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.
I would advise to make sure you have the latest mobo bios. And possibly reseting of the settings in said bios and undoing any overclocks temporarily. I had similar issues with same brand but different board but same generation this worked for me and I was able to reinstate my CPU overclock later...
Obvious answer, have you tried a different USB port? I had a similar problem with a different device from which this solution worked. Later had reinstalled windows and original port began working again aswell, weird tho.
