Strange 100% CPU usage


Recommended Posts

First off, I have looked at other threads with 100% problems.

Unfortunatly i cant seem to find a fix. :(


Prob Desc:

Usually when i open up uTorrent (Version 1.7.7) the icon appears instantly and files get checked and downloads start. This was the case this morning. However, later on i had to force a restart on my comp, since then uTorrent will use 100% cpu when loading, which is OK becuase once it fully loads it drops back down to 1%. Becuase of the restart the files need to be checked, which happens at low CPU usage. however once the first file is checked it begins to download. then uTorrent will use 100% cpu and then become unresponsive. Rather annoying.
