Problem with windows xp taskbar

I have read some of the threads on similar problems but could not find a fix. I am running Windows XP Media center with SP2. Without making any changes the taskbar started to take 20 min. to load. My Start button, Windows Defender, wireless icon, and Avast icon appears right away during bootup. The volume control icon appears after the taskbar completes loading(20 Min). Windows Defender is set to not auto scan.
So far I have run scans with Avast, Windows Defender, Spybot, Malwarebytes, HiJackThis, Ccleaner, and SuperAntiSpyWare. Everything says my system is clean. Also checked bootup with Bootkit Remover.
I tried to run Microsoft Bootvis, but can't get it set properly to show what the drivers and bootup are doing. It only scans Disc I/O and Process creates.
Any help would be appreciated.

So, the problem started suddenly, compared to quick load times before?

 

Hey guys! Problem is solved!!$%^. I feel like an idiot. I will post this just in case it will help someone else. About a month ago I uninstalled Power DVD 9. Apparently something did not uninstall properly. I don't know why the slow loading problem just started, but since my audio was working ok I never thought to check anything audio related. Under the sound and video controllers i had several of the yellow exclamation marks. Reinstalled the drivers from the os disk and everything is back to normal. 1 min. startup!
I would still appreciate a tutorial on how to set bootvis to trace the driver delay and boot activity.

Thanks

I overlooked the reply from Halo on running bootvis. Thanks for the info.
