Hi,

I've had a problem recently with 100% CPU usage when on the web. I usually use Chrome, but problem is similar in Opera, and in Firefox. My computer is running Windows XP SP3. I have tried disabling Flash and Java, one at a time or both. A few times it seemed to solve the problem, but that was short-lived. I tried uninstalling Java and downloading latest version, no improvement. I would appreciate any suggestions. I was referred to this forum from hijack this, and have a log from that.

Thanks for any help you can offer.

Are you saying that...anytime you get on the Web...with any browser...that you have 100% CPU usage for a sustained period of time that is measureable?

What proecesses are (primarily) involved in this usage, per Task Manager? What are the 3 line items reflecting the highest percentage of CPU use?

FWIW: There is no use malware logs in any of the O/S forums, those are entirely different issues...for trained personnel working in our malware forums.

Why did you uninstall Flash and Java?

Have you looked at/disabled...your browser add-ons...when trying to determien suspects?

Louis

It's not always immediate when browsing, but usually within the 1st few minutes. It doesn't matter which of those 3 browsers I use, and I don't have IE installed to try. 100% usage remains high some times, and drops down at times. Browser freezes when it's at 100%. I am typically a user with lots of programs open, lots of browser tabs, with rarely any negative performance. It's currently not a problem with this forum, but fairly often goes to 100% even with no other programs open.

Highest peak memory usage is chrome, svchost, and EKRN.exe (my latest attempt ESET NOD32).

I didn't uninstall Flash, just disabled or blocked it in each browser. Same with Java, then tried an uninstall and renewed download. I read somewhere these may be a problem, and I noticed more usage spikes when on pages with either of those, less issues on plain no-frills web pages.

I had a problem with Chrome speed dial about a month ago, and disabled that. Otherwise, I don't use too many add-ons, but will look into that tomorrow.

Is it appropriate to post my original question in a different forum?
Thanks for your comments/suggestions.

Hi, I use Win 7 and I have same problem. I don't have 100% CPU usage, only 25%. I have quad core CPU and all browsers use to slowly increase their CPU usage up to 25%. It doesn't matter, if I set affinity for browser to 1 core, or split it to 4 cores. It always end at 25%. After that, browser is unusable, but system and other applications run OK (maybe little slower, if they need more CPU). The most interesting thing is, I have same problem in Linux (on same PC) too and only with browsers. Everything else runs OK. It is strange.
