Holding the curser over the system tray reveals an hour glass that lasts for over two minutes right after switching on the PC.Even after the hourglass disappears, any application is really sluggish to open or appear for the first ten to fifteen minutes.We run AVG antivirous & firewall and are always current w/ updates and virous scans1 person needs an answerI do too

AVG alone is not enough. See Item 2 for that. Some reasons for computer slowness: 1. Computer hasn't been maintained - http://www.elephantboycomputers.com/page2.html#Maintenance 2. Computer is infected with malware - http://www.elephantboycomputers.com/page2.html#Removing_Malware 3. Hard drive is too full. Remove unnecessary stuff, uninstall unused programs. Don't forget to back up! http://www.elephantboycomputers.com/page2.html#Backing_Up 4. Flaky third-party software. Toolbars and add-ons are particular culprits in this area. Uninstall toolbars (Google, Yahoo, ISP-branded, etc.) and look carefully at what add-ons are in use in your browser(s). 5. Computer has too many unnecessary programs/processes running in the background. Manage your Startup: For XP - How to Troubleshoot By Using the Msconfig Utility in Windows XP - http://support.microsoft.com/?id=310560 The free Autoruns program is very useful for managing your Startup - http://www.microsoft.com/technet/sysinternals/default.mspx For Vista/Windows7 - Start Orb>Search box>type: msconfig and when it appears in the Results box above, right-click and choose "Run as Administrator". Autoruns is also very useful. 6. User is running a bloated/invasive antivirus program such as ones from Norton and McAfee. Replace with a better program. I recommend either NOD32 (commercial) or Avast (free). Avira is also good but the free version has an unpleasant nag screen (Google for instructions as to how to disable this). User may also be running more than one real-time antivirus/firewall/security program. 7. User has installed new programs that are processor and/or memory-intensive (Photoshop, AutoCAD, Mathmatica or the like) and doesn't have the necessary hardware power. 8. Hard drive is failing and is in PIO Mode. This is very dramatically slow (like being back in 1985).
