to troubleshoot the Case Power-On button

remove the Power SW from the front panel connector which is plunged to connecter indicated RED

Then use a test pen or any metal to short the 2 connector(RED) to jump start yr mobo. if the jump start fail....is not the Power on button Fault

pls check yr 24 pin and 4 or 8 pin power connector is no loose

just done with a test pen, mb fail to start ? does this indicate a MB failure ? But why there power from the USB port to charge my hp ?

My MB is gigabyte GA-P55-USB3

GIGABYTE - Motherboard - Socket 1156 - GA-P55-USB3 (rev. 2.0)

Maybe only the 5v output is fine, others are not.

Does it make sense to bring the mb to gigabyte service Centre to test?

No....u back to square one..if mobo is tested working.....
most faulty mobo i tested so far.....will start but never post
as for faulty psu.... cannot power up the mobo...
so get a psu to test

Your tidying up might have caused some connection issue. Not sure your system has motherboard speaker, if yes then you should be hear the beep code. If you know how to reseat - RAM modules and graphic card, then do it.

Another question, does a faulty graphic cards affect the booting up of the PC?
