Some time ago I noticed a problem with my Windows XP Pro. While browsing MyComputer the folders window freezes / hangs / does not respond anymore. The taskbar also becomes unresponsive. The only thing I can do is to kill the process. Of course this is not a good solution. Fortunately running chkdsk does not report any problems on the drive after that.
I found a post on another blog regarding this problem with some possible solutions and I would like to share it:

I have done the first two steps and will watch if this has solved the problem...
