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.
VPU recovery pop up suggests that the card is overheating and crashing. You should look into that first, try running games or something 3D with the case open and see if it still crashes. So based on this information, it seems your friend is having a hardware and not a software problem.
ps. There was problems with VPU recovery not working right in the past, but if you have more reacent drivers, say 6.5+ it should not be an issue.
