Hi Octane, If you?re not getting any beep codes then something real basic is wrong. To start off I would check the following: -check the new power supply and ensure it is designed for your motherboard. -check the power supply connections to the motherboard, the connectors should mate up exactly to the motherboard connector. -check for shorts (mounting screws against capacitor leads are common), correct grounding and so on. Any of those can cause the same symptoms. -test the power supply in another computer or if not available you can generally pickup an inexpensive tester for $10 to $15 at a computer store that sells parts. -make sure your motherboard is designed to accommodate your processor. I would expect a beep code for this but you never know. Let us know how things go and please don?t forget to rate the posting.
