You need a very old GPU if you want one that is not sufficient for Windows 10, if there are problems with the GPU we would be talking about a faulty one, not one that is insufficient.
If it is the best way I do not know, at least your board need replacement as the BIOS is way too old + there is no Windows 10 support, or you need to revert back to an older OS (which is your choice).The best way is another board, memory and graphic card ?
Your GPU I don't know the situation of, that's what we're finding out after you replace it or use it in another system.
The memory test indicates it is fine what is pretty reliable.
