Hi BabyPhat, hopefully its ya monitor and not ya computer. Since you said you got four squares with green.. blue.. red .. etc. The monitor seems to work just fine. May be its ya computer..? So, borrow someones monitor and then check it see if that works fine. If it does then its your monitor.. if the new borrowed monitor gives you the same problem.. then its your computer thats not working. Hopefully you'll troubleshoot it with ease. Later
