TeamBundy: My daughter had blubster running, which was a site for downloading music onto her I-pod. I also have Zonealarm running constantly as well, that had a bit of a glitch in it but it is sorted now. Now and again my screen freezes as well, like you said for a matter of seconds, sometimes there is no reason for it, it could be your ISP just slowing down and then kicking itself back in again.

Hmmm i am now wondering if this could be and we should take it to the computer board. If i can be of any further help please let me know.
