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 just had a similar event with a 7900x and Asrock B650M Pro RS WiFi. PC is on a UPS and never showed any signs of issues. All I did was a reboot and it will not post anything, all I get is the CPU and RAM error MB lights. My CPU is out of warranty but the MB is not. I'll wager the CPU is dead.
