I was able to do a system restore and it removed all updates I did through Vaio Care. The laptop fan still runs very high, but I am able to access WiFi now, which helps due to the laptop not having a Ethernet port. Yes, it would blue screen, or it would fail to install all together. The last couple times it has blue screened, it freezes on the screen. There is no sign of it doing anything else as the percentage doesn't change
