Well for Registry Cleaners you can use CCleaner, Registry Repair, or Registry Mechanic. I use both CCleaner and RR.
Your system isnt too bad. But Norton might be eating up a few resources so when your running WMP, IE and Something else that could be why you run into this.
My system isnt that bad. P4 3.4GHz HT with 1.5GB DDR2 RAM. Got all sorts of other trimmings too. I have done CS2, Opera, WMP, and had CSS running all at the same time. Not to mention the firewall, antispyware, AV, Steam and few others that run. So i do a lot of multi tasking with no problem.
