mm I need You to do 2 things.
1. remove the CPU heatsink, and remove the heat trnasfer material, and use alcohol to clear both the surface of the CPU and the heatsink.
USE some good heat transfer aterial, like AS5 (asc a computer shopkeeper for a heat transfer gel between the cpu and heatsink)
re-assembly the cooler, make verry sure its holding tight, and make sure the fan is connected.

2. go to BOIS screen, and search the tab that shows voltage readings from the PSU. Post them here.


The fan in the backside of Yours computer case need to blow air INSIDE, do check if it does. Or else it will only suck away air from CPU fan, wich is BAD BAD BAD IDEA.
(PSU fan blows air OUT of the box, thisone needs to PULL IN air.)
