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.
Usually a overclocking issue/ heat issue. Or the card gave up completely, but then you prolly wouldn't post here right now unless you're at your second computer.
might not just be the card. Your proc is heavily overclocked as well, maybe your memory. All these things could be the culprit. It might not be the card at all.
