SOMEONE PLEASE HELP!

HI
I wanted to try the SUPERantispyware in my
computer to check for malware. I was sleepy and let it run the deep scan all night.
The scan was done and it found around 346 objects.
In the morning I clicked on save report and I scrolled down clicking on all the small squares next to the processes or whatever it is called and then I clicked quarantine.
It quarantined everything and I got a blue empty screen. I booted the computer and all I got was a blue screen. My desktop desappeared and everything.

I turned it off again manually since I don’t have the word start
on the screen. I started it in safe mode presing f8 and I saw a lot of
words that desappeared right away and then I saw the Windows
Advanced Options Menu, Please select an option.
I clicked on the last good configuration and enter. I got the Windows
screen with the password slot. I wrote my password and It gave me
a blue screen. No desktop, no start button, no time. NOTHING.
FINITO.
I did it again selecting safe mode, then again selecting reboot and again
selecting last known configuration. It kept on doing the same thing.
It gives me a screen with a slot for my password and when I write
it down it says “loading your personal setings” and then it gives me a blue
screen with nothing in it. No icons, no start, time clock. Nothing.
Which of this commands should I select this time?
Windows Adavanced option Menu

Safe Mode
Safe Mode with Command Prompt
Enable Boot Logging
Enable VGA Mode
Last known good configuration ( your most recent setting that worked)
Directory Services restore Mode ( windows domain controller only)
Debuggin Mode
Disable automatic restart on system failure
start windows Normally
Reboot
Use the up and down arrow key to move the higlight to your choice

Did I quarantine every file in my computer?
Did I lose my computer?
Help, Please
