Hi All! I unplugged all my leads on my desktop computer to plug into another desktop computer so I could take some files off. Anyway, everything's plugged back into my other comp again and initially a screen came up saying something along the lines of "Your video ??? is plugged in the wrong port". It's a blue VGA lead think it's called, for the monitor. I have 2, a white lead and a blue lead (going to my monitor.) I then noticed on the back there are 2 blue ports which it would fit (so I unplugged it and put into the other blue port while it was still switched on) and nothing happened. Tried restarting my comp and (the monitor is on as well) it just stays on this blank / black screen and won't boot up. I've tried taking that blue lead out and restarting but it does exactly the same. Anyone know what the problem could be? Thanks!
