When I plug my computer in and hit the tower power button, the fans and the hard drive fire up, but nothing happens on the screen (it's blank) and the monitor's power led flashes yellow on and off. The usb wireless mouse receiver doesn't light up nor does my (wired) keyboard num, caps, and scroll lock light up. What is going on?
I have tried switching monitors as well as confirming that the monitor connector is firmly attached. When I detach the monitor, the 'check signal box' comes up on the screen.
I have a Dell Dimension B100
I just returned from vacation and my computer worked fine when I left.
I hope you all can help.
