    Have a Dell XPS Studio, the power button is yellow but it will not boot on. I unplug it and plug it back in, and still the button will stay yellow and not green. How do you know if its the power supply or mother board. Thanks.

    Can you see or hear anything else going on such as fans, HDD noises or beeps etc?
    Also, make sure to leave it unplugged for at least 5 minutes to dispel all static that could be in the PC.

    Obviously, the most thorough diagnostic would be to unplug all cables and components inside then try with nothing connected except CPU and PSU.

    The light tells you there is at least some power so the PSU is not dead (yet). I have seen this type of problem on other PCs before and it's usually the motherboard, but I've got little to go on, so can't be sure.

    Fans work and the dvd tray will eject. It just doesn't boot up.

    If everything fires up but there are no POST beeps, you see nothing on the screen and there's no hdd light activity (or is stays constantly on), the first thing I would check if the PC was with me would be the memory.

    For a fault with those symptoms, faulty memory or memory slot is often the cause although there's always a chance a Dell XPS Studio behaves slightly differently.

    Not sure how many sticks or slots you have but you need to try all possible combinations when checking ram. E.g. if you have 2 sticks and 2 slots, try 1 stick in both slots, if that doesn't work try the next stick in both slots.

    Just taking them out and then putting them back won't help identify a faulty stick or slot.

    Then you need to try stick 1 in slots 1, 2, 3 and 4 in turn. Then do the same with stick 2 and stick 3 etc. That's the only way to rule out one the 4 slots being faulty or one of the 4 sticks. Painstaking but necessary if you want to be thorough although you'll have a fair indicator by sticks 2 and 3.

    If none of the sticks work in none of the slots you'd have to say it's the motherboard.

    Well nothing worked. Is there anything I should try to savage before tossing it? And thanks for your help.
