Having problems getting my monitor to get a video signal

[daniel5383]

Hello,
I recently bought a used pc off of ebay, and it came today. I went to plug it in and it turns on, fans turn on, green light...but no video signal...I tried hooking up to 2 different monitors using 2 different vga cords, 1 dvi cord, and 1 hdmi cord and nothing...So I had a geforce 9500gt in another pc that i know works for sure and just installed that, and still nothing. The specs on the pc I just got can be found here

HP Pavilion p6720f Athlon II X4 840T 2.9Ghz,6GB,500GB,amd radeon 4200


I dont know what the deal is as I am not that good with pc's. The seller on ebay has over 10000 items sold with 99% positive feedback. So could it have been damaged being shipped. Or am I missing something here?

If anyone has any explanation on what could have happened or any kind of solution, it would be greatly appreciated. I came here because I thought I would get some quick help. I have contacted the seller and theres no telling when I will hear back from him.Thank you.
