HI ,,
I have compaq presario CQ42 laptop, and from last few days its show 100% CPU usage and its freezes all the time. i have unintalled and reinstalled the operating system ( windows 7 Ultimate ). Tried to use without charging the laptop still its shows 100 % usage. i checked in task manager and i do not see any third pary software running in the background. And also processor fan runs fast and gets lots of noise and gets over heat.
Need help to resolve this issue. i am not able to use my laptop only.
Please reply me with the solution to resolve the issue
