Windows 10 screen power off issue. - Microsoft Community

i bought custom built pc win 8 preinstalled in 2014.
upgraded win10 in 2016.

after upgrading win 10, experience odd problems.
after reboot or start up, seems work normal , monitors turns off after 15min.

due weather station software, uploads info web site, not allow pc herniate. have set 2 monitors power off after 15 min. worked every time when running win 8, , every time after startup or reboot win 10.
when using other programs monitors don’t turn off , have reboot å enable again.
have tried identify program causing this, , seems several programs or “tasks” causing this.
1 have identify sure, qbittorrent program (also other torrent clients), if have downloaded something. though have shut down after use.
other programs or #tasks” have not been able identify, because seems bit randomly!
have tried see if have running tasks or programs connected torrent client, have not been able figure out why happen.
1 thing sure, have same hardware , software when running win8. none issue.
can me , advise me or how can identify preventing “randomly” monitors switch off?
