Regular CPU Spikes - Help Troubleshoot


Recommended Posts

I recently installed a Sata PCI card on my old Barton IDE Mobo to fit a new 1TB sata drive.

Also I did a Windows Reinstall & sfc /scannow because of some minor issues.

Utorrent was working perfectly before, but now I get these annoying CPU spikes - other than that utorrent works well at full speed. I use it heavily with currently 4000+torrents & still adding.

I tried uninstalling Zone Alarm - no difference.

Any ideas ?

I backed up C:\ using acronis - uninstalled ZA tested - no difference - restored C:\ with ZA intact.These logs in current state with ZA.

Ok - I edited the logs above with new HJT version & fuller PE log


I Tried a fresh XP install & guess what...SAME ISSUE !!!

However, I did reimport all utorrent settings - so it coud be that - else an issue with the SIL3512 Sata controller - will do more testing...
