Second monitor isn't working/isn't detected

I recently bought a second monitor (lg e2351). I proceeded to connect the new screen to my second graphics card via DVI cable. Wouldn't detect it. I fiddled with some things and ran a graphics card update and it found my second monitor. During the night windows did an update and restarted my computer, now I cannot get the second monitor to work (be detected) at all. The second monitor works (i've connected it to my top graphics card and it works) but I cannot get both to run at the same time.
I'm running windows 7 64 bit, I have 2 radeon HD 5750's in crossfire. Both my monitors are connected via DVI cables. The primary screen is connected to the top graphics card, while the secondary one is connected to the bottom card. Whichever monitor is connected to the bottom card doesn't get detected.
I have tried forcing detect via the ccc and screen resolution but to no avail. The second monitor only showed up that one time (and worked for like 3 hours while i used it) and I haven't been able to get it working since.
Any help would be appreciated.
