Build problems

I am rebuilding my edit system and cannot get system to post or do much of anything.

When I installed the graphics card and booted all I got was a high pitched whine or continuous tone. I pulled the card out and booted and sound went away.
Tried my old power supply but still same sound.
Tried the Geforce 260 in my office computer and it made the same high pitched whine, but maybe it is because power supply is only 500watts?
Tried installing the GeForce 9500 from my office computers in the new one and still could not get it to post.
Tried removing all but one Dimm.
Disconnected the hard drive and cdrom.
Still will not post.
Unfortunately I have had all this stuff for about a month and now my 30 days return to New Egg is up tomorrow. I don't Know what to send back.
Anybody got any ideas?
