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.
This sounds to me like a power problem. Try plugging directly into the wall and see if that helps. Do you have any lights on dimmers in the house? Sometimes they will cause noisy power.
You might even try bringing the monitor to a friend's house and see if it does the same thing.
