Q: I on my pc for a while and then all of a sudden my monitor goes black and says there is "no signal." My computer is still on, but the monitor won't turn back on if i move my mouse or power the monitor on and off. It only comes back after i shut off my pc and turn it back on. It turns off at random times, I could be on it for 10 min or 5 hrs. and before it does this. Why is this happening?
A: It could be the your graphics card is bad. Another reason may be that the graphics driver is incompatable. Or it could be that the monitor itself is starting to go bad.
