I've noticed my laptop runs rather sluggishly for the first 20 minutes when booted up. When I examine the taskmanager I find several SVCHOST.EXE in the processes running (which I have read can be bad or normal, very generic) and one of them is always using 150,000-200,000 k of my resources (causing the slowdown i must assume). When I terminate the process my speeds go back to normal, but for a second the task bar reverts from the normal XP blue to the classic WIn98 look, then comes back to normal. And also the sounds stop working. If you try to play a file in mediaplayer for example you get an error message "there is a problem with your installed sound device". sounds work fine if you don't terminate the SVCHOST process so it seems very clearly linked to that.
I've tried MAlware Bytes, HitmanPro, and AVG to try and find what could be causing this but they never find anything. How can I determine what is causing this SVCHOST to hog my resources? This is a Dell Laptop latitude d610 running XP SP3.
