Does Cheat Engine effect your computer at all?

Yes and no. If you set some of the options such as Kernel Mode and Stealth Mode, then it does change a value or adds something to the registry the same way that any other kernel debugger would. So to begin with, Cheat Engine *does not* change your computer at all, but if you *want* it to, you can. its safe cuz its popcorn kernel lol stpid
