Motherboard won't work inside the case

[navaniharsh31]

My motherboard suddenly denies booting up ( for 1-2 secs the lights turn up and goes off ). When I remove the motherboard from my cabinet it starts working. Though this doesn't happen everytime. After reinstalling the mobo it starts working always and gives the same issue after a few days. What might be the problem? The motherboard or the cabinet?
Mobo- h110m
Cabinet- Circle CC819

I would check the backplate again for unwanted contact; you may also try some different case standoffs; they're generally available in two sizes.

Based on your description, I would suspect that there is a physical break on one or more of the traces on your motherboard. Less horrifying is the possibility that your RAM isn't properly seated: shut the computer off, unplug it, remove the RAM and then replace it in the proper sockets. Also make sure that all of the motherboard cables are properly and firmly seated in their respective headers.
