I ran memtest and got no errors. - My GPU is a GTX 660 running at 81 degress when gaming, I now its high. But the freezes also happen when im just using google chrome and the GPU is under 55.

this is my SSD test: - it says ok, but is it really?
and SSD 1st https://gyazo.com/2ced670535888aa3d4294277e8d2040b 2nd https://gyazo.com/5d44dd87c8f52f6c3ecbfe1d6fb85195

- I strongly believe its the motherboard. But I dont know how I can tets it at this moment.

In event log I get event 41 kernel power, But cant seem to find a fix.
Anyone who can help?
