I have recently moved to university and the day before I left my PC and monitor were working just fine. However after trying to set up the PC after the couple hour journey in the car, the monitor now says that it does not detect a signal. I've hooked the monitor up to my laptop and it then turns on, so I can only conclude that something happened to my PC on the ride over, a wire coming loose perhaps?
I've opened up the PC and every fan turns on with the power, however I'm not a expert and so I'm not going to notice if one wire has come out.
