- Depressing power button does nothing
- PSU fan does not spin
- CPU fan does not spin
- Hard drive does not activate or spin up
Re-seated all cables and RAM on motherboard
No front panel lights activate or flash
!! Tested Power Supply with tester and it tests GOOD !!
!! AUX PWR LED on motherboard (inside case) glows amber whenever PC is plugged in !!
Removed front panel assembly that contains power button, light bars and 2 USB ports. This assembly has a ribbon cable that runs to the motherboard.
Depressing power button directly effects no change (compared to pushing button on front panel that has a plastic arm that presses this power button)
How can I tell if the ribbon cable or the motherboard is bad?
The cable appears in tact. The motherboard has a single AUX PWR light that lights when the unit is plugged in.)
Are there any other steps you can recommend to start up the PC other than by depressing the power button?
Are there other ways to test the motherboard?
I have removed all cards and drives except the main hard drive and 1 stick of RAM. No change.
