I went on holiday for a week to return to my pc not booting up, all fans activate but hdd will not boot up and no boot screen,

When I finished work today I removed battery and shorted any remaining power, the pc started up, but when restarting pc it will not now start up.

My mobo is a amd pe-am2rs740g2 It's been a very robust pc I'd rather not bin it. As there is clearly a connection somewhere that is being an idiot.

Any help would be great please

Thankyou
