Jesus, your board is about to blow.
1.49 vcore is too much for that 4+1 phase motherboard.
Turn back everything to stock. Your board is shutting down the pc to protect itself from overheating.
I estimate anything above 1.42 vcore is dangerous for that board without mosfet heatsinks.

Might be something that overheats

the heatsink does feel hot but not burning your hand hot. that's the only part with any real warmth to it really, the pc case has some awesome air flow antec 900 i think it is.

would a new psu solve this? is it causing the voltage problem?

or is it the actual MB?

I have no idea how to change the voltage or anything so not sure how to go about testing it

BTW i really appreciate everyones help so far

Change the voltage in your BIOS. Turn it down a couple notches to 1.40 or so. It's located in the same place you find all your cpu info.

As a matter of fact, setting it all to default might not be a bad idea.

its not the cpu thats hot but the vrm parts of the motherboard.

these small black squares are mosfets and probably overheating


Mosfets covered with a heatsink



Set everything in the bios back to default / stock settings, then read this

Can you try this.

Go into your bios (when your system is booting rapidly press the Delete key), go to MB Intelligent Tweaker (M.I.T.). Change Core Performance Boost to Disabled. Now go back to the main screen, then go to Advanced BIOS Features. Change Load Line Control to Regular or Normal. Press F10 to save the settings.
