Hey General, i understand your frustrated. But we don't sit here on our time waiting for someone to get a attitude with us. Now to check your BIOS restart your computer, and once the computer comes back up there will be a Bios Logo screen (Manufacture name and Board name) press the Key it says press on the screen. Now idk what board you have but make your way over to the CPU tab and key down to Number of cores List. You should see core 0 and Core 1. Core 0 Will always be enabled because obviously if you turn the 0 core off then your screwed. But anyways if you see a core 0 and a core 1 then you have two cores not 1. Your CPU is a quad core. So either the cores are now busted or they have been disabled in the bios and you have to re-enable them
