Help-core 1 staying at 100% usage?

With all programs closed, just with sidebar open it says my core 1 is at 100% usage and that core two bounces between 2-5 % is there anything that may cause this?

This is on a fe855 with t5500.

Thanks!

 

It seems to me like ur familiar with task manager, since you got the cpu usage. Why dont u look 1 tab over at the processes and see which process is eating up ur cpu cycles.

 

It's possible that the spikes are from something like the indexing service, or maybe some sort of auto-update program. A lot of stuff is not written for multi-core/multi-CPU usage, which is why it seems like only one core is doing a lot of work.

 

Im very familiar with vista and xp. I checked that.

That is what is so weird. The max process usage with everything closed was 4. There were maybe 3 processes using CPU during all of this with the max being 4 and the others being 2. There may have been intermittent processes using maybe 1 or so but nothing that was constantly taxing the CPU.

I restarted and the core usage went back to normal staying <10% unless im doing something, but that sure was weird.


to respond to the post above. It wasnt just spiking to 100% on the task manager it was literally a straight line at 100% for core 1. I have never seen that before.

 

Did you click the button marked "Show processes from all users". If not you would not see all the processes running.

Yeah like scuderia and I said, by looking in the processes tab, you can see exactly which is taking the cpu cycles.

If ur cpu is at 100%, then the processes tab will show which process(es) are taking it up. W/o that, there is nothing but speculation we can give u as to the culprit. So if you want to avoid this in the long term (if it does indeed come back) then you need to identify what's taking up ur cpu cycles and tellin us here so we can help diagnose the problem.

 

this has been happening to me as well...it's pretty annoying, every time it happens my only solution is to restart the computer...
