A few weeks ago my original power supply, Corsair AX760i, started randomly getting stuck in power on/off loops. It would reboot, the fans would spin up then shut off after 1-2 seconds and repeat. It originally, first occurred when someone plugged a vacuum cleaner to an outlet in the room (not same outlet or surge protector though) but started occurring more without any seemingly reason. Leaving the system off for a few minutes / hours the system would boot. A lot of the times I would see a message about overclocking failed. Eventually, the computer wouldn't turn on, nor the fans would spin, the only thing the PSU would do is click on and click off. The Self-Test on the back of the PSU would neither show green or red too.
I contacted Corsair RMA dept and they replaced my PSU with an AX860i. Cool, I hoped this was the last of it.
Fast forward a week to today and the new PSU is starting to behave like the old. This time I kept the system off for a few minutes then turned it back on and the bios mentioned there was an overclock problem. I didn't boot to OS and turned the system off and hit the power breaker on the PSU until further analysis.
The system is less than 6 months old too. I have another computer in the room and its running fine. I bought a new surge protector too.
- What's going on?
- Is it something with the wall outlet? Is there any way to detect surges? The surge protector still says "Grounded"
- Or is it something in the machine?
- Is it something as simple as the overclocking failing? (why would that kill the old PSU?)
- How do I go about diagnosing the parts?

Additional Information
I installed the Corsair LINK for my AX860i PSU. Here is the info it returns
The Event Viewer didn't show anything overly suspicious. The Error is from the screenshot: "The previous system shutdown at 9:31:05 PM on 12/15/2015 was unexpected."
