Dvi no signal, help

[NickVsYou]

I just got back from work and cleaned out my entire computer of dust and dirt and finally got the LED's in the case working, but when i get home i plug in my two monitors and nothing happens. So i keep trying, switching the ports that they were plugged into, making sure the power was getting to the monitors and it was, both monitors had power but no signal to the computer.

I then tried my small monitor, some crappy "Aopen" monitor that i picked up for 10 bucks, and it turned on and booted up. But when i plugged the other one in it still wouldn't work. So i need some help

P.S My second monitor is a brand new Asus 27" HD monitor, runs off of DVI.

What I've Tried:
Switching the ports that the monitors are plugged into
Trying one at a time, only the Aopen one works.
Taking out my graphics card and putting it back in


Please someone help <3

EDIT: I have a spare HDMI cable lying around, i tried using it but nothing showed up when i did, it's really pissing me off.
