My Compaq dc7700 alarms when starting up

Hi all, my desktop pc will not start up. There is power to the unit but when i push the start button the green light comes on then immediately goes off. All three fans in unit spin for a few seconds then stop The bottom light, red, then comes on and flashes and alarms with 2 beeps every 3 seconds. These beeps/flashes continue in lots of two 5 times then the beep stops but the light keeps flashing in the same sequence. I have removed the cover and blown the dust from the internals concentrating on the heatsync but still no joy.

SOURCE: Hello,

This issue might happen due to RAM.

To resolve this issue:
Turn of the power supply for your desktop.
Please remove the side case on your tower(CPU).
find the RAM slot and remove the RAM from the Slot.
Clean the RAM terminals with the help of cloth or Eraser.
After cleaning place the RAM on RAM slot.
Now try to turn ON the PC desktop. If it is working thats fine or else you need to replace another RAM to check.

Please refer the below figure to find the RAM Slot and the lock to remove the RAM.

NO.

I sort of see your reasoning, but NO.
HP Compaq DC7700 Ultra-Slim Desktop PC, and Compaq Presario CQ62 series of Notebook PC DVD burner drive?

Until I compared both units I would have stated NO.

Now that I have THANK YOU. I just learned something,

http://www.amazon.com/HP-Compaq-DC7700-DC7800-DVD-ROM/dp/B004574PEG

Referring back to the photo view, of the Compaq Presario CQ62 series of Notebook PC's DVD burner drive shown, the REAR view shows the connectors for the SATA power cable, and SATA data cable.

The connectors use the same L-shape design, and size that a SATA unit for a desktop computer, would use.

Case design looks to be similar also.

I believe you are Correct.

Dear all we have a compaq dc7700 which does not start anymore. It gives blank screen, lfront led is red flashing and beeps 5 times. Can you tell me what is going on with this system ? Best regards


5 beeps for an AMI BIOS, which I think you have, means you have a processor error, or, in other words, the CPU.
Just to be sure, disconnect everything BUT the video, CPU, and memory. See if the result is the same.

Nothing happens when push start button. power cord etc good ??? is this a power unit failure?


make sure the outlet is recieving power

unplug the tower from the outlet & then replug it in & see what happens

make sure all cords are plugged in correctly in the back of the tower

then if nothing happens after you push the start button, power supply & cord could be bad

the same thing happened to my daughter's pc & had to replace power supply & shorted out the motherboard

When the power button is pushed on, the power button just does a quick flash and nothing happens. nothing starts on the computer.


have you added any new equipment to the system?
Have you have bad weather?
Do you have a suppresser on the AC input
How old might this unit be?
