My custom built PC used to work fine, I got a new case and now it doesn't turn on. What's the problem?

I've recently bought a new case (CiT Vantage Type-R Gaming Case) for my custom built PC because my old one was cheap and low quality and I just wanted an upgrade but that's beside the point. I took all the parts out of the old case and carefully assembled them into the new one and it was all set up. I pressed the power button and the thing doesn't make a single sound. I even tried bridging the two power pins with a screwdriver to try and do it without the button on the case but that didn't work either. So I decided to take out all the parts and try to breadboard it on the box my motherboard came in. Graphics Card, CPU and RAM all installed, I try to turn it on and strangely the fans spin up and their is a display on the monitor. So I put all the components back in the case thinking it will work now but theres still nothing happening but what confused me was that the standby light on the motherboard was on while it was in the case so there is power running through it but nothing will turn on. Could the case be the problem? The problem definitely isn't the components since it was all running fine an hour before in the old case. My motherboard is an ASUS F2 A55-M LE. Please help. Thanks.

Hi. Did you install the Standoffs in the case before you mounted the Motherboard?

Yes I did

If it is POSTing outside of the Case, but nothing when you put it in the Case, then it is grounding out somewhere in the case.

How could I resolve this?

make sure the metal io shield finger is not shorting out the mb. make sure the cpu heat sink not hitting the mb back plate and shorting out. make sure your case fans are not shorting the system or the usb front case plugs.

whats the io shield finger?

coastie65 · Oct 16, 2013

That is the shield around your USB, Audio and other ports on the Motherboard, and I hope you changed it when you moved the board from one case to the other. It would have to be removed from the Previous case and installed in the new case, after removing what is in there. Those have fingers or clip like things on them and that could be shorting things out.

Yes I'm using the shield that I was using in the old case. Do you think if I remove it will resolve the problem? (because i dont really want to unbuild the whole thing just to find out that I didn't need to) also would any of my components be damaged by this short?
