Question

when I turn my computer on it won't boot up correctly. the powere light is supposed to be green but it is orange. there are no beeps to let me know there are any problems with the post.I looked at a website for IBM BIOS and it says no beep (no power, loose card, or short). the cards are not loose and it seems to have power but the short is a problem I don't know how to check that.
