I have a Gigabyte Z68A-D3-B3 and a i7 2600K Processor. Im currently having a problem with my cores. Its showing only two cores in my task manager. I've checked the bios and it say all cores are on and i check HT as well. I think it might be win 7, i didnt install a fresh copy of it when i switched from an amd processor. Please help me.
