Screen issues

Hi.
Today I started up my hp 2000. It started up fine with the welcome screen on it. But when it was supposed to load my desktop, it was only a blank black screen with no wallpaper, no taskbar and no icons overall. The screen isnt broken, the laptop it self is only a year old, with no damage to the hardrive,ram etc. The keyboard doesn't respond so i cant type or even start task manager. I installed new start orbs from devianart.com It was after that when i tried to change it using button changer for windows 7 v.5 that the taskbar disappeared and the icons but the wallpaper was still there then. After i restarted it was a blank screen but the keyboard responded but nothing else. I managed to open internet explorer through task manager and use it. But after i closed it the keyboard did not respond. Now only the mouse works. I tried to access a restore point that i had made that day through control panel but control panel wouldnt open. Please help me. Im almost in tears right now because that is the only working laptop i have.
God bless you for your time
Thank you
Note: There is no sound and i cant control or adjust it.
Note: Please help me Im a student and have science exams soon.

If you don't have a password, just leave it blank and continue.

If that fails, visit the following link for more details;
