Hello,

I was trying to add a new DVD burner, and for some reason, when I
press power up the PC, the little light in the CPU board lights, but
when I press down the power button at the front, nothing happens, the
fans do not move at all. And the light at the DVD rom does not light
up as well. Then I unplugged the power supply to the DVD roms and the
harddisk, same problem. Then I tried to remove the graphics card and
tried power up. Nothing happens as well. Any ideas? Is it likely that
main switch has broken? Quite unlikely I think, since it was working
just before I tried to install the DVD rom. What other things can I
try?

Thank you very much for your help in advance
Regards,
Benson

Benson - some power supplies will not fire up without a hard drive
connected. I suspect you are looking at one of two issues:
1) New DVD burner is preventing power supply from starting
1A) Unplugging DVD burner and hard drive solved one problem, and
simultaneously created another. :) That is, power supply with bad load
refuses to start, and then power supply with "no" load refuses to start,
also.

2) Coincidentally, your power supply just died. Stranger things have
happened.

Suggestion:
Return the system to the EXACT hardware configuration that existed before
installing the new DVD burner. Carefully reinstall graphics card.
Carefully reinstall any drives that were removed, if any, prior to
installing the DVD burner. Make sure all your power connections to your
drives are firmly seated. Double check your master/slave jumpers on any IDE
format drives. When you are certain that your system is back to the exact
condition it was in before attempting to install the DVD burner, see if if
powers up. If NOT, unplug system from wall and walk away from it for about
15 minutes. Then plug it in and try again. If you can't get it to power up
with 'original' hardware, suspect a bad power supply.

BTW, if you get this system working again with the DVD burner nowhere near
the case, then return the DVD burner (RMA it as defective) -Dave

Reconnect the power button to the correct motherboard pins.

It sounds like your power supply unit may have failed. Or, while installing
the DVD drive in the case you unplugged one of the motherboard Power Switch
leads.
