I am using HP Pavilion Desktop 570-p030

[U_K_4]

After a few attempts, my CPU has stopped booting. I tried to use my hard disk on a serviceable CPU but it failed to boot. I also tried to use a serviceable hard disk on my CPU but it also failed to boot. So my current problem is that my CPU is not able to boot.

Thank you
