Question after Rebuilding my PC

So i recently installed new parts in my rig including the following, (mobo, cpu, and gpu.) I have a SSD that i had in my rig before with Windows7 on it and a few other things on it, and a 1tb hard drive with all my games on it. Do i need to reinstall Windows7 due to the new hardware I installed or will it boot up as it reads my newly installed parts? Thank you.

It will likely boot up but you prob will have lots of drivers to install.

you might have some problems from the previous drivers running on the new hardware causing compatibility issues. I recommend you boot in safe mode, uninstall all hardware drivers for the parts you replaced, then booting up normally and get the new drivers.

I just recently did the same thing, I had some quirks that I couldn't figure out so I just re-installed windows. 

Alright, thank you for the input, i'm going to try that out, but put it into safe mode first and uninstall the old drivers.

Thanks for the input, i'm going to do that now and see what happens.

No problem and good luck! let us know how it turns out.

Yeah, that'll be my last resort to reinstall windows completely.

How did it go?
