When your system freezes up or gives you the blank screen of death, do not panic. Follow these simple steps:

  1. Take a deep breath.
  2. Write down the last things you did immediately before the disaster. Try to remember as much as you can and be as detailed as possible. Include any information from any error messages you can remember. 
  3. Call us at 847.675.3513.
