    Im wondering if something in your BIOS got changed. Many times your BIOS will give you the option to downcore the processor and disable cores. If your able, go into your BIOS and check your menus having to do with hardware and performance. Look for anything having to do with processor cores and make sure all the cores are enabled.

    It only have 2 options either auto or single core. But when i try to switch on single task manager shows 1 core 1 logical. when on auto 1 core 2 logical. Or maybe this is a bug or something. What do you think is the problem

    Unfortunately its hard to say what could be causing this. Ive never had experience with an issue like this. Maybe someone who knows these kind of problems better will come along and give you better advice.
