More than likely, you have a ton of stuff being started at boot and maybe
some malware as well.
To cut back on the number of programs starting at boot, check the programs
themselves for an option not to load. You might have to double click an
icon in the tray (others might require a right click) and then look for
preferences or options. If you cannot find an option, look for the program
in one of the following start up points and remove the reference to it:
Start up folder on the start menu, the load= and run= lines in the win.ini
and these registry run keys (use regedit.exe):
1. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
2. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
3. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
4. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
5. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
6.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
7.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce\Setup
You can use msconfig.exe, startup tab, to disable programs; however, by
doing so, you may lessen its value as a troubleshooting tool. There might
be some double entries in msconfig--leave those for your AntiVirus program
alone as they may be required.
If you disable an entry in msconfig or remove it from the start up point and
the program loads again after a reboot, that is an indication that you
missed an option on the program itself. If you don't know what an entry is,
check here:

for the item.
If you don't already have them, I recommend you download and use AdAware or
Spybot (or both) on a regular basis and consider removing everything these
programs identify. Be aware that there are frequent updates to these
programs and you need to check for them before every use including the first
time.
