Will I lose my graphics/motherboard drivers if I restore windows 10

I custom built a PC and installed windows 7. I recently upgraded to 10 after upgrading my windows 8.1 laptop. I never reset or reinstalled windows on my PC when I was running windows 7 simply because of how tedious a task it was but now that I have 10 it can be done easily and so I wish to. The only worry I have is that because my PC was custom built I worry the drivers for my graphics card, motherboard, disk drive etc that I installed from the CDs they came with may be lost in the reset as the drivers may not be "baked into windows" like drivers for pre-built PCs. The only reason this is such a concern is that I no longer have the disks and cannot find the drivers online or locate all of the files within my PC. Can someone please either put my mind to rest and tell me I don't need to worry or offer a solution if it will remove them. Many thanks, Matthew.

I have a sapphire radeon hd 7770 vapour x and a gigabyte (i forget the exact model) motherboard

MS has provided a pretty robust driver suite for the Win10 OS IMO including the most current AMD video drivers. I did not have to go to outside sources for drivers except the chipset driver for this version of windows.
