Is what its saying
Hey Dulki,
I saw your name in the players list.
So did my advize help ?
Yea I think so I’ve been on all day without any problems =)
Good, problem solved !
If you do not mind could you please send the solution for this issue PM me. Faced the same. Off today $ 300 to geek - checked the entire computer , changed the thermal paste, cleaned the dust (which was not), sdelali some tests, installed Windows 10, the latest version of the software ---- and still happens turn off computer during (the start of the game, or after some time)…
Dang this is an old thread! 
Things I’d check:
Are any of your cores over-heating?
Are your fans working?
Do you have a lot of processes running/updating/searching in the background?
Do you have more than one anti-virus running?
Is your PSU sufficient?
Do you place your CPU in a small, enclosed space?
Did you give Boundless high priority in your processes?
One more thing: PSUs don’t last forever, and inexpensive ones last even less time. Any time you get weird problems like this, the first thing to check is the cable (80% of all problems are caused by bad or loose cables and cables are cheap), then try replacing the PSU.
Background - only the application Windows (just reinstalled today).
What’s your PSU wattage
power supply 550
Do you have an integrated graphics card?
You say you have a new install of Win10…has it fully completed all updates? Is defender on/updating?
nvidia geforce gtx 1060 3gb
8 GB of RAM
until recently, there was no such problem.
I will try to install all the currently existing updates for Windows. Once I do that and will report here if I faced with this problem again
I would also update all drivers - even for any new hardware
all drivers required to run the game are installed and have the latest updates
