Possibly a bad motherboard. This happened to my 2008 MacBook in 2015. Most likely caused by a faulty battery that expanded and pressed against the hardware for several years before I realized I should remove it. I had to get a new computer when my computer eventually refused to boot up, but the hard drive was fine, so I was able to transfer all of my files and didn’t lose anything.

Most likely caused by a faulty battery that expanded and pressed against the hardware for several years before I realized I should remove it. I had to get a new computer when that MB refused to boot up, but the hard drive was still fine, so I was able to get all of my files transferred over and didn’t lose anything.
