I'm getting ~20% CPU usage and core temps ~50C with 2 browser windows open (one streaming video and the other not doing much, only a few tabs).

Here are my basic specs:

Win7 pro x64

i5-2500K stock clocks

M4 ssd

gtx 560 gpu

asrock z77e-itx board

8gb ram

The system typically idles around 40C, I'm not sure what's going on here. No other apps running aside from firefox atm. Thanks

which process causes the CPU usage?

which process causes the CPU usage?

Please let me know how I can check.

run Taskmgr.

run Taskmgr.

Thanks, I had looked there, but wasn't sure what figure to check. I assumed it would be in the processes tab under CPU (as a percent maybe), but idle processes show 99 so my assumption is obviously incorrect.

Can someone please advise? Thanks

if nothings shows up, why do you think you have high CPU usage?

The CPU usage in Taskmgr as described in my first post. To clarify post #5, I am not sure how to determine which process is causing the high cpu usage.

Run ProcessExplorer as admin and look which process causes a high cpu usgae.
