That's very, very vague... can you be more specific? Fill out your profile's system specs with processor, RAM, etc. - type in "dxdiag" in your start menu if you don't know what any of that is.
I've heard undervolting was locked out on some earlier generation Intel chips due to a vulnerability, might be affecting you.
hopefully this hasnt been locked out, here are the specs you asked for
