My computer is basically this http://www.dell.com/us/dfh/p/inspiron-546s/pd

Needed something cheap for me and the kids and this was it. Works for everything I need, or it did until this issue.

Monitor isn't the issue. I have two of them for display and both work with my laptop. I took out all of the ram and tested each one in the 4 different slots and still blank.

As for displaying anything. I cannot see anything on screen. There is no POST at all. I installed windows 7 on it about a month ago after having Vista 64 and didn't have an issue. I thought it might have been something with the USB ports since my kid keeps plugging in a USB microphone, but after unplugging that it didn't remedy the situation. I have since unplugged everything and tested it, but nothing is working.

Thanks.
