Hi my pc fail to start. it shows 5 red beeps - HP Compaq DC5800 Small Form Factor PC Desktop

check with CMOS problem,or dust in the Fan or check your RAM..

Hi, if your hearing a beep when the bios or pc is booting, there might be a hardware thats failing. Check this link as your reference: http://www.computerhope.com/beep.htm

1 short beep and 1 long beep Memory problem 2 short beeps and 1 long beep (repeats 5 times) Unable to initialize video or video card required but not installed 3 short beeps and 1 long beep CPU configuration error or CPU type is not compatible The following beep codes are common to many HP and Compaq desktop computers that can occur while restoring, flashing or updating the BIOS : Beeps Description 1 short beep Legacy floppy drive or CD/DVD drive not detected 2 short beeps Floppy diskette or compact disc not detected 3 short beeps Unable to start flashing (such as when missing a utility or BIOS image) 4 short beeps Flashing failed (checksum error, corrupted image, etc.) 5 short beeps BIOS recovery successful

Are they Long Beeps? Does the RED led light on the front show up?
If there is no RED led light blinking, then the problem is your RAM.
If there IS a RED led Light showing up, then the problem is your Power Supply.

It doesn't sound like an overheating issue, more of either a disc read issue or firmware issue.

Please try my following tip for re-installing the firmware. If this does not fix it then try cleaning the laser lens.

Failing that, if it is an overheating problem usually it will tell you with an onscreen prompt or shut down with a flashing yellow light

Step 1.

Turn your Playstation 3 off into standby mode (red light on)

Step 2.

Press and hold the power button. The Playstation 3 will beep when you first press it, then beep again 5 seconds later and then beep once more and turn off back into standby mode (red light on). You must now release the power button.

Step 3.

Press and hold the power again. The Playstation 3 will beep when you first press it, beep again 5 seconds later then there will be 2 quick beeps together. When you hear these 2 quick beeps release the power button.

Step 4.

Your Playstation 3 will now start up with a screen asking you to connect a controller via USB. Connect your controller and then press the PS button.

Step 5.

A menu will now be displayed on screen. Select option 3 "Restore File System". This will then ask you to confirm that you wish to go ahead with the system restore. Accept whatever the Playstation 3 says

Hopefully this will cure the problem on its own.

Hope this helps

Normally when a computer beeps repeatedly it means either you power supply has failed or *********** board, to test this get hold of another power supply that you know is working and use that one to boot your mechine, if you have the same problem then unfortunatly *********** board has failed and will need to be replaced. hope this helps

These beeps seem to show that your system did not detect any RAM (memory) modules connected to it. Please check.

1. Open the CPU case (turn the PC off first)
2. Remove the RAMs from the slot.
3. Turn ON your computer without the RAMs installed. Then observe if it gives the same beeps. If it is the same, then the RAMs might fail to register.
   
4. Try to plug in carefully the RAMs in place. If you have 2 RAM modules, try to test 1 RAM at a time to see if the combination of the 2 mess up your system.
   

hi

If it is showing the red light and continuous beep it shows that the battery is completely gone.

You can buy a battery and replace it by yourself.

Or get it to a professional to change the battery.

you need not replace the whole UPS its just a battery problem.

Thank you

pls try to use another compatible memory stick.

then confirm the status of your micro processor

i replaced one of the hard drives in my poweredge. how do i get it to copy from the good hard drive?
