My new build not powering on. Need help.

Hey guys, so as you can see in the title, my new pc won't power on. Everything's plugged in, no cables are loose, and when i press the power button, it's not turning on. I even went back to the store and replaced the psu with a new one. It solved the problem for a week. And now, it won't power on again. What is the problem? Can the casing cause this?

Specs:
CPU - Intel Core i7 3770
GPU - MSI GTX 970 Gaming 4G
SSD - Samsung 850 EVO 120GB
HDD - WD Blue 1TB
PSU - Corsair VS 650
Casing - Aerocool GT-R
Motherboard - ASUS P8Z77-M Pro
RAM - G. Skill Ripjaws X 8GB

Update: I've been doing some reading and I've found out that my CMOS battery needs replacement. I've read the symptoms and I've found them recently in my pc. "New cpu detected", wrong time, etc. Will replacing the CMOS battery actually make my pc power on again?

Is your PSU getting enough air now that you mentioned casing? do you have any pictures you can take for us to see.

Okay. I'll go run to the store right now. I'm very near it. I will post the results right away.

Also have you tried the PSU test? where you take the 24 pin connectors and find a paper clip, shove one side into the hole where the green wire is and the other where the black wire is. Plus it into the wall and if your PSU fan spin that means your PSU is working. If it doesnt start up it could mean that you have a dead motherboard.

As it turns out, they didn't have any batteries. But even if the battery is dead, shouldn't the pc still boot up? I suspected a motherboard problem as well. But can the casing cause this problem? Maybe broken wires or something?

So when you got the PC it never turned on at all? what company did you build it from?
