Hello, I have questions that might sound silly to you guys. I currently have i5 3570k with Asrock z75 extreme 4 and I ordered i7 4790k with Gigabyte z97 gaming 5. Other parts will remain the same including my hard disk (HDD and SSD). I plan on reinstalling the OS but do I have to do anything to the previous OS? or when I'm installing a new OS, will the old one be erased automatically? If not, how would I delete the old OS from my SSD if it is taking up some space? O and I would like to keep my data, so formatting would not work and I have no other hard disk to back up my files. If back up is required, will backing up on the HDD be fine and after the installation is done, delete them?
Thank you
Thank you
