    I5-6400 only using 1 core

    by mrxlfred ·


    Hello everyone! I’m not sure if anyone has actually encountered this before. But, here’s the thing. I’m currently using I5-6400 (i’m only specifying this part because this is probably the only important one) which is supposed to have 4 cores. However, ever since this desktop was repaired. It has only been using 1 core. When this was broken, a lot of its parts were replaced, namely: PSU, Mobo, RAM, and HDD. The HDD was used is an HDD from an old AIO that we had here lying around. In the BIOS, it does allow me to modify it up to 4 cores, however, when I do, it doesn’t boot up. It just freezes. I’ve tried a lot of things. But none of them have worked. Has anyone ever encountered this problem? Thanks!

      Try to update or reset the BIOS.
      Also, check if it can be replaced under warranty.

      Really sounds as if the M’Board

      Is not compatible with that CPU you’ll need to check the M’Board Makers List of Compatible CPU’s to see what if anything needs changing but a BIOS Update may cure it but if you have never done a BIOS Update previously I must warn you messing things up and turning the M’Board into a Useless Paperweight is very easy so if in doubt don’t touch.
