Multiple problems with an Acer 3820TG

Hey Guys, I have a brand new Acer 3820TG. Worked fine out of the box and then i ran Windows Updates. After restarting, something totally wrong happened. Here it goes:

1. I cannot run Windows Update anymore
2. Immediately after restart, if i press a key or use the touchpad the screen automatically dims and then I can't make it bright again by using the designated CTRL + Arows keys, as nothing happens
3. Cannot access network, nor by Cable or by Wireless. as it says that they are not active
4. Cannot access power options, i click it and nothing happens
5. Cannot access
6. cannot use Recovery from Windows as it says that there's a problem with the disk.
7. Overall system loads incredibly slow

These are what i managed to notice till now.

What can i do to make these right. I have pretty good knowledge with computers, tried a lot of solutions, like reseting updates, etc. Nothing worked.

The easy way would be to reinstall Windows, however i do not have a recovery partition on the device, nor a recovery disk included...

I am running Windows 7 Home premium.

Any help would be appreciated.
