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.
Well, since you don't know what's causing it, I'd say General Hardware. But it might help if you could give more details than just that it's making a rackety noise.
There are only a couple of components that actually move, like HDD, heatsink fan, power supply and case fans. Once you narrow it down to the component, you can switch your search to the specific forum for better help on your problem.
