Slows Computer down

Thank you for your reply.  I have another question. Does anyone else have this problem I’m about to explain.  It seams that when ever I come onto this message board after about 5 minutes or less my system starts to slow down and my mouse and keyboard go into like a delayed mode.  Almost like I remember some of my old systems when I would go on the net and I had to empty my cache mem.  Real strange.  Then I end up having to reboot and it’s ok.
