Computer shuts down in 5 minutes w/o warning (dxdiag included)

[NuVioN]

My father's new computer shuts down in 1-5 minutes w/o warning and we can't find a solution as to what is causing it. We did the memory leak check and its oke, malware bytes scan found nothing and computer temperatures are around 32, never above 40 when it shuts down. (the computer is running win10)
It has 1 fan, runing at 2260RPM.
Maybe its important, I put the desktop and program files to E: partition because windows is installed on a SSD and there is only 50 more GB left there. (My father has a tendency to put everything on the desktop). I did that 2 months ago and everything worked fine till now
Here is the dxdiag http://www.filedropper.com/dxdiag_16

Update 1#: It now just restarts out of nowhere, it doesn't shut down completely.

Sounds like a bad or failing PSU. Usually temps or PSU will cause reboots or power offs without warning as you describe. What make/model is it?

I went to the event viewer and found that it has all the logs when it shut down /restarted. It says critical event, with source Kernel-Power

1. Event ID - 41 only signifies that "I shut down and I do not know why"
It does not really explain anything.

2. That PSU sounds pretty shaky.

3. What was the last thing you did before this started happening?

4. What are the rest of the specs of this PC?

3. Literaly nothing. in some cases it was scanning, in some cases it was idle on desktop, in some cases chrome was turned on.

4. MB ASROCK H110M-HDV
Intel pentium G4400 3.30Mhz
Corsair 4gb DDR4,
HDD Seagate 1TB 7200 64mb SATAIII
SSD Kingston UV400 120GB,
LG DVDRW 24X
TP-LINK TL-WN725N
Inter(R) HD Graphics 510

Checking the event log this happened every week once and then last 2 weeks when it happened it happened throught the day as the computer was used. Around 40 Id41 errors, 10 of them today

Very likely the PSU given the info provided.

 

[USAFRet]

Swap in another PSU.
