I have an old computer that is experiencing graphical related corruption as well as randomly restarting.

In an attempt to isolate the problem I want to disable the GPU so it reverts to the chipset inbuilt into the motherboard.

I have tried disabling the GPU in the device manager, but it still requires that I plug my monitor into the GPUs monitor output port, which seems to indicate to me that it isn't truly disabled.

How would I go about disabling it?

You should be able to disable it in the BIOS. They vary between companies and models so I can't give you a definite location, but it will be in the section for video.

Pull it out of the motherboard, perhaps? Can't get more disabled than that, and there's no chance of the OS interfering before it's had a chance to realise that no, it shouldn't be using it.

Check for "Primary display device" or something to that effect in the BIOS. Usualy you'll have options like On Board, PCI, PCI Express or AGP.
