Computer is slow AND WHEN I CLICK ON MY COMPUTER THE WINDOW COMES UP BUT WILL NOT RESPOND.1 person needs an answerI do too

Your post is not very informative but normally your first troubleshooting step with those symptoms would be to do very thorough malware scanning. Post back with the results for more help. http://www.elephantboycomputers.com/page2.html#Removing_Malware Common 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 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).
