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.
You should be fine. I was able to upgrade from a P35 chipset to P67 without a reformat, thanks to Windows 7 coming with generic Intel SATA drivers. All I had to do was install the drivers that came with the board and reactivate Windows.
nope shouldn't have any issues, only time windows really freaks out is when switching between an Intel and AMD and Intel/AMD and a nvidia motherboard. though 9 times out of 10 you can usually just delete the chipset drivers then shut the computer down, make your changes and boot back into windows after.
