Windows 10 randomly shutting itself down

[Bruce]

sounds like the PC shop may not have either been up to the task, or had a pretty crap care factor.
a good one would have replaced the PSU and tested your rig.
then replaced the mobo and, again, tested it.
then memory and more tests.

they could have easily replaced the probable hardware until the PC stopped shutting down.
sounds like you are getting the shutdowns regularly enough that a few days at the repair shop would have been all that was needed to see if they were on the right track.

as to the 550watt PSU, yeah, although physically it would do the job, it would be on the low end of minimum requirements. and with the current PSU being one of the suspected offenders, I don’t think you want to take a step backwards on that front. especially trying to factor in upgrades down the track, one of those would most likely be an even bigger graphics card, requiring more grunt and straining further the 550watt PSU.

Update:

I ran a whole bunch of tests, and i have come across something interesting

While messing with the wiring in the case, i noticed that i could get the PC to turn on, and off, while messing with the cables that transfer power between the motherboard and the LEDs, USB and Audio ports, and the Power button.

I kept moving them around until i found a “sweet-spot” and then fixed it with electrical tape. I can’t tell if the problem is in the Motherboard, the wiring, or the frontal panel.

I have been using the PC with no shut downs for the past two days. The longest yet, though i feel like i need more time to know if it really stopped or just took a long break, since the problem is random and this could be pure coincidence.

The BSODs that remained seem to have been a problem with DOCP. I solved this by changing memory frequency to 2933MHz from 3000MHz, setting the timings manually, setting the voltage to 1.35V manually and changing the “tRC” latency from 58 to 60. A lot of people that were having this problem with the same memory as mine solved it this way. Seems to have worked for me as well.

Since the CPU was also misbehaving, and that suddenly stopped, i think it might be something with the Motherboard itself, but i could be wrong, so i will test and stress it a little bit more so i can be sure i need a replacemente, and not just a new case.

sounds promising… fingers crossed.(y)

Well, i guess this is to be the last update on this saga.

After some more careful testing, i got no more shutdowns or instability. It was indeed the cable that connects the motherboard to the power button.

I did not need to replace anything, i simply bought some specialized product for cleaning electrical contacts and applied that to either end.

As of my last reply 7 days ago, i have not had any more problems. I also added some electrical tape on top of it to fix it to this “working” condition.

My full gratitude and thanks for the help, it was much appreciated, @Bruce

no sweat, glad to help.
and good investigative skills to you!
good to hear it turned out simple enough.
