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.
That WINDOWS="L" C seems funny, but I'm not sure.
About the popups, are they WareOut popups? Could try this
And looks a bit like smitfraud, in which case you download this and run the RunThis.bat while you're in Safe Mode.
And I would have had HijackThis fix

Well he said he already did that. Think it's time to switch drivers. To default Windows drivers if you're using manufacturer drivers, and vice versa. Just maybe. :confused:
