my computer is permanently on . as i turn on the switch from main ac supply. my pc turned on. but it does not display anything. my monitor is ok. if i want to shut it down i can't. because power and reset button also not working. computer seems to be running perfectly but not.
Well first things first. If the Power and reset are not working then that means something is not plugged in rgith somewhere.
My suggestion is to unplug everything and check the button connections first to make sure they are properly put in place. then connect the PSU to your mobo and GPU and as well your HDDs.
Leave the DVD drive out for now. Then when you have verified all the connections try to turn it on with the swicth to the back of the PSU and then the main power button.
