Could not allocate memory: System out of memory!

Hey, all the time im doing something with particles on almost empty scenes with few cubes and plane I’m getting this error…
I have reinstalled Unity, cleared Unity cache manually and by unity settings, cleaned with CCleaner, Tried on different project, changed size of pagefile… Nothing helped.
Any suggestions? 78732-fatal-error-unity-allocate-memory.png

I’m having exactly the same error while working with Shuriken of basic particles.

I was changing parameters on my particles, and Unity used to crash randomly during any of these kind of manipulations…
I don’t know if it’s linked to my GC (Nvidia Quatro K1200) or if it’s the editor itself, as I’ve other people around me who’re using the same card.

Thanks !
