CPU usage at 60-100% all the time

I just upgraded my prebuilt with a new case, motherboard, power supply, gpu and new thermal paste but whenever i open or run simple programs my cpu usage goes to over 50% for that one program. Note:The processor is constantly running at its max clock and even towards its boost clock most the time.

Amd a12-9800 apu
Gigabyte AB350 D3H microatx motherboard
asus eah 5670
thermaltake 700w psu

  3. When you swapped out to your new motherboard, did you do a clean installation of Windows? If not, the old motherboard's chipset drivers are still embedded into the operating system and you will get conflicts.
