I recently installed Windows XP Pro on my machine. Whenever I powerup my machine or even do a reboot, the taskbar is not "normal" it is gray, and plain. Usually the start button is green with the windows logo, and the bar is blue, etc. Can anyone tell me why this is happening, and what I can do to fix it? Thank you in advance for all your input.

I had windows 2000 professional. When I started the install process I was asked if I wanted to dual-boot or reformat. I selected to reformat that partition of my hard drive. It wiped everything out on my C drive. I am guessing that it was a clean install, since I didnt actually upgrade. Any other ideas? Thanks!
