How can system mechanic tell me my computer has numerous issues when the computer is brand new?

I have had experience with system mechanic on my old dell computer and I thought it was a good program, it helped me fix a lot of issues with my computer. I recently bought a new Lenovo computer and I installed system mechanic right away. On the first scan about 8 different problems came up and it said my computer is in bad shape. How can this be? I don't understand how a brand new Lenovo computer can have so many problems on the first use. Is system mechanic just a scam? Does the program itself upon installation cause my computer to have these problems, creating the illusion that my computer is in bad shape so that I feel that I need system mechanic to keep my computer alive so that I keep buying it year after year? I wouldn't be surprised. I'm just speculating here, if anyone has some real information or advice I'd love to hear it.
