System restarting on its own.

So i did some upgrades to my Pc . i had a :
CPU: I5 4670K .
GPU: GTX 780 .
RAM: 8GB (DDR3 1600).
Mobo: Gigabyte GA-Z87-HD3.
PSU: Cooler Master B700 700W

Now few days ago i got a new case..SSD. 8gb more RAM, new cpu cooler (Cryorig H7 ) and a GTX 1080.

everything runs great , but every now and than system restarts itself for no reason. it has happened like 3-4 times over the last 3 days since i upgraded. first i overclocked to 4.2 GHz but i set things back to default and it still restarted as i said.
My guess is mybe its the new cooler cuz i droped it once while mounting it, also put bit more paste than i shoul have but it didnt spill over or ....

i also ran the intel burn test and it said that its stable.

You don't need a product key to install windows 10

True that well i installed the new one .... let the pc running and left home and it seems it has restarted but not sure if its normal or not... i guess i have to keep using the pc and see it happens again
