I have acquired a Dell Studio XPS 435T but something is wrong with it. If I know what then I would be happy to just buy the part and fix it however, I don't know what's wrong. All I know is when I turn on the computer it is not getting power. I have changed the power supply that came on the computer with a Rosewill RD500-2SB. So I know that the power supply is not the problem. But now I'm stumped could someone please help me or point me in the right direction. Thank you in advanced.
