Hi,
This is my first time posting but have been lurking and reading for a number of years.

So, I have a new setup I built and it has been running great for a little over a month....UNTIL last night. I was playing Skyrim and it shutdown completely. CTD is common with Skyrim but I have never had full shutdown from it. It did not Restart and when I attempted to turn it back on, I got nothing. after talking to a friend, I remembered my board has a Power button so I tried that and it came back on just fine. I have shut it down and restarted with the case Power button since and it works fine. Not sure what happened last night.

MSI Z270 Gaming M7
MSI GTX 1080
i5 600k Skylake w/ Noctua dual 140mm, 6 pipe cooling it
Seasonic 1000w Gold - about 2 years old; only non-new part in case
4x 16Gb Corsair Dominators

My first thought was the cable that sends the signal to board to power up but it seems to be working fine after a few normal shut down/ start ups. Could it have been yet another problem Skyrim can have, a PSU issue or something else?

Thanks for any help,
J.

EDIT: At the time it was CPU was OCed from 3.8 to 4.5 using the MSI Command Center but I have since set it back to factory 3.8

It happened again today. I was playing Skyrim and just as I did something it shutdown. It then refused to turn back on until after I had turned off PSU at the switch for hour and a half or more. I used mobo PWR switch to turn it on since that's what worked last time; I probably should have tried case PWR first.

A little history; The PSU is actually 4 years old (I decided to look up order history(man, time flies) and has been mildly shaky in my previous build. We get powerful storms here in Spring and Summer and it's pretty common to get power blinks (whole house turns off and then on in less then a second). When this would happen, I would have to turn off PSU, wait a few minutes, turn on, then I could boot up normally. The PSU is the only part in my current build that is not new as it's a Seasonic that I thought was working well and had attributed the need for switching off and wait to the nature of a power blink. However, now the problem seems to have followed me to the new build and requiring a longer and longer wait before being able to power up system.

I don't have a meter to check it but am waiting on a friend to borrow his brother's. In the meantime; I bought a new PSU and am in process of RMAing my current one since it is under warranty still. I just hope that it is actually the PSU causing the problem.

Feedback and opinions are much appreciated
