Sudden system shutdown/restart, what could be causing it?

[Steevo]

NO blue-screen when it crashes, just a complete shutdown indicates a hardware failure that is unrecoverable. I would suggest booting and running a live OS from DVD or USB while you do some hardware testing to prevent corruption of the OS and any files.


Procedure is the same for either live OS or for standard.

Remove every stick of RAM except one, unplug any hard drives not used, open case and point a fan into the case to make sure everything is staying cool and start running mem test and OCCT.

It looks like the CPU is getting too hot, so with the case open and a fan blowing in see if it restarts.

hey! i'm experiencing simillar problem with my 7700k / asrock z270 pro4 / pretty old PSU - did you found solution for your case? was it psu?

Your power supply is questionable. Green is made by High Power, the consumer arm of the original manufacturer, which is Sirtec. These are not high end or reputable PSUs, they are used by Thermaltake and others for their low budget power supplies. 4 sticks of RAM draw more power and so do hard drives. Try removing 2 sticks and any unnecessary hard drives and lighting, and test again. If the problem goes away, buy yourself a better PSU. http://www.realhardtechx.com/index_archivos/PSUReviewDatabase.html

Ok first of all this is an old thread, so read this.

Second replace your powersupply.

Make sure "automatically restart on system failure" is disabled. By default, Windows hides BSODs via restart.

1. Big necro on the thread so the Ops {PSU is different from the new guy so the advice is for a guys who's not been back in long toime...

2. For the new guy ... when ya system crashed, you should see a stop errors code ... copy the 0x00000124 or whatever number and search web for answers. If ya don't see it, turn off autpo restart.

3. Alternately, open Event Viewer and look at the Windows System and Applciation logs ... scroll down the lost looking for STOP or WARNING messages..... copy paste the description into a search bar and get ya answer.

Change your psu

Change your psu

unfortunately, changing psu didnt help. brand new CM 650W and still hard resets.
Windows event viewer says critical error - Kernel-power code 41, system restart due to critical error or unexpected power loss.
System at stock, no OC. Memory perfectly stable (12h memtest pass). Temps fine, all protections and power limits in bios off/on - no luck here too.
This only happens in p95 with AVX ON, and, surprisingly, while watching 4k videos on youtube.
Non AVX version of prime = perfectly stable.
If i downclock my cpu all the way down to 4.0 ghz or set avx offset at 5 - im fine. but even at 4.2 ghz there is shutdowns again. I just cant believe cpu can fail at 4.2.
Soo my only thought here - if it only happens under heavy avx load (but youtube crashes kinda confuses me) - then probably reason is failing motherboard. Can't RMA it, unfortunately

For me it was the motherboard. I bought a new one (Z97 pro gamer) and thanks to dear God I have not had any issues ever since.
There are several tests and good suggestions on these two pages, make sure to have a look at them and see which one is your case.

The OP's PSU is made by Hunt-key and not High point...
They aren't the best but they are reliable.
I found that by it's 80+ certs.
Then on the link provided by someone else Green is listed as being made by Hunt-key.

Some lower end Green models are made by High point but not this one.
