card drivers are created by the chip manufacturers (AMD/NVidia/Intel). It crashes because you downloaded and installed a driver direct from AMD.
