Windows 10: Random Shutdown, build PC, Win. 8, Win. 8.1, & Win. 10

Not sure why my desktop does this, I am running a 1000W power supply, I have (4) 3TB drives in a hardware RAID 5 configuration, a 120GB OCZ Agility 3 SSD, and a Western Digital 1TB Black hard drive. I am maxed out on RAM at 16GB, and running a Phenom 955 BE on a GA-990FXA-UD3 board with BIOS updated to F3.

Log details below, I don't know how to decipher.

Device and performance & health

• When I bought it in May 2013 it was win. 8, then win. 8.1, on to win.10 version 1511, then win. 10 version 1607 (anniversary edition) & 4 days ago to win. 10 version 1703 (creators edition.
• HP
• When I bought it I had Norton.
• I don't think I did.
• Win. 10 version, 1703, OS build 15063.138

 

This is nothing more than an semi-educated guess.
According to the logs you had an "unexpected" system shutdown. This could indicate that it was a hardware-based issue. If you are overclocking your system or the memory, try dialing it back.
