Windows 7 Random CPU Spikes

[RadarGaming]

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.

When you did MemTest did you do it one stick at a time? I think they recommend atleast 8 passes.
