ccsvchst.exe high cpu usage

I have a compaq presario, Windows XP SP3 and NIS 2007

 

I never had a problem until the last week or so. When the PC comes back from sleep mode, I often find that ccsvchst.exe is using 99% of processor capacity and I have to shut down to sptop it.

 

I know this has been an issue in the past, but I never had it with NIS 2007 before.

 

I think the problem is just associated with sleep mode, but I can't be certain, but it has not happend while I am actually using the PC.
