I unplugged everything from my powerstrip to wipe some dust off of it, and when I plugged it all back in, my computer suddenly decided not to post. When I plugged the PSU cable back into the powerstrip that was already turned on, my PSU switch was also turned on (this might have been my error). Immediately upon plugging in the PSU cable to the power strip, the computer started to turn on, but never posted. I never actually turned the computer on, it just did it itself, and then turned itself off suddenly after all the fans/lights/HDD spun up.
My current theory is that I either shorted the PSU or the motherboard, however, I do not have any parts available to me to confirm whether or not my PSU is the problem. Whenever I turn on the computer, I get no beeps. However, at the bottom of my motherboard (Intel DZ77GA-70K with an i5-3570k) there are little lights showing what the computer is doing, When I initially power it up, the activity light is blue, but then turns off. "CPU INIT" turns and stays green, as does "MEM INIT." The lights next in the series (Video Init, USB Init, HD Init, Opt Rom Init, and OS Start) do not light up at all.
So far I have:
1) Taken out everything except CPU and RAM, no change.
2) Taken out both sticks of RAM (2x8GB DDR3 1600MHz Corsair Vengeance), and got the beeps for not having RAM, and "Mem Init" did not light up
3) Switched out the RAM sticks in all the different slots, "Mem Init" lit up, no change
4) Reset the CMOS
5) Drained remaining power by holding down the power button
6) I've been using the power and reset buttons built into the motherboard. Once I turn it on, the only way for me to turn it off is to hit the reset button and once it powers down, flip the PSU switch.
I'm fairly certain it isn't the RAM or the CPU since they're both lighting up on the motherboard, I checked the RAM, and the CPU does heat up the heatsink (Hyper 212 EVO). This isn't a problem of insufficient wattage since I have a 1050 Watt Corsair PSU and my system probably pulls 600ish.
Since I did nothing different, I'm fairly certain whatever went wrong did so when I plugged in the computer with the PSU switched on and it turned on without posting/turned itself off. This would be very easy to just check the PSU if I were near my family's computers (which I also built) and tested them with their tried and true PSUs.
Basically I'm just hoping that one of you guys have had this happen or something and can tell me if its my motherboard or my PSU since I'm convinced something shorted and is actually broken. If there are any other things that I haven't done yet and a part might actually not be broken, or I can isolate the problem, please let me know. I want to be able to RMA the broken part ASAP because not having a computer is killing me and I want to be able to play the Division Beta that I have been waiting for for months. If it's my motherboard I might just cry since it's third gen and even though I purchased it at the end of Feb 2015, I will likely have problems doing an RMA since I doubt Intel has any laying around anymore, so fingers crossed it's my PSU since I have another 3 or 4 years on the Corsair warranty). Thanks for the help!
