Boot Issues - New Build

When I try to boot up my new build it will, depending on some CMOS settings (not sure which) either boot with:

"Verifying DMI Pool........." And then hang or
"Verifying DMI Pool......... Update Successful" Then hang

If I try to boot from Windows Install disc, then it hangs on:
"Boot from CD/DVD"

I have checked all the connections, all the drives show up correctly on the CMOS as does all the RAM. As does the graphics card and CPU.

HELP!
