When I turn on my Acer I get no signal on my screen. I have replace the cord for the viedo connection and that wasn't the problem. I put in a new hard drive and that wasn't it. Now everyone is telling me it my viedo card that needs replaceing. I don't know where it is in my computer and is that something that I can replace myself?
do you know if the monitor is in good working condition? Have you tried another device on your monitor? If the monitor is okay then you can try replacing the video card although that may or may not fix your problem.
