Hello,
Recently, I got a new PSU and GPU, NZXT HALE82 N 550W and XFX 7870 to be exact. After wiring together everything, I went for the power switch and nothing worked! I searched everywhere and even tried the old setup, but still, nothing worked. I know that the new PSU is not faulty as I have tested it and it worked fine. I have tried everything from onboard graphics to trying to only connect the MOBO and video card. I have no idea what to do. If you need me to elaborate please tell me as I am in a rush right now. Thank you.

Hello, yes thank you for checking with this. However, I have read countless tutorials and checks for this. Let me tell what I have checked so far.

-Connections = working - I have triple checked every connection multiple times when trying to figure out the problem. Every connector fits and is correctly in place.

-PSU = working - shorted the 24-pin connector and the PSU started up fine.

-GPU = presumably working - I see no damage done to it and I have tried booting up with and without the GPU, both options resulted in nothing.

-Power button = working - I used a multimeter to verify that the connection from the power button to the MOBO was working, and it was.

-Front panel / panel_1 / MOBO = This is where the problem comes in. Just yesterday I tested the front panel and tried to short out the "pwrbtn" pins on the MOBO using a screwdriver. However, the computer did not boot and no sign of life from the MOBO, no lights or sounds.

Seeing that every other component is working fine, I guess my MOBO got damaged some how when I was plugging in the new pin connectors. Is there any way to verify that it is dead? If so, will I need to move my current CPU to my new MOBO when I get one? Also, I have an OEM machine, so will switching the MOBO make my license invalid?

Thank you,
