When the computer is started, the hardware run an automatically test for errors on the components. This process is called POST(Power-On Self Test). When the test is running, if errors are encountered, these errors are expressed through a series of audio beep links or display a code on the screen. With this code you can determine what part of the system has problems and you can start work on a solution.
The code:
1 audio beep – Everything is OK
2, 3 or 4 short audio beep - This problem can be solved only to open up your computer and pull out the RAM chips. It’s very important that the RAM chips to have the same speed and type, because in time it’s possible that this differences of the speed and type to affect your computer.

Whether I choose to boot up in safe mode or normally I end up with the same result: a black screen. I tried restoring the system but I get the following error message (my pc is French so this is a rough translation): No restauration point has been created on the computer’s disc system. In order to create a restauration point please create the ‘protection system’. When I click on ‘protection system’ I get the following message: Your computer is functioning in a limited diagnostic state. If you use the restauration system in this limited state you cannot cancel the restauration. The help rubric is not available in this state. I can’t get beyond this point. Needless to say I have no back up discs nor a copy of Vista. Some advice in how to proceed would be much appreciated!
