Is this normal for a CPU?

[savvamadar]

I have an i5 3750k @3.4ghz, and it seems to be going crazy while IDLE. My whole PC seems to be lagging right now every 5-7 seconds it will freeze for a second.

Dunno how to add pics sorry,

SOLVED MY PROBLEM, it was a faulty driver, after disabling it my system runs amazingly and even my internet speed multiplied by 9. From 300 kb/s to 2.8 mb/s
