New PC wont start

I received my PC today. After trying multiple times I can't get it to work. I have an older monitor HP w1907. It simple loads up into a blue/teal screen. I went out and bought a DVI-D cable. There are two DVI ports on the back of the PC. One can't find a signal, the other loads into the aforementioned blue/teal screen.

I then tried to use an HDMI and connect it to my TV's but no luck there either. One says it's not supported the other just simple stays black.

I don't know exactly what to do.

Any help with this frustrating matter would be appreciated.
