Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Is it safe to delete (and then re-create) a primary partition while re-installing windows or should we refrain from deleting the primary partition and instead do it's formatting?
When I do a fresh install, the first thing I do is fdisk the bugger and nuke everything there. You don't even need to recreate the partition (you can if you want), the windows installer will prompt you to create one if one isn't detected.
