Hello and thanks in advance for reading this.
All specs posted at end of the post.
I recently purchased a new CPU to replace my old, overheating CPU. After installing the new CPU and turning the desktop on, I immediately noticed that the CPU heat sink fan and chassis fan start up for a second, stop for a second and then start up again. After the second “restart” all computer parts sound like they are running fine. There is no display to the monitor with this new CPU. I double checked the monitor connection to the desktop and the video card to the mobo.
I reinstalled my old CPU and there WAS display on the monitor. I am assuming that it is the new CPU that is causing the problem. Upon further inspection, it was noticed that with the OLD CPU, the chassis fan spun much faster than with the NEW CPU. With the new CPU, even on the high setting, the chassis fan is spinning much slower. With this, I am assuming that the NEW CPU is not running because of the PSU.
Any thoughts? Again thanks in advance.
