Computer shuts off randomly without warning

[Michael0728]

 Randomly the computer shuts off without warning. I haven't exactly narrowed it down to why it happens or what is causing it. It may or may not be just when it's getting a lot of traffic, because I suppose it happens mostly when I'm gaming. However, I do know there was a time I was only attempting to burn a cd, and it did it as well. No programs running in the background what so ever.

I know a fair amount about computers, and so I know the typical number one problem is usually the PSU. Well, I upgraded that from a 550w, to a 1000w supply. Still happens. I custom built the PC myself, two years ago. It only started doing this, roughly 6+ months ago.

OS: Windows 10 Pro 64-bit
Processor: AMD A10-6800K APU w/ Radeon HD graphics (4 CPUS) ~4.1GHz
Memory: 8gb RAM
Hard Drive: 1.8 TB
SSD: 111 GB
Display: NVIDIA GeForce GTZ 960 5698 MB

Check your temperatures...

[Michael0728]

How do I go about doing that? A program?

And would temperature be an issue after a year a half or so, then randomly start?

EDIT: I did get a new computer desk, which means a new location on the desk for the PC itself, but for the life of me I can't remember if the time frame of when I got the new desk and when the issue started add up.

Try SpeedFan...Free

[Michael0728]

I'm not sure what I'm looking at here. What's good or bad or what's what.

Currently I have nothing extra running besides this browser and Speedfan, and this is what I get.

Fan1: 1945 RPM          GPU: 28C
Fan2: 0 RPM                Temp1:28C
Fan 3: 0 RPM               Temp2: -8C
Fan 4: 0 RPM               Temp3: 17C
Fan 5: 0 RPM               HD0: 24C
                                    HD1: 25C
                                    Core: 6C

Looks good...may not be temps...
However check it under load...IE: gaming whatnot....

[Michael0728]

Alright. I'll try to give that a go as soon as I can. Thank you for the quick replies thus far.

EDIT: So I hooked up my dual monitor, to record the second screen with SpeenFan running on it's display, to record while I run some manner of game on the first display.

Just Three Mintues into the game, fullscreen on display 1, the temps read as follows:

Fan1: 3245 RPM          GPU: 44C
Fan2: 0 RPM                Temp1:30C
Fan 3: 0 RPM               Temp2: -8C
Fan 4: 0 RPM               Temp3: 68C
Fan 5: 0 RPM               HD0: 25C
                                    HD1: 25C
                                    Core: 53C

Anytime...you can also DLoad burn and run MemTest...also free... and let it run when you aren't usin the PC...like tonite.
That will eliminate bad RAM as the culprit as well...let it run at least 1 hour.
Any errors at all = bad RAM.

I too think this is concerning temperatures. From the similar problems i have had, It leads me to suggest that you should check the cpu gel that goes in between the cpu and the heatsink. Then look for issues with your graphics card. It could be that as well. These were the two issues i have had with my desktop over the years when it comes to 'turning off all of a sudden'.

Also, check the fan inside the power supply. And measure power supply temperatures with a real thermometer.
A power supply will shut down when the temperature inside it goes over a certain limit.

I'm 100% sure it isn't the PSU. As stated I bought a brand new one, and it literally shut down again the same day. I ran the Ram test for almost 24 hours, and have 0 errors.

As far as the cpu gel goes, I'm afraid I have no clue on that. I did check into my graphics card though, because this beast has two fans on it, that I never see on, however according to what research I did, this is intentional, as they only come on when cooling is needed. The other two fans I have in the case itself, work just fine.

EDIT: As my computer has been on consecutively for the last 24 hours, while running to MemTests and the SpeedFan, I notice this.. my CPU usage is at roughly 77%-82%. (I'm running no other programs at the time of these readings besides the browser and SpeedFan.

Fan1: 3214 RPM.
Fan 2-5: 0 RPM

GPU: 26C
Temp1: 32C
Temp2: -8C
Temp3: 84C (Fire symbol next to it.)
HD0: 24C
HD1: 25C
Core: 71C (Fire symbol next to it.)

The rest indicate a blue arrow pointing down symbol.

That core temp is too high for just a browser and speedFan running...i would re-do the thermal paste and/or check to see your cooler is mounted properly...
