ok - so here's the deal - after literally rebooting my machine 8,000 times in the past 24 hrs... It seems my explorer.exe is always at 35,000-40,000K in Task Manager, regardless of what I have turned on or off in msconfig. By turning everything off (service and startups) and switching the items on one by one, I have narrowed down the list of possible culprits to the following, but cannot seem to identify the one (if it is only one) that consumes so much CPU Memory Useage in Task Manager, so I may need your advice: Services: * PC Tools Auxiliary Service (do not recall ever intentionally installing this) * PC Tools Security Service (do not recall ever intentionally installing this) * TSM Central Scheduler (I uninstalled Tivoli Storage Manager years ago, this seems to be leftover) * TSM Client Acceptor (I uninstalled Tivoli Storage Manager years ago, this seems to be leftover) * TSM Remote Client Agent (I uninstalled Tivoli Storage Manager years ago, this seems to be leftover) Startup: * Boingo (software used to find wireless signals in airports - don't care if we remove it) * iTunesHelper (I never use iTunes - can remove) * hpgs2wnd (this is a Hewlett Packard leftover from an old scanner I had, no need for it) * Google Toolbar Notifier (do I need this?) Any advice would be great - my computer is running smoothly and quick right now with the above list turned off in msconfig - if I can get rid of them all with no bad side-effects, then that is fine with me! Thanks, Broni.
