As you can see from the title my issue is that there are some PC at my workplace which restarts randomly.
It is very sporadic, as sometimes it runs for 3 days without errors and sometimes it restarts more than twice a day.
What I could figure out so far:
Every restart case leaves the following messages in the event logs:
Critical:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
Information:
ACPI thermal zone ACPI\ThermalZone\TZ00 has been enumerated.
_PSV = 0K
_TC1 = 0
_TC2 = 0
_TSP = 0ms
_AC0 = 353K
_AC1 = 328K

_AC3 = 273K
_AC4 = 273K
_AC5 = 0K

_CRT = 378K
_HOT = 0K
_PSL - see event data.

It's the same message every time. I read the article from windows which describes what these meaning:
https://msdn.microsoft.com/en-us/library/windows/hardware/dn757331(v=vs.85).aspx
But from this, all I know that somethings overheating for some reason, and it exceeds the limits described in the above information messages.
Based on these messages, I though that the CPU is the bad guy in this case, so I've dowloaded the Core Temp application, which is able to log the temperatures into a *.csv file, as I though I could catch it in the act.
But no, there was a crash at the weekend, and all I saw, that the logging stopped just 10 minutes before the event log says the machine crashed. The temperatures was good, (around 30°), yet it still restarted.
There is noone else who would touch these machines, and there was no power outage, so these could not be the case.
Also tried to turn off in the Startup and Recovery, the automatic restart of the computer in the event of an error, and set to create a DMP file.
As it is possibly a hardware issue, I think there will be no DMP files. Especially if it overheats, because it will restart instantly to prevent further damages.
So following the idea that somethings overheats, I've downloaded the PRIME95 and did a 10 minutes stress test for the CPU and then for the ram.
The CPU was running around 85° degrees, but there was no crash and now slowness. Did not wanted to push it more, as the CPU manifacturer says that 72.72 degrees is the maximum and above this degree the CPU will degrade.
The following messages appeared before the crash:
The Application Experience service entered the stopped state.
The Application Experience service entered the running state.
The operating system started at system time 2015-06-15T02:20:52.109999300Z.
File System Filter 'FileInfo' (6.1, 2009-07-14T01:34:25.000000000Z) has successfully loaded and registered with Filter Manager.
The previous system shutdown at 4:20:00 AM on 6/15/2015 was unexpected.
----
Also I've checked the fan manually, and it seems to be working fine, and there is no sign of a single dust inside the PC.
I have run out of ideas, as I could not reproduce the crash.
Can any of you experts give me some ideas what could be the issue?
