PC shuts down after 15 seconds

[The Boon]

So my PC recently has hit this wall, it will not load past this screen (I attached a picture to the post), this is a few days after replacing a fried motherboard. Had no issues up until this point (besides the mobo) being my rig is only a month old, temps were good, no under/over voltages, no short circuits. What I noticed too is the night before when I went to shutdown my PC before I went to bed is it was running in like an idle mode with the screens off after I shut it down (I assumed it was an update of some sorts finishing up) but my PC was still on the coming morning, when I noticed that I wiggled my mouse and pressed a few keys on my keyboard to see if it was in sleep mode. It wasn't responding so I hit the reset button, as soon as I did that this issue appeared. It has the asus load screen to enter the BIOS yet I hit delete or f2 it won't allow me to enter the BIOS. And as soon as that screen appears my PC shuts of exactly 15 seconds later just as it says on the screen. I've already tried pulling out the mobo battery to reset the BIOS. I even replaced the battery, I've tried unplugging the case usbs and keeping everything USB related unplugged except for my HDMI and dvi plugs for my screens to see if that was the issue (read that fix on another forum) and still no luck. I'll list my specs incase there is a known issue between components that is causing my new build all these problems. And I appreciate any input anyone would have to help me fix this! 

 

Specs - aus z170-ar, Intel i5 6600k @3.5ghz, gigabyte  radeon r9 380 4gb w/windforce, 16gb of crucial ballistix ddr4 @2400, liquid cooler (not sure if this matters) corsair H55, corsair cx750m, hitatchi 500gb HDD, Toshiba 1tb hdd, and some random $20 LG optical drive (lol). 

 

Thanks, Brandon

Try plugging in a keyboard

Already tried that after I tried the no USB devices idea, still wouldn't let me into the BIOS.

What fried the last motherboard, Could it be possible that your PSU fried your motherboad? Have you tried changing USB port for the keyboard, or better yet a different keyboard?

I have been hearing bad things about CX series corsair. Just did some googling and it seems like other people are having trouble with that series of Powersupply. Maybe it is not to late but i would get a different PSU and see what happens.

Not sure what fried my last board. Guys at micro center said return the one I had and see if that fixes it and it did. Assuming a bad capacitor on it. And I failed to mention as well, my Windows 10 was attached to my old board on my old build, I just used the HDDs from it. Thus having a watermark saying activate windows. Could it be just me needing a new windows disk to install cause my "demo" period is up and requires a copy to boot up? I'm assuming prob not because I can't even get into my BIOS to check. But I'm not 100%

I still think the PSU could have fried the last motherboard by putting to much voltage to the capacitor. A volt meter would be cheaper then a new PSU but I still think that the psu is the problem.

I'll def look into it, thanks. What do you think it's doing to my build to cause this though? Not enough power to the HDDs? CPU? Mobo? Or something else?

I think it could be sending to much power to the motherboard. Here is a straight PSU tester

Thanks man! I really appreciate it, hopefully it's just as simple as buying a new PSU. When my other board fried I thought it was the PSU that died so I bought (and returned when I realized it was the mobo) the evga 750 g2 gold PSU. So I'll prob just end up going back to micro center and replacing the cx with that thing so I can actually enjoy my new rig lmao.
