How to use my old HDD on a new mobo/cpu?

[dagamortal]

First of all I'm running on a dell 560 motherboard,cpu and HDD, and I got a new processor on an AMD FX-8350 with an Asus M5A97 motherboard.(they will be delivered in a week)
Currently I'm running windows 7 Home Premium and got a Windows 8 pro, and i plan to format. Got a few questions but now it's should I format when the new parts are ready to use, or should I format earlier and just wait for new parts to get here? Also, if you could tell me or show me an easy guide to start up a new computer.
Thanks for the help

Put in your new parts and re-hook up your HDD then.. start your PC up with the new OS in it and run through the processes. It will delete all your DATA though so backup on a external drive if you have one

Ok, so my data is backed up. So i basically connect everything and put the new OS disc in it too Then run through everything ?
Thanks for the answer btw

yep pretty simple right? haha, its just as simple as connecting them and running through the new software OS
MAKE SURE your external drive is disconnected. have a good one
