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.
MSI used to be company just like any other ones, but their custom Twin Frozr thermal design really sets them apart nowadays.
I know I'll be looking out for an MSI card in my next purchse ;)
Those voltage variations with the PSU look well within the acceptable limits. Even so, I wouldn't trust software readings of PSU voltage
nv4displ.dll sounds more like a video driver problem. Did you try reinstalling/updating to the latest video drivers?
