normal debugging is to pull parts until the machine posts. Example, start by pulling video. Does the PC beep the nno video code? yes -- Then likely something wrong with video. no-- leave video out and pull memory. does the PC post now and beep no memory? yes - suspect memory, no pull somethign else. eventually you get down to MB, PSU and CPU. Then swap PSU first, then MB.

edit: it's not uncommon to have the PC post when you pull a part, then still post when you put the same part back in. I've had this happen with both a sata disk and a wireless network card. Memory does this a lot. Sometime re-seating the connector is all that is needed to get things working.
