Are you expecting something to be running on the other cores?
If you don't have more work than can run on 1 cpu, the other cpus will not do any work.
How are you measuring your cpu usage?

>>>The problem is when i monitor my cpu performance i saw that core 1 usage is always 100 % and the rest core are between 0 and % i have updated all my drivers and still having this problem :( any ideas?>>>
You can download Xperf toolkit from Win SDK and perform so simple analysis of the CPU load.Run xperf.exe -on -stackwalk +easydiag.Save the file by entering this command xperf.exe -stop -d "your trace name.etl" and opent it with GUI version of xperf.You should get nice graphical breakdown by thread and core of CPU load.

Looking at the sidebar I noticed that core 0 was running between 93 and 100%. I had no applications running. Now this is absolutely not normal. Normally while in vista or on the net my cores run between 0 and 4% and for jocuri fotbal and perhaps will be fine.

Can you check your CPU load with the Process Explorer?Posting of the results will be appreciated.
