Reply: (edit)i had one where i could only get it to switch on by flicking the psu switch to kind of cause it to spark/arc inside. It was definitely faulty psu, replacing the psu cured the problem.

Reply: (edit)This sounds like a heat problem. Quite possibly within the new psu as Cobra suggests. With the power *DISCONNECTED* check inside the psu to see if clean. If not, blow out with a hairdryer set to cold and max blast. Use a long thin brush to assist. Also clean the psu fan blades if necessary. Are all fans in pc and psu working ok and blowing/sucking as expected. Were any heatsinks displaced during the move. Once pc fails you should wait for it to cool before trying to restart. Flipping toggle switch could cause damage. Advise how you progress. Good Luck - Keep us posted.

Reply: (edit)How about posting the system & CPU temps...that way we can rule out overheating. Otherwise, do you have another PSU you can try? What brand name is the 600W? Did you have it out of the case...if so, would you say it's heavy or lightweight? If it's heavy, it generally means it's made from better components & has decent heatsinks. Lightweight basically means the opposite. And a lightweight unit would be more likely to overheat.
