Hi, so I just installed a new cpu into my computer and I plug all the wires back in and there is no responce from the computer after pressing the start button. I have gone through multiple troubleshooting guides and my motherboard is not physcially damged or smelling, all the wires are back as they originally were,my power source is barely a year old, placing my old cpu in does not change anything. I have no idea why it is doing this. Please help
