Will resetting my pc to factory settings reinstall old drivers?

Basically I've been getting very poor performance out of my pc, I thought it might have been conflicting drivers from when I installed my new nvidia gpu. So i went through and deleted many of my old amd drivers, and I did get a large performance boost but still not the type of performance I think I should be getting. I'm also experiencing other weird issues and I'm worried I uninstalled drivers I may have needed, so I'm considering resetting my computer, will that install all my old amd drivers again? Is there a better way to figure out which drivers are old and which are new? And if any are missing?

Here's my specs:
GPU: GeForce GTX 960
CPU: AMD A8 7600 Radeon R7 (Cores: 4c+6g)
Memory: 8GB RAM
OS: Windows 8.1
The PC is a Lenovo x315 gaming desktop I upgraded the graphics card to GTX 960
You can find more details if you need them.

if you can think of any other possible reasons I'm getting poor performance let me know! Also I understand my cpu isn't great but I wouldn't think I'd be getting such poor performance, I'm getting major fluctuations in games like Skyrim ranging from 25-30 fps in cities to about 150-160fps outside, same with fallout NV anywhere from 30-80fps very randomly it fluctuates.

Resetting using the provided Factory disc will return everything to the condition it was when you bought it.
The exception would be if the factory had partitioned the Drive. Then everything on the D:/ partition might remain.
First: You have Defragged the Disc?
You have 50% (not less than 33%) of the hard drive clear?
All your Games and movies are Legit, no Warez/Torrent/Pirated items. If you have W/T/P items you may also have a Virus/Malware infection.
Your Graphics Card Drivers are up to date? Some Games do not like updated graphics, I once had to roll-back to the old one.
Some old game designed for the single core CPU may just need to have the "Affinity" set to core "0". As the extra cores confuse it.
