I am trying to fix my mom's Dell Inspiron 530s and after everything I've read it is more than likely the CPU. My mom's desktop won't turn on. The green light turns on, but nothing else will. Before the computer started to act up, the computer was infected with the ransom virus. I reinstalled windows to try and rid of it, but I am not sure if the virus messed with other things. I was hoping I could use the CPU from my HP desktop, that I don't use anymore (But has trouble too, like it randomly rebooted and reinstalled windows on its own) just to make sure the CPU was the only problem. Could it be the ransom virus just caused havoc on the PC?
