NDIS is my problem as well. Updated all LAN drivers. Going to browse through this entire thread. Does the wireless ethernet adapter impact anything even though I'm not on wireless? Is there even a point in updating it then? hal.dll is taking pretty much also as you can see. I pmed you the etl file. Here's a screedump of latency monitor: http://dl.dropbox.com/u/11526435/latency%20monitor.png What is highest reported hard page default resolution time? Looking at the files what is your advice to fix this high cpu issue? I only have it when network traffic is involved, worse at higher dl speeds. I've done all the usual steps and beyond, updated all drivers, bios, spyware, tried other network, no usbdevices connected etc etc etc. Thanks in advance
