Msi GTX 560 Twin Frozr II - Problem

Question

Hey folks,
Im having a problem with my Msi GTX 560 Twin Frozr II video card.
I can't make it work with my monitor, all I get is "No signal detected"
I know the monitor is fine, because I used it as it worked all good when I plugged it into
my laptop. It's a BenQ G2222HDL monitor btw. It has one VGA (D-sub) and one Dvi-D input.
So i've tried all types of cables (VGA, Dvi-D and even Hdmi cables), and
still, can't get no signal. What can I possibly do to make things work?
Also, my computer acts a bit wierd when it's starting up. Usually, I would turn it on, then it would turn itself off really quick. Then I turn it on again,
and it goes just fine and runs smoothly. After I changed the position of some RAM modules
and such, it changed. Now when I turn it on, the fans spin for 1 and there's just a tiny bit of noise until
it turns itself off. Then I turn it on again, and it goes just fine with all fans and stuff spinning.
So, I really need some help!

More background info; I build the computer myself. Everything went mostly fine, except for that I had to spend quite a long time to get everything right.
I started the machine, and it all went just fine (except for rebooting and then running smoothly, as it has done ever since). I did the MemOK! test and everything seemed to be fine. But when using the VGA cable that came with the monitor, I couldn't get any signal detected (I used a VGA to DVI adapter to plug the VGA cable into the Msi 560 TI videocard). I used 2 different adapters, but nothing happened. I tried with a HDMI cable, just to test, and that did not work either. Then, I figured out I should order a DVI-D cable.
So I ordered the cable, and went on to plug it into my monitor and my video card, no adapters needed. Still, no signal at all! Tried a different monitor to check if it was the monitor's fault. Nope, still no signal. Frustrated, I used the VGA cable again and tried to plug the monitor into the laptop, which worked just fine. A clear, bright image appeared. But not with my desktop computer with the Msi GTX 560 Twin Frozr II. Nothing works when I plug in the cables etc. No signal at all, although the computer itself seems to run just fine with fans spinning up and the different components making noise etc. Thus, I figured out there probably was something wrong with my Msi Geforce GTX 560 TI Twin Frozr II. Now I dont really know what to do.
Does anyone have an answer/advice/possible solution to my problem? I'm getting a tad frustrated now, seeing as I bought this computer 2 weeks ago and still haven't got to use it yet.
