Blender Restarting computer?

[Vypa]

Specs:

i7 4770k @4.2Ghz

gtx 780

8gb 1600mhz

(I have done stress tests, everything is working perfectly)

 

So when In blender, and I'm rendering something over 1500 samples my computer restarts, it used to be fine but now it's just gone weird.

 

What I've tried:

Reinstalling Blender

Restarting computer

Reinstalling Graphics drivers

 

It's not a big deal as I dont always render over 1500 samples, it's just weird that it's restarting.

 

-Thanks

What are the temps while its rendering?

Are you running in experimental instead of supported?

Have you tried running without your overclock? Could be instability.

Are you updated to the latest version?

Are you rendering with CPU or GPU?

It sounds like a memory error to me, try running a memory checker.

Im not to sure, last time I checked 100% load around 40-50 degrees C

I will try some of these, thanks for the suggestions!
