Hi

So I have buildt my pc 2 months ago without the gpu becouse I was waiting for the gtx 1060 to release. After building the pc I used my old gtx 550ti and I had no isuess with the pc. 3 days ago I got my new GPU (MSI GAMING X GTX 1060), I had no issues with it for about 1 day of use, but the second day I was on steam just borwseing not doing any heavy tasks, and my PC crashes to grey screen, I could move the mousecourser but I couldn't get out of the gray screen, the only way was to restart the PC by holding the start button down. After 4 hours same thing happened again when I was browsing on steam, PC crashes to grey screen.
Now have been using the PC for a hole day and it didn't happen again.

My question is: why did my PC crash to grey screen? is it becouse of my GPU? should I send the GPU back?
My PC is clean from dust, and the temps are rarely above 30 degrees.
