You will need to give us a lot more information before we can truly help you.
But have your tired to get into the "Safe Mode"?
After you first turn on the power button, keep tapping the F8 key until you get a startup menu.
Then using the arrow keys, select the "Safe Mode" option.
The computer should start in a limited (safe) mode with access to your system.
Then go to START - All Programs - Accessories - System Tools and finally to System Restore.
Choose a restore point from a date that the computer was working. Follow the on-screen directions.
Let us know exactly what happened.
Also provide your computer make and model and what you were doing before it left you blank.
