Okay, so first of all..
My computer does crash from time to time when i'm working on projects in Studio One. I believe these are caused by my sound interface. Gonna replace that asap.

However, just now, while i was working on a song, the whole system froze, and i was expecting a black screen followed by the "Display driver stopped responding" message, since i get that from time to time.. but instead, it just froze up, and the screen got all these blue pixelated dots all over the screen.
Only on my main screen though, nothing on the monitor next to it.

Had to do a restart to make it work again.

Checked temperatures in SpeedFan, and everything seems fine..

Any ideas what might be causing this?
Thanks.
