The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

100% CPU Utilization in Win2000 & XP

Asked by Shanidar in Operating Systems Miscellaneous

Tags: utilization, cpu, svchost, xp

Good Day
I have read all the potential and tried the applicable ones before posting a question.

I have a HP Pavilion laptop.  The hard drive failed physically and was replaced.  First install was Windows XP-SP2.  It was very slow with 100% utilization of CPU, by svchost and/or System process.  Not believing that I had a real problem, I formatted out and installed Win2000 which I had run for two years before the hard drive issue.

I   ran the sysinternal process explorer an I am seeing more of the problem, but not enough to solve it.

Interrupts DPCs and System are all consuming ~33%  varies somewhat but the net result is 100 % utilization, making the machine very slow.  I am noticing on my work machine, that the Interrupts are not going much higher that 2%.  So I am fairly sure that one of the problems, is whatever is causing the (as high as ) 48% Interrupt count on this machine.

It has been virus scanned with a CA antivirus tool and scanned for adware with ad-aware

As part of the investigation, I needed to upgrade IE 5 to IE 6.  I downloaded and installed.  When I go Help> About, IE still says that it is IE 5, in the graphic portion of this window, but shows the version as 6.00??  I added this part, in case it sheds any light on this weirdness
