Totally non-sense making crazy laptop problem

[peppermintyuki]

First, hello!
Now, to my crazy problem.
This morning when i went to sign into windows live messenger, i got an error code saying i couldn't sign in because of my firewall blah blah blah internet connection blah blah blah.
So I checked the internet connection, and its fine... until i try and sign into anything. As soon as i click "log in" on hotmail, yahoo, myspace, facebook, you name it, it comes up saying internet explorer cannot display this page. The same is true on goggle chrome and firefox.
I've turned off my firewall, turned off all the protection i have, changed my internet settings, done everything the windows live messenger help section told me to regarding that error, restarted my laptop, restarted my modem and router......
And nothing.
HELP ME BEFORE I KILL MY LAPTOP PLEASE

Are your windows updates up to date? ........What firewall is used?.............If you get another error code make a note of it.

[peppermintyuki]

Updates are current, firewall is windows defender but its off now... the error code for windows live messenger is 80048820 and thats the only error code i've gotten all day

Unless you've done so already have a look here...

This is a common error.

Google 80048820...tons of hits.......Avoid the sponsored links on the rt hand side of the Google search page ...... they are unsafe.....Don't run without a firewall.

The only thing on there i havent done is changed the time.... which i'm now working on doing.
But still, i cant view any secure websites on my laptop.....

Windows Defender is not a firewall.
Why did you change time??

[peppermintyuki]

Windows firewall then, whatever its called.
I changed the time because it was a few minutes off and apparently that can mess up msn.
Also, since yesterday I've reformatted my hard drive, and it still has the same problem, so maybe its something with my internet? But the other computers on the network are working fine....
