Hi, next week I am going to buy a friends used Asus ROG Strix B450-F I, and I dont know if I have to reinstall the OS or flash the Bios (because I am a bit scared of flashing bios because all of the warnings it may break and stuff) + last week I already did a clean Windows install and wiped all my harddrives because of a Bluescreen issue which will be gone with the new mobo. I just wanted to ask for tips how to setup a used mobo. Thanks in advance!
