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 can guess on some 'basic' reasons:
Power Outage / System Crash - Enter incomplete and or corrupt values in memory addresses such that the card can't figure out what to do anymore.
Using a Different Card / Maker BIOS - Different order of memory addresses and or different sizes of memory...
