The first things I would suspect would be the memory and power supply. Power supplies seem to be a constant source of trouble. You would think a computer should last more than a year before having problems. Is it still under any sort of warranty? Also research the beep codes. They may be telling you exactly what is wrong.

When I attempt to boot the unit, no signal is sent to the monitor or keyboard, nor does the green light next to the power button turn on. The amber light does not, either. The fan will run at high power...


I had the same problem with my computer and the Compaq-HP techs told me to pull the ram out and then put it back in. They called it reseating the ram.
This fixed the problem i had. Try this and good luck.

My monitor has kicked into sleep mode and won't "wake up".


Unplug all the Cables from Compaq Presario 5103 CL and leave the Keyboard, mouse and monitor cable pluged in.

Now make sure the power cable of the monitor should be pluged in and the power cable of the tower should be pluged in.

Now to check if the montor is fine just unplug the video cable only which will show no input signal on the screen. If it shows this signal the monitor is fine. Plug back in the video cable.

If the monitor is going to sleep mode it might be possible that the old computer ( Compaq Presario 5103 CL ) is in stand by mode. hit any key on the keyboard and it should come back .

If it is not in the stand by mode then do one thing. Check the same monitor with the new computer. If it is working. Perfect ..!

Do one thing now ..!

Unplug all the cables from your old system and then press the power button for 30 sec and let it go. Now plug the keyboard, mouse and the monitor try again.
If it works Perfect. If not ..!

Then you need to open the tower and check on the processor FAN is it running..? If its not running you will not get the display as the fan is responsible for the display on the screen. Otherwise...!

Check the Tower possibly the Tower is not getting the power.

Try these steps and let me know If it works

My compaq desktop has two long beeps a pause and two long beeps without a signal to the monitor. If I put a recovery disk in it beeps normally but still no screen.


Sounds like a video adapter problem. Try taking your video card out and then reseating it into the PCI slot. Make sure your monitor is connected correctly. Also, it might not hurt to make sure the all other periphs are seated correctly. (RAM,Network card, etc) hope this helps

Blank screen


When you say "When I turn on the computer the monitor acts like it is getting no power", do you mean the light on monitor doesn't come on or it does and it states it has "No Signal"? If it says no signal then it is receiving power just no signal from computer. What kind of connection is it? Digital(white) or analog(blue)? Is the keyboard wireless or is it PS/2?

If the keyboard isn't wireless and you're plugging the monitor in correctly I would say it's a power supply issue. Try changing the outlet you're using and/or bypass the surge protector to plug directly into wall.
