PC not booting if motherboard is moved

Okay so I just built my pc everything is new but the GPU (Look at profile for specs) and basically I need to keep the mobo screws out because if the motherboard moves even a little bit, boom the system shuts off. I cant even correctly place the motherboard to line up with the standoffs without it not booting. Any help is appreciated. 

 

EDIT: There are screws under the motherboard keeping the bottom from being scratched. Dont worry.

EDIT 2: After messing with it for awhile I got a screw in the middle to keep the motherboard supported, it turned on and booted up windows but now after a few restarts it starts with all of the fans and HDD running but It doesn't load into the BIOS like usual nor does it show any video signal, Great.

is teh power button not doing anything at all? Sounds like a loose connection imo

 

If all else fails, take it all apart and put it back together.

It does work 1 of 3 things happen when I press it, 1. The system boots up normally all is well (this has happened 3 times) 2.  American mega trends gives me an error message telling me the chassis was intruded (Probably because the motherboard is out of place) or 3. It gives me a CPU fan error not letting me go on.

Is there something shorting out the motherboard like a rogue standoff? The only metal objects that should be between your motherboard and your chassis is the 9 standoffs that sit under the 9 holes in your motherboard (assuming your board is ATX.its 6 for mATX and 4 for mini-ITX) if there is anything else conductive in that space there will be problems

Well no not at all the thing is its currently off of the standoffs because it wont boot if it is on them and screwed in. I have no idea whats happening.

This reminds me of the old doctor/patient thing 

 

"my pc doesn't work when i hit it like this!"

"well then don't do that...idiot"

joking aside; check your standoffs, check your power cables, if your cpu can boot without a gpu, try that. 

and if all else fails, RMA the board

Have you tried testing the system out of the case to see if it works. 

Its shorting somewhere. If it has been a rogue standoff, there may be physical damage and your warranty is as good as dunny paper.

Check that you've run the outputs through the IO shield and nothing like usb tabs are going inside the port etc.

As mentioned ^^^ test everything out of the case on a bench/table. Double check every connection. & rtm if unsure.

Best of luck.

I think it has shorted once and is now just giving random BS errors because it's broken and doesn't know what to do, like with that CPU fan header error. Try RMA it my friend.

Yea I'm sure its shorted, I've tried building it outside of the case, I'm gonna get a bigger case so it can all fit with extra space. Thanks for the help!
