Does your monitor display no signal,if so,
If you're sure that the cable is ok, then the next most common cause of this is a loose graphics card.try reseating it & check for any loose connections,
do you see anything at all on your screen when booting up?My monitor is working on this computer so i know it works, shall i remove the card then put it back in ?
but i wouldnt i get signal through the motherboard display ?
yes, there should be a power connection,is that on your OS drive.possibly the connections come loose.No i dont see anything at all i know is rebooting because i can hear the pc shut off then start back up
also i just looked at the hdd and ssd connections and there is only a sata lead coming from my hdd isnt there supposed to be a lead from the psu going in to the hdd too?
