Monitor works

Oh I'm so sorry to mention this ( or I did mention) but I have build in display and I bought a NEW graphic card and the monitor doesn't work when plugged into it, so in this case my new graphic card doesn't work since it gives no signal to monitor. But when I unplug from new installed graphic card slot into build display slot it works, which means that the monitor works. I'm using dvi to VGA adaptor for plugging my new graphic card into monitor. I'm thinking of buying a new dvi cable but it's hard to find because it's old.. So do you get my question? If not tell me and I'm really sorry if so

In bios I ( on boot up i press f10 and enter setup) and change the video adapter from onboard to pci-e slot so my computer well know where my graphic card is located. And yes my fan is spinning on my new graphic card but it seems to give no signal to monitor, it's really strange because It worked a day ago perfectly fine..

Hmm, you really think so? Monitor itself is the issue then hmm, I'm going to buy a new monitor then.. Oh sorry I think it's LCD 19 inch hp monitor year 2007 I think . I can't check because I'm in bed with an iPhone .. So what about if I buy the dvi cables and plug both VGA and dvi cables?
