Okay so here's the story, a friend came to me with an emachines T2824 desktop which wouldn't power on anymore, after a little diagnosis of the power supply and all peripherals I concluded that the motherboard was shot. So I ordered a new Biostar P4M80 from Newegg, after installing the new mobo and hooking everything up, it posted and booted just fine and I got into safe mode so I shut the system down and proceeded to connect the HDD Led and Power LED to the mobo and finish putting it back together.. Now all the sudden it won't post anymore. Fans are spinning, drives work, but no keyboard lights and no video signal! I've tried swapping in a compatible CPU and PSU, tried booting with just CPU/Ram/HD and still no post, no beeps, nadda. Even tried clearing CMOS, no luck.. Any ideas or did the motherboard just randomly fail? Power was disconnected while I was messing with the LED connections so I know I didn't short anything.
