Kernel_task greater than 100%.

I upgraded my memory to 16GB and now the fan runs constantly and the kernel_task is greater than 100%. The screen no longer works and I may have damaged the screen connector, so I am using an external monitor. Needless to say, my upgraded machine is much slower than when it was 8GB.
