Hello and welcome to my problem
I have successfully used a bootable USB to nuke my laptop using DBAN, and have now reinstalled Windows 10 (had a pesky virus, and this seemed the only option that would finally free me)
The virus has - due to recklessness - transfered it's way to my stationary PC. So my question is, due to the fact that my pc is not made complete in a factory, and therefore each part was manually put in and installed, is it then neccessary for me to backup all of the drivers and the like for various things (CPU, GPU etc.) - and if so, what is the easiest way to do this?
I haven't build the computer myself, and I only managed to DBAN my laptop after several hours of Googling.

%SystemDrive%\Windows\System32\DriverStorefolder. This will allow you to easily install any device drivers (within Device Manager) that may be missing after an OS clean install. – Run5k Apr 11 '17 at 20:14The thing is, the machine is one-of-a-kind, meaning that I can't really do a backup of the driverstore folder where it isn't infected

Since the release of Vista, theDriverStorerepository has made this much easier with this native OS capability readily available. – Run5k Apr 12 '17 at 00:24On Holdyesterday, so a more "modern" answer can't be added. The other question flagged as a possible duplicate is probably closer to what the OP is trying to do. Regardless, I do appreciate your feedback! – Run5k Apr 12 '17 at 12:46DriverStorerepository, it seems as though it was canonical for a much different environment. – Run5k Apr 12 '17 at 13:13
