PC monitor not connecting to tower
Just tried to link up my monitor and computer tower today, and it wouldn't work, the monitor was on, but said no signal.
i thought the lead might be a problem, the ones with blue ends, VGA leads that link the pc to pc.
so i therefore wet to the other computer in the house to try it out. Once again didn't work, but then when i put the other computers original ga lead back in, it turned on, but said no signal, just like the one upstairs.
so now i have two monitors that turn on, without any signal.
I stress that the other monitor was working perfectly before i took it out to test the other wire, so where exactly have i gone wrong?
all the pins are perfect, i tell you what, lets concentrate on this question first, why is a monitor that was working perfectly, now not working, with exactly the same wire in tower and monitor.
help would be greatly appreciated,
