i've just installed a new motherboard (asus a8n) and cpu (opteron 144) in my old rig because the mobo was faulty (ide port didnt work).
now it wont boot up (it doesnt beep or post), everything comes on but the monitor just displays no signal input and then goes off and the HDD led just stays on for a second and then nothing???
the dvd drive opens and closes still, can anyone help since i've no idea what to do?
