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.
the drivers should be in your add/remove programs.. might show up as nvidia.. click it then remove and it should give you an option on what to remove..
If all else fails, go to each entry in Device Manager that is related to the chipset, right click > Uninstall > tick "Delete the driver software for this device." > OK.
You can also go to guru3d.com and download their Driver Sweeper program. Keep in mind unless you uninstall before you clean you likely blue screen. I would suggest only running it after you get the new board installed, just to make sure you've cleared out all old software.
