Question about HP Compaq dx2000 Microtower PC Desktop

1 Answer

HP Compaq Tower

When switching on the PC, the unit just keeps on beeping and the red light (next to the green one) keeps on flashing. Read about the "PSU"- where is it and how can it be replaced? Thanks

Compaq Presario SR2020NX will not turn on at all. Any ideas, people?

ah a tower

you check the power source output
this can be replaced as a whole unit

at power up should be a beep
if the mother board is good it will start up its default
before loading from the hard drive

make sure the dust is removed from all the internals
clean all the contacts
the fans and cards and main board

Hello, When I power ON the desktop, It flashes a green light then after 1 second will start beeping with a red light. it beeps four times then pauses then beeps again for about twenty...

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.

Booting up

one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.
