Hi Chris and Ale52. Thank you so much for your responses.
I discovered that AIM sits in the system tray when I boot WinXPPro, so I have disabled that function.
I have the latest Service Pack 2 and all updates (except IE7).
Here are the specs for my Powerspec 8920 computer (Micro Center's brand), bought in June 2002:
Intel® Pentium® 4 Processor 2.40GHz
Microsoft® Windows® XP Professional Edition
System Board: Intel® D845EBG2
System Memory:512MB composed of 2 - 256MB DDR266 SDRAM 184-pin DIMMs
MadDog Conqueror Nvidia FX5200 Plus Graphics Card
The problems started occurring I guess (but not sure) either Mar or Apr and have gradually gotten worse. Before then, all worked fine. The only new item in the Systray is the small utility MemInfo, added Sat. June 2nd (see below).
Items in SysTray:
Logitech Quickcam10, AVG Antivirus Free Edition-Control Center; Window Blinds 4.5; Post-It Notes Lite; Webshots; Live Weatherbug; Yahoo Widgets (without the Dock); and a small utility called MemInfo 1.80 (Service Release 3; as of Saturday June 2).
I have closed various items to see if any of the above are significantly draining the memory, but they all seem to individually not having much affect. When I do open Firefox, my CPU usage jumps to 100%.
I have a CD program that I use called Chant the Bible which, when in use, uses 100% CPU...functions, but a little slow.
Contrary to false statements Weatherbug does *not* contain spyware or adware.
At the moment with the latest Firefox Browser opened (with 29 tabs open), my Memory Usage is 81%.
Advice requested: I checked into replacing my Memory with two 512 DDR RAM 2700 (333Mgz) for a total of 1 Gig. Should I do this? That is what I found at the computer store.
Also, I run Windows Defender, SpyBot Search and Destroy, and Lavasoft Adaware weekly and update and Test AVG Antivirus daily.
I certainly appreciate the friendliness of this forum and both of your quick responses! All advice is greatly appreciated, since I'm not a "techie" (although I do occasionally use Linux: Mandriva 2006 on Desktop, soon to be changed to 2007 Spring, on a separate harddrive).
