Re: HP compaq presario desktop wont turn on


    If it is four beeps and it keeps on repeating, try removing and gently reseating your memory modules( be sure and put them back in the same dimm slots. You should hear/feel a click if you have them properly reseated) and then restarting your system.The beeps are called POST (power on self test) codes. What is the model of your Compaq Presario? With more specific information we can direct you to detailed explanations on how to do this. Please read the very first post in this thread on how to ask a good question. It does help.


 Please keep us updated on how it works out.

Award bios beep codes are the hardest to diagnose.


Perform the steps erico suggested.


Award BIOS
Award states that they now only use one beep from there BIOS. This beep is one long beep and then two short beeps. This indicates a graphics card problem. Any other beeps should be treated as a RAM problem first and then the board sent in to be inspected.

The reason that the Award BIOS only uses the beep code for display problems is that it tries to display the error on-screen if at all possible. If the BIOS cannot initiate the display adapter then this causes the BIOS to make the beep code for a display error, which must be corrected before any other errors can be determined. Memory Test fails and hard disk failures etc will all be displayed on screen.

However people do say that they know what some codes mean some codes that I believe can be trusted are some while in operation. Consult the table below.

Beep Code Error
1 Long 2 Short Video Card Error - Either re-seat or replace video card
Repeating beeps Memory Error - Memory is either damaged or badly seated
Repeating Hi/Low Beeps Damaged or Overheating CPU
Hi Frequency Beeps Overheating CPU
