Screen not responding
I was cleaning my computer from dust the other day and after I finished I tried to turn it. Everything went quite well except the fact that the screen didn't show any image. So I thought that maybe the there is a problem with my screen so I brought another screen and plugged it to my computer ,but it still didn't show any images and when I turned it on it said "no signal" and turned off again. I checked if I maybe unplugged any cables while cleaning my computer but everything seems connected. Do you have any suggestions what the problem might be?
