My acer 19 inch DVI connector wont work!

I got the monutor about 2 weeks ago and the dvi worked fine. But I built a new computer desk unhooked everything to get it on the desk then hooked it back up and my dvi connector wasnt working since. I tried unplugging it restarting and everything and it wont work! Should I buy a new DVI cable??

Do they sell them at bestbuy?

Hmm I got the dvi to work but I had to completely remove the RGB adapter. Doesn't make any sense

Anybody know why this happened?
