Yesterday, Steam worked perfectly fine. I shut down my computer, which installed the Microsoft .NET Framework 3.0 Servicepack, and now Steam doesn't work. Whenever I try to log in, I'm told it can't connect to Steam servers. I tried everything on their troubleshooting page for the issue, used System Restore to go back to before I had installed the Windows update, and I reinstalled Steam. I became unable to access anything Steam-related (most of their website, client) besides their support section of the website after I used system restore. My brother's computer doesn't have the .NET Framework 3.0 Servicepack and his Steam works fine. I'm starting to think that my dad is just being an internet douchebag Nazi as usual and he found the port that Steam uses and blocked it for my IP, but I doubt it, since he prefers just disconnecting my internet completely. Who knows what the problem is?

This new computer is kind of seeming like more and more of a huge crock of shit.
