bsod when rendering 3d scenes for long times

[choochee]

hello all, new here, hope you can help me guys.
I'm using my computer to render for long hours-sometimes a few days.
Everything was going good until my computer started crashing after a few hours of rendering (usually happens at night as this is the time I leave it rendering).
So from about a week or so I can't use it for long time rendering. during work it's ok.
rendering is done by Maxwell render which is quite "heavy" on resources.
PC is i7 with 16GB ram.
thanks all !!! it really drives me crazy.

Reinstall Windows and make sure to update completely (excl. Windows 10 update).

You are running an Lenovo Product ID (PID) on a Gigabyte board.
This makes your installation counterfeit.
Troubleshooting a counterfeit installation is useless as it is not known what has been modified to your system.
A counterfeit installation contains heavily modified code which causes the system to behave in unexpected ways.
For this reason, analyzing counterfeit systems is unreliable and most analysts won't try it.
