Windows 7 Random CPU Spikes

So, I am I having a serious issue with my computer. This issue is random CPU spikes, I have an AMD FX 8150 with 16 GBs of DDR3 RAM and a fresh Windows 7 install. So my issue, I while using my computer I will get random CPU spikes that cause the PC to come to a halt My CPU usage will go from 10% to 100% and will stay at 100 for 30 second to a minute. This mostly happens when gaming but also happens when just browsing the web or being in a Google Plus hangout. I have done a mem test and there are no memory issue and am on the latest BIOS build. Any help would be great.
