First off - My system is an HP Pavilion 750n with a 1.6 GHZ Pentium 4 processor, 768 MB RAM and using Windows XP Home ed as an OS. I noticed around mid-September that it started taking a longer time than usual to open programs from desktop icons and to open files from My Computer and Windows Explorer. It takes about 5 minutes to completely boot up - much of that time seems to be loading the Computer Asscociates Secuirity Suite. I have done all the usual tweaks like emptying the recycle bin, temp files, doing a defrag and scanning for viruses and malware. I also ran a Hijack This, but it did not detect any problems*. The icons on the desktop are: My Computer, Windows Explorer, Defrag, Word, Firefox, IE, AdAware, Spybot, Malwarebytes, ATFCleaner, CCCleaner, Computer Associates Security Suite. Excel, MS Publisher, Print Shop, and Kodak Easy Share. I did have a new power supply installed recently because the fan was making revving noises on and off. Even the tech that did that service commented on how slow my computer was. Unfortunately, he only services hardware and could not offer any suggestions to help me with the slowness problem. I also had a new modem installed about a month ago. I get Internet access through a cable ISP. Physical memory while running is: Total - 78,000±, Available - 42,000±, System Cache - 43,000±. Processes running - 38. Startup Selection is "Selective Startup" with checks in the boxes for Process SYSTEM.INI File, Process WIN.INI File, Load System Services and Use Original BOOT.INI. The box next to "Load Startup Items" is solid green in the box (no check). I have 5 icons in the Systray Box - AdAware, CA Security Center, Volume, and Safely Remove Hardware (for my external Ethernet card). These items are checked in the Startup menu: cctray, CAVRID, cafw, capfasem, capfupgrade, realsched, AAWTray, Reader_sl and there's one box with a check in it that's on a blank line. Once I get on the Internet, it seems to work normally - I do not notice any lagging while browsing, only when I use the desktop icons and menus or try to open or move files using Windows Explorer that there is a considerable lag. Any suggestions as to what the problem could be and any fixes would be much appreciated. Assume that I am not too computer savvy. Thanks.
