This seems to have started about a month ago.
WinXP SP3 (fully updated)
IE 8 (fully updated)
Processor: 1.73 GHz on a Dell Laptop
Memory: 1.25 GB
I am using Windows Task Manager's Performance tab to monitor CPU Usage History.
For some reason certain websites peg the graph all the way to the top -- or 100% CPU usage.
This happens even when I run IE with no add-ons and my AV & ad blocker software disabled. I've scanned for viruses and malware. I've even set all my IE settings (Security & Advanced tabs) to their defaults.
Here's a sample website where I see the problem.
But strangely enough, this site with far more graphics than the 'tvnewser' site (shown above) does not require 100% CPU usage..
Finally and perhaps most significantly, this does not happen with Firefox.
I have 20+ years with Microsoft software, including development tools, and can usually solve most problems. But frankly, this one has me scratching my head.
