Hi guys I need some expert advice, recently my PC stopped working. It turns on and all the fans and tower lights come on but no signal gets to the monitor and no power gets to my mouse or keyboard via the USB ports, I checked all the connections in the tower and tried to reset the bios but no luck and suspected a motherboard fault so I took it to a local repair shop for further testing. They ended up telling me they think the motherboard is faulty but they would need to replace the CPU also as they could not get a motherboard that would fit my CPU from there supplier. I thought I would check here for advice as this seems a bit strange, could I not just replace the motherboard my self to avoid buying a new CPU? Here are the specs of my tower http://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03513449 any advice on this matter would be greatly appreciated.
