what's wrong with my cpu usage?

[Ashleyyyy]

every once in a while i get random 100% usage on one of the threads of my cpu. i don't know what it is.

Usually something is working and using that thread. Could be a program reaching out to check for updates etc..

it doesn't show anything in the processes tab that looks unusual... and if it's a program checking for updates that would be weird because it happens every 5 minutes or so...

the X5650 has a terribe single core performance especially at that clock speed so it's not out of the ordinary that a normal program would peg 1 core to 100%.

 

and you should be able to see the program that's using your CPU in the processes tab, and remember the processes tab will tell you the overall CPU usage, so one program using around 4% of the total CPU usage, means its using 100% of 1 core. (since you have dual xeons)

 

and it's not always the case to see one program using 4% of total CPU usage and expect to see 1 core pegged, some programs spread that usage on multiple cores.

yeah programs like chrome do this. if you look at the screenshot the core's that have about 10% activity on them are because i had a youtube video running when i made that screenshot.
