    CPU Usage Suddenly Rising to 100%


    So I just had my PC turn off on me and as I waited a bit, turned it back on and started investigating, I found out CPU usage is jumping to 100% as soon as I open anything and CPU starts to heat up really quickly!

    Really clueless as to what could be causing this and a google search didn't yield fruitful results, so I'm hoping perhaps someone here had the same issue, was able to fix it and could lend me a hand.

    To clarify, memory and disk usage remain normal and only CPU usage and temperature are spiking up to the point that previously seamless activities are now stuttering as if my CPU power wasn't enough to run them.

    I'm using an AMD FX8350- 8core 4.01 and 16gb ram

    cpu usage at 100%

    CPU usage at 100% from start up for no apparently good reason. Service Host appears to be the problem but I cant narrow it down more than that at present.

    Any suggestions?

    I am using Windows 10 full release version 64 bit.
