From what you have written I assume that you do not have a lot of technical experience or knowledge.
Therefore, what we need to do is try to understand what you have done and attempt to undo it. To facilitate that we need to be referring to the same things in a technical-language that both of us can understand.
Firstly, you cannot "delete" the graphics card, unless you removed it from the machine and beat it up with a hammer - which I assume you didn't do....
.... Therefore what I am understanding that you have done is that you have deleted the "Drivers" for the graphics card. With your limited technical knowledge I am having difficulty in understanding how a non-technical person would have achieved that.
If that is the case then all you need do is reinstall the Drivers. You should have those either on a CD or they should be in the Windows Drivers Folder or you can download them from the manufacturers website.
Why would you want to "Format" the PC....??? If you do that then you absolutely will not be able to do anything on that machine until you have reinstalled Windows. And with your limited technical knowledge reinstalling Windows might be quite difficult.
Perhaps the best way forward is if you tried to explain what you did in a manner that is easier to understand. Think carefully about exactly what you did and then try to relate that step-by-step. That way I will also be able to understand the sequence of events.
