one last qustion. did you move the desktop from its original position.

Customer: replied 1 year ago.
No
Expert:  Michelle replied 1 year ago.

We have to diagnose the problem for that you will have to remove the side cover, facing the front remove the left side cover. Please note power cable must be only unplugged and please take prior shock hazard precaution. I will walk you through you would need a philips screwdriver as well.

This will take a few minutes, I will need to disconnect cables to move the computer before attempting to remove panels.
Expert:  Michelle replied 1 year ago.

Take your time.

Customer: replied 1 year ago.
OK, side panel off.
Expert:  Michelle replied 1 year ago.

Customer: replied 1 year ago.
No beep codes, as far as I can tell. Does not appear to be a speaker and headhones are USB.
Expert:  Michelle replied 1 year ago.

there is a beeper inbuilt on the mother board you dont need a speaker to get that beeps

Expert:  Michelle replied 1 year ago.

if you dont get beeps codes when the memory in not installe that means there is a problem with the motherboard.

Customer: replied 1 year ago.
No beeps.
Expert:  Michelle replied 1 year ago.

Again, no beeps.
Expert:  Michelle replied 1 year ago.

No Beeps No Power, Loose Card, or Short.

Customer: replied 1 year ago.
Fans turning, CPU fan turning. Red light on Motherboard lit, blue LED on CPU mount lights shortly after fan starts for CPU.
Expert:  Michelle replied 1 year ago.

I have told you the best possible way to identify the motherboard without a diagnostic pci card and to check on which part of the motherboard is bad you would need a 4 digit diagnostic card which will tell which part of the motherboad is bad on dead.

Expert:  Michelle replied 1 year ago.

Fan no cpu fan runs and flea power on the board comes up on directly from the power supply of the computer if there is no beep codes present on when you turn on that means there is a problem with the motherboard in some section.

Customer: replied 1 year ago.
We are not getting any sound, but the bot***** *****ne is that you think that the problem is with the motherboard, correct.
Expert:  Michelle replied 1 year ago.

absolutely correct, as i said earlier you dont need a speaker to be connected as it already has an inbuilt beeper on the motherboard itself.

Customer: replied 1 year ago.
the beeper is part of what is not working.
Expert:  Michelle replied 1 year ago.

yes its a hardware component which is inbuit on the motherboard.
