I'm new to computers and don't know anything but I just got this PC and I can't connect my monitor to it . My monitor is a samsung sync master 912n , I connected my VGA to the back of the computer and nothing, my monitor just has a black screen.

My monitor shows the green light and works on my other PC but nothing will show up on my new PC . Please help me figure out what's wrong , thank you very much !

i5 3570k, asus p8z77-blk, corsair 600t white case, corsair hx 1000, asus gtx 660 2gb, 1tb hd, asus dvd rom.kk, corsair hx 1000.6 gb of memory 1600,
 
are you connected to the igp(intel hd 4000) or gpu (asus gtx 660 2gb)??
because your monitor can be connected only with rgb (d-sub) connector ...and on your gtx 660 there is no
d-sub connector.
if you have an adaptor like d-sub to dvi it will be do the job
