Help with newly built system (possibly overheating)

[BenBen90]

So this new build constantly reboots for a reason I am not fully aware of. It reboots on none stressing activities such as browsing the web or opening an application.

Specs:
FX-6300 cpu
Sapphire R9 290 tri x graphics card
m5a78l usb 3.0 motherboard
Ballitix ram 4x2gb
Corsair CX750 psu
Western digital 1tb

Also I am not here to discuss over the fact that my r9 290 can be bottlenecked by the fx6300, the r9 290 is only there temporarily. Please help me!

If it's possibly overheating you can give me the CPU temps

The temps right now seem to be all over the place but it is around 30 right now. Though it goes down and up from 25 to 45.

Edit: It just rebooted again right after I typed the above.
