Okay my brother built a pc. He used my old processor which is the i5 6402p and a MSI Bazooka motherboard and some fairly new Adata ram I had leftover. He bought a 1660 GPU and a new power supply and a Seagate Barracuda HDD. He turns it on and it boots to the bios and he can leave it sitting there and it will just shut off. He can also put in a Windows media flash drive he made from his laptop and it will install windows until about 30 percent and then it shuts off. He has reseated RAM and made sure all the PSU cables are all the way in, and tried different SATA ports and it's always the same. Any suggestions?
Update: He has four sticks of 4GB RAM and he took out the two older sticks and it can make it into the windows installation and it gets to about 40 percent before cutting off. With the two older sticks in it cuts off in seconds after it boots to bios.
Update 2: He checked his temperatures and his CPU is at 100 degrees Celsius right before it cuts off. Gonna redo his thermal paste and see if that helps. He has good airflow and 5 case fans. Cable management isn't to bad.
