"cpu is allways showing 60% to 100%"

Did you check Task Manager to see which program is hogging the CPU?

"two times formatting but nothing chaged"

That should mean that you completely erased the HDD & re-installed Windows from scratch, is that what you did?

Your tags indicate you have a laptop. Laptop settings default to throttle the CPU to conserve battery life. For this reason you may see the processor running at close to 100%. However, that figure is 100% of the current throttled processor speed.

Where are you seeing those numbers anyway? If viewing task manager you should see system idle at near 100% at least some of the time.

Your laptop may have default settings to run the CPU at full speed when connected to the AC house current.

If your CPU usage is high at times, then you may disable Indexing on system drive and the other drives/partitions and observe if there is any improvement.

For this, open Computer and right-click system drive and click Properties. Uncheck the two checkboxes on the bottom of the window that opens. Do the same for all drives/partitions.

If your system becomes as responsive as you like it to be, then you may use your computer this way. You may search over the internet about what the things you have unchecked do.

deyprasun59, a thought; possible your index.dat file has grown too large? A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner (free @: http://www.ccleaner.com/) can get rid of it when it’s ticked (not to worry, it gets rebuilt EMPTY on the next boot.). May not be your deal at all, but won’t cause any harm to try. I run it often. Can't recall if it shows up on the activity list or not?
