For the last 2 or 3 days my CPU has been spiking to 100% for no apparent reason. It causes the entire computer to stutter (mouse/keyboard input, audio, video) for 5-10 seconds and behaves a lot like internet lag, giving a few frames or sounds while frozen. It happens at random times, it doesn't seem to matter what I'm doing (web browsing, gaming, even listening to music with the screen off). At the bottom of Task Manager it says CPU Usage: 100%, but when I look at the processes, their usage never adds up to more than 20% or so, even when playing a game. I have a pretty good rig overall but the processor is middle of the pack at best (AMD Athlon II X4 640, 3 Ghz)
I've already scanned with multiple antivirus programs and came up clean. If there are any logs I should upload just tell me, I don't do this a lot.
