Thank you so much for your reply. The computer is a Dell 8250. I would have to look it up to see what video card they put in. I've taken it apart several times now and checked everything. I'm sure I plugged all the PS plugs in where they were. Could that be the problem if one is not plugged into the correct place? The codes I get are yellow, green, yellow, green.
Thanks again for any help you might be. Have a great fourth.
