    If it happened all of a sudden, your motherboard may be screwed. What brand is it?

    Is it under the HP warranty? I'd recommend taking it back to them. There's nothing I can think of that would cause that problem other than a motherboard failure.

    Lol you'd hope so, that being easier to replace, but I doubt it. If the front lights aren't coming on, there's something more serious that's happened.

    If you're not experienced with working inside computers, get someone else to do it, changing motherboard is one of the most complex procedures of all. Shop around and tell them you want the motherboard replaced (don't ask them to tell you what's wrong with the PC because they'll charge you a fortune for finding out - if the problem's the motherboard which I think it is, that'll be fixed by them replacing it, if the problem isn't the motherboard, when they test it after changing the motherboard the real problem will become apparent and they'll tell you what to do next). Don't just go to the first shop and ask to have it done, find the best deal. Some people are out there just to rip you off.

    Its not always the motherboard. And you better hope that its not the psu because it couldve fried other things with it. Open the case and see if their is any LED's lighted on the motherboard.

    Try clearing your CMOS by taking out the battery for about 5 minutes and putting it back in. You may get lucky.

    Do you have any fans that you can plug straight into the power supply (the large 4 pin connectors)? If so, try one, if it doesn't power up, it could indeed be the power supply. That could be good, could be bad. If you're not replacing it yourself, it's mostly bad because it won't save you time, and it certainly won't save you money.

    k no fans that are directly conected to psu. waiting for 5 minutes to clear cmos.......

    EDIT:
    another thing i noticed that my harddrive is not running when i power it on either.

    EDIT:
    and clearing the cmos did not help either.

    Can you unplug the data cable from the hard disk and leave the power cable attached, then power up the PC. If it doesn't spin up then we know the power supply is at fault.

    So it spins up when you remove the data cable, but not when it's attached?
