Unstable installation

Hello
I installed a SW 2015 on a laptop, and I sometimes have crashes without any warning. I would like to find the weak point to try to remedy it.
My config is as follows:
250 GB SSD
Intel I5 6200, 2.4gHz
No dedicated graphics card
8 GB RAM + 16 GB virtual on the SSD
Windows 10
SW 2015

I know that this configuration is not recommended by Dassault Systèmes, but that for small sets it must pass.

When a crash occurs, I don't get a memory usage alert message.
No worrying things either at the level of the resource monitor.  On a task a little heavier than the others, the processor of course regularly goes up to the cleat, but the work is done at a pace that suits me, and then suddenly "Poof", nothing. Back to the office...

Wouldn't there be something to see on the riders' side?
How do I make a diagnosis?
Thank you

Hello

2 big black spots on your config:
- Graphics card: source of errors and 3D calculation, moreover, I think your video card must share your 8GB of RAM
- RAM, 8 GB is low with a Win10, even with 16 GB virtual.
Crashes without a message, are often related to memory stack errors (CPU level) and created in full crash.
Fortunately you have Win 10 otherwise it would surely end up in system crashes.

The fact that the monitor doesn't indicate memory saturation, does it fit with the hypothesis of insufficient ram?

on occasion I will put 16GB

Thank you
