PC won't Turn on... AGAIN

Yea, I'm having the same problem with this new built PC as the last I had last week. I got a new motherboard (ASUS this time) and it works fine. The PSU works fine. The light is on the Mobo, but the PC won't turn on.

I'm thinking the actual CASE is broken, but was wondering if anything else could cause this.

NOTHING turns on when I press the power button. No lights, no fans, not even the PSU. I had the PSU tested last week and the computer guy said it was perfectly fine.

    One thing I would check for is grounding on the MB to the case. Sometimes those screws that you use to secure the MB and the insulators that go with them are off-center enough to cause it not to start. I always sit mine out on a counter-top or what-not and try to power it on there first, so that if it is DoA, I don't have to pull it back out.

    Then, if it doesn't power on once I have it in the case, I know it's a contact issue.

    did you build the PC?

    Check the plugs from the case to the mobo (power switch, HD led, etc). As long as I've been building computers I put them in backwards (positive on negative) at least 50% of the time. That's the first thing I look for when a newly built PC won't turn on.

    So it works when it's out of the case?

    Edit: In case the answer to this is yes:

    When you secure the MB to the case, make sure that you have those little felt rings that come with the mounting screws, and that they are lined up good. It helps to put one on each side of the motherboard as well. Additionally, you can pick up plastic mounting screws. They screw into the case, but have pressure clips on the top side, and the motherboard just pops right on them. Nothing else needed, and then you don't have to worry about insulating extra metal.

    yes, but I can't seem to get it to work inside. The gold screws that hold it, I can get one to actually inside the hold of the mobo, but the other 8 won't.

    I just realized something... I have the screws to let the PC no touch the case, but 2 of 9 have a special top so it goes into the MOBO and the other 7 do not. I think that's the problem

    If you are referencing what I'm thinking about. Here's the deal with that.

    There are different sizes of MBs. There are a plethora of holes in the case to put mounting screws. They are usually labeled in the case with A or B and sometimes a C depending on the case. Make sure to have the mounts in all the right places, plus, you may need to slide the MB closer to the back of the case to get them to line up.

    What you can do is unscrew all of the mounters and place the MB inside lined up, and check where the case holes are, perhaps mark them with something, so you can put the mounting hardware in the right spot, then pull it out, put down the mounts, slide the MB back in and then put the screws in. Those felt pads tho, if it came with them, use them. The ones that go under the MB are a PITA, but extremely helpful.

    I get mine from a local PC shop, any small computer shop would probably have them. However, if the mount screws aren't lining up, the plastic ones won't either, unless it's offset by just a tiny amount.

    As you have said that you've built these before, I'll assume that you have it in it's correct position and what-not.

    Here's a picture of the ones I'm talking about. If you aren't in a time-crunch, you can order them online at a number of places.

    Plastic stand-off's are the name

    Actually looking at the picture, there are two types, those in the picture slide into hold, and another type actually have the threads to go into the case.

    got it. Those two odd screws were doing it. I have no idea where they came from or what they are even for. Thanks for the help

    I would like to take the time to express that the EXACT same thing happened to me yesterday... you know what i did? unplugged the power stick from my wall and plugged it back in.

    my computer then booted up when i pressed the button.

    Obviously its a sign of the power gods not being satisfied with you. When was the last time you sacrificed an electronic to the Surge demon?

    No problem Kewop, always glad to help out when I can. It's kind of odd actually posting here though, I've been lurking for a real real long time. :)
