    Nothing we can do for you. You'll have to take it to the local computer shop then.

    I notice that you have posted the same problem three different times. Please list the components of your system. It might suggest a solution.

    That said, have you connected all the power connections on your motherboard? Let's start there.

    What are your PC's specs? What are your power supply's specs?

    It can be or PSU, or MOBO, or CPU. test them separate if u able to do that.

    could it possibly be the psu b/c before i replaced the old one it worked fine
    but the new one i replaced it with was brand new

    It's possible for even a brand new power supply to go bad. Do you have another you can hook up for test purposes?

    Hey there, I had the same problem with my computer. Hopefully yours doesn't need what mine did... I ended up replacing the power supply with a bigger one, and had to wait over a week to get it back from newegg... then once I got the new one, it ended up being the mobo that was dead. Had to wait another week to get that back... Once both were replaced, it worked fine. I would try replacing the power supply first, and if it still does it, the mobo. Hope this helps. -Dennis

    It won't post or boot without RAM so testing without it wouldn't tell you much about the motherboard, I think.

    XION is not the best PSU company. I have read reviews regarding them. Basically when you get a XION PSU. You toss it and replace it with something better.
