Clean Up Computer

My computer is totally wacked. I turn it on and it says that there’s something wrong with the BIOS (I have no idea what that is) and to hit F2 to contine and I do but then something goes wrong and I get a blue screen so I restart my computer with the power button and it brings up the screen about the BIOS when it restarts but as its trying to do the next thing I hit F8 and then I choose to start windows normally and then my computer goes on. Once my computer is on its restarts randomly and is soslow. Also online, I can’t go to hardly any websites without this "Certificate error" thing. As far as virus protection I had Windows firewall and AVG (the free one) and this other lavasoft spyware thing. Well I ordered virus protection from Verizon but it wont download. It says to check my internet connection – which I’m pretty sure is fine. So, obviously there’s something wrong with my computer and so I download hijackthis. If someone could help me out I really appreciate it:
