On my Win 7 computer, this happens:

• I work for several hours without problems, also using Chrome
• Suddenly, just after refreshing a page in Chrome, disk starts being used excessively
• (here I can close Chrome or not, no matter, the disk won't stop)
• Disk diod is on all the time and I hear it running like crazy, all computer is a little slowed down
• It last 5-10 minutes
• In the meantime, I go to Windows Task Manager and observe what processes are using disk and turn them off one by one - but no success in stopping the excessive disk usage
• After approximately 10 minutes everything stops
• I go to Chrome (or re-open it) and refresh the page with mixed results - sometimes the whole process repeats immediately, sometimes not

Basically, it is almost always Chrome refreshing random page that starts the excessive disk usage, but killing Chrome process does not stop the disk.

Going to the same page in Firefox is not causing problems.

Windows Search is turned off.

I would like to know what is really happening. Perhaps there is a utility which would allow me to see which process is really using the disk, so that I can disable the service ? (not chrome, because killing chrome does not change anything) or even better, perhaps there is a way to fix it?
