Trying to help my brother out but having no luck
So my brothers pc will turn on but after a couple of seconds it’ll start to beep, 5 times for around 18 seconds then turn off and restart and do the same thing. I have taken the 5v battery out and left it 5 minutes and nothing. I then took out the ram and tried one at a time and again nothing. So I have then taken the cpu out and refitted it and applied fresh thermal paste and nothing. I think it’s the cpu at fault as there was no thermal paste to clean when I took the cooler of so I think that the CPU is burnt out but just looking for a second option, thanks in advance
