What have I done wrong?!?
My computer room is getting decorated, and so I moved all my computer stuff out, disconnecting the things from the computer (ie. monitor, keyboard, mouse, printer etc.) and carrying them to the room as I went along. When I had carried everything back into my room, I reassembled it. Admitted, I have little experience hooking things to computers - but I think I did it justice. That is, until I turned my monitor on, and it complained of "No Signal." I made sure all connections between monitor and computer were OK, and secured in the wires, but that made no difference. I also tried a different plug. When I take the cable out, it recognises this and says "cable not connected."
Power is definitely going to the monitor though, and it is plugged in. My monitor is 18 months old, like my computer and is the AOC LM725 LCD monitor model. Help would be really appreciated. Computer's on, no response from monitor.
I'm on Windows XP SP2.
Thanks,
Connor.
Answers:
Normally that is because the monitor is not plugged in properly. Check if it is well connected. If it is well connected, try another monitor. If it does the same thing again, the "No Signal" message indicates that the monitor is working but the computer is not. Your monitor is not gettting a valid signal from your video card.
You have either knocked a component or connector loose, or have moved a connector from where it should be. Possibly you have done both!
You need to consult the motherboard manual for your PC (or download it from the motherboard manufacturers website if you haven't got it) and check that all wires and connectors are correctly attached to the appropriate pins.
You then need to check that all expansion cards and cable connectors are firmly and securely pressed 'home' in their sockets.
Good Luck!
pls contact a hardware mechanic if u have no expirience of assembling computer parts. i think u should not take risks in imporant things like this
Double check to make sure that you do not have 2, count them 2, monitor connections on the back of your computer. In my early years it messed me up too!
1. confirm that the power supply/rating is not the problem . 2. ensure that the data cable of the monitor is well fixed to the computer.and that you dont turn it ( the cable ) up side down . 3 ..finally , try another monitor . good luck .
