Answers :

Try your monitor on other desktop or laptop, if the problem persist - change the monitor or borrow one and try it on the same computer as it could be your video card. hope this helps...
I am going to assume you already checked the monitor on another machine and it worked. So if you look just under the assorted flash drives there should be one or more tiny illuminated number from 1 to 4 that appear. Ex. 1 2 or 1 or 2
\015\012 3 4 etc. after you obtain the number or numbers that appear there they contain the exact inargumentable cause for the malfunction. for example a 3 and a 4 indicate one thing & say a 1 & 4 mean something else and so on. The simple solution to each numeric code can be just as easily found in the Dell Deminsion 3100 User Guide found here in this FixYa sites links to user guides & manuals. when you click on it a pdf appears. Look in the context for the page that translated the unit self diagnosing error codes and follow the instructions on how to fix it.
