Overkill is no problem, I like overkill. If you can borrow another Graphics card, let's try that first and make sure it is not your GPU. Uninstall your old drivers first. If you are getting another Nvidia card, uninstall the old drivers by this tutorial and shut down instead of restart. Just be sure the Graphics driver is the last one you uninstall. Swap the cards and do the installation part of the tutorial with the new card in.
NVIDIA Drivers - Avoid Problems
If you are getting an AMD card, uninstall your current drivers as in the first part of the above tutorial, then shut down, swap cards and custom install the new drivers. All you will need is the Graphics Drivers. If you have problems, run DDU and select only Nvidia Display drivers.
