Solid Green light on motherboard but PC won't power up, help?

[Sticky_Keys74]

Hey, so I just had a hurricane occur but my device was unplugged. I later plugged it in to a generator and it was working fine. I turned off the device successfully and unplugged it before the power supply was cut. I have power now but my device fails to perform any functions other than turn on the solid green light on the motherboard, I've followed procedures like unplugging the  device and holding the power for 10 seconds but they have all failed. I have switched out the power supply, and that too has failed to get any progress. I have considered getting a new motherboard but with the nature of my device it may prove extremely difficult if not near impossible. Any ideas on what's going on and any possible solutions??????

Hi Sticky_Keys74

Did you have your PC connected to an UPS when you connected to the generator?

It sounds like a power surge may have taken the mainboard out. Any fans spinning?

You have tried a known good replacement power supply with no luck. Pull the MB CR2032 battery for about 10 minutes to reset CMOS.

Additional steps you can take to try to locate the faulty component.

Run the PC barebones (disconnect all peripherals except the monitor).

Disconnect all SATA drives. Remove the RAM to see if you can get a POST error message.

Remove the graphics card (if applicable). Try integrated graphics or add a graphics card if you are using integrated graphics.

Again, sounds like a mainboard, or any component on, or connected to the mainboard, has bit the dust (most likely a power surge or spike).

You would have to swap in known good replacement components one at a time, which would include replacing the processor and the motherboard, to get to the bad component.

Best option is to have a local PC tech take a look.
