Running slow in general or when performing specific tasks?
Did you check your Startup programs list? Perhaps you have some or several starting up.
Also check task manager and see which programs are taking most of your resources.

CPU seems a bit high temperature if you are just idling. I have a similar CPU, i7-4900MQ and with just Chrome and Speccy open it runs much colder.
