100％的CPU使用率 [英] 100% cpu usage

问题描述

大家好。

我遇到了一个我似乎无法弄清楚的问题。我有WinXP Pro Service Pack 2.我已经安装了SP3的大部分更新，但不想要所有更新，所以我将它们定制为自定义更新。
我可以上线和浏览所有我想要的东西，但是一旦我登录到一个安全的网站，如Yahoo!邮件，或在线银行帐户，或任何需要用户名和密码的地方，我的CPU高达100％。我输入我的用户名和密码，然后它出现峰值。它将在那里停留大约4-5分钟，然后它会安定下来并登录我的安全网站。
我已经下载了进程资源管理器，但我无法弄明白。我不确定如何阅读线程或知道这是否是我需要查看的内容。我查看了Sysinternals Process Utilities，看看是否有什么可以帮助我，但我不确定哪一个最好，如果有的话。我真正需要的是列出每个正在运行的服务，DLL和其他任何可以帮助我找到我尝试登录时正在运行的内容的东西。我试图阻止所有不必运行Windows和Internet的服务，但仍然无法找到问题。问题出在服务上。我已经卸载了我可以在我的系统上找到的任何病毒防护程序，无论新旧，但仍然没有解决问题。
非常感谢任何帮助。

谢谢，
Teresa

您好Teresa，

这是奇怪的是，Process Explorer没有显示你的CPU周期花费在哪里。您可以尝试使用名为xperf的更强大的工具，该工具作为WPT工具包的一部分提供，可在此站点上下载。您需要捕获ETL跟踪，然后在xperf中打开它以查看CPU的使用情况。

要开始使用，请按照Windows性能分析开发中心的"入门"部分进行操作（http://msdn.microsoft.com/en-us/performance 。

Hi everyone. 

I'm having a problem I can't seem to figure out.  I have WinXP Pro Service Pack 2.  I've installed most of the updates from SP3 but didn't want all of them so I made them custom updates.  
I can go online and surf all I want but as soon as I log into a secure website such as Yahoo! Mail, or an online bank account, or anywhere that requires a username and password, my cpu spikes up to 100%.  I enter my username and password and then it spikes.  It will stay there for about 4-5 minutes and then it will settle down and log me into the secure website.
I have downloaded process explorer but I couldn't really figure it out.  I'm not sure how to read the threads or know if that is even what I need to look at.  I have looked at Sysinternals Process Utilities to see if there was something that could help me but I'm not sure which one would be best if any.  What I really need is something that will list each running service, dll, and anything else that can help me find out what is running when I try to log on.  I have tried to stop all services that weren't necessary to run windows and internet but still can't find the problem.  The problem is in the services.  I have uninstalled any virus protection program that I can find on my system, old and new, but still didn't fix the problem. 
Any help would be very much appreciated.

Thanks,
Teresa

Hi Teresa,

It's strange that Process Explorer didn't show you where your CPU cycles are being spent. You can try using a more powerful tool, called xperf, that comes as part of the WPT Kit available for download on this site. You'll need to capture an ETL trace and then open it in xperf to see how your CPU is being used.

To get started please follow the Getting Started section on the Windows Performance Analysis DevCenter (http://msdn.microsoft.com/en-us/performance).

Hope this helps,
Michael
