PC won't start ... Motherboard LED on
power switch header
HP dc5100. PSU is working and tested, motherboard led is on. Tried different cpu's, pressing the power switch power led goes on but nothing happens(power led goes immediately off). Tried pulling the bios battery out resetting the bios, makes no difference. Yet i noticed on the same pin header unit together with power switch there is a transistor connected (which i never saw in any previous pc model before). Seems its base and emitter are being shorted. Could it be transistor failure the reason pc is not starting, could i rid of it somehow or try replacing it? thank you
