My build is

- Asus Sabertooth Z77 Motherboard
- Intel i5-3570K
- Cooler Master Hyper 212 Evo (Previously Corsair H100i)
- Evga Nvidia Gtx 680 4gb
- SeaSonic Platinum-1000 1000W Psu 80 Plus Platinum
- WD Black 1tb
- Samsung 850 Evo 120gb
- 3 other drives I should probably wipe and remove

I come home from vacation the 9th of June to find my power supply fails to start. I rma that and it takes 3ish weeks for Seasonic to get back to me with a replacement. I started off in a Cooler Master Haf x case, to a NZXT s340. I think the case was shorting the board, so I returned that and have it in a NZXT h440. Between the s340 and the h440 I had my computer set up on the motherboard box, cpu, gpu, ssd, ram, with it running 3 hours straight with no hiccups.

Maybe a week ago msi afterburner was reporting unstable fluctuating temperatures of my cpu 40-60° C and so I thought my h100i was going bad. I replaced it with my intel stock cooler nothing. Replaced it with a Hyper 212 nothing. I pointed an ir temperature gun at my cpu reporting 35ish degrees idle or under that instead. I think the motherboard is the problem here I think. I'm thinking I should rma it.

Some days it would run without a hiccup. Today it shut off on me twice and after that nothing. It successfully rebooted after each shut off though.

I'm going to be shipping this to cali in a day or two. Hopefully I can fix it myself instead of sending it to some computer place, but I might just have to. I wish I had the money just to rebuild an entire new system that would be smaller, faster, and run more effecient. Thank you all in advance for your help! :)

Also it seems my computer would shut off on me once or twice before it would be stable and not turn off for the rest of the day. Until I turn it off myself.

You forgot to include the ram kit in your build/systems specs. Please pass that along inclusive of your OS. When breadboarded does the issue come up? There was some known issues with the AIO you've mentioned where the backplate and the full tightening of the screws made too much pressure on the CPU socket to prevent it from working optimally. On that note is your platform's BIOS up to date? What TIM did you sue between the cooler installations?

I would also ask you to have an electrician look at the wall out;let and the houses wiring to see if you have any grounding issue.
