Windows HUD not displaying when I boot PC?

Hi, I'm running Windows XP SP3 (If that helps)
And sometimes when I boot my PC, it loads fine but then the HUD doesn't display?
I can open up task manager with ctrl + alt + del fine and it responds to my iphone being plugged in
Why is it doing this?

Added (1). I'd define the HUD as start, toolbar, time and date
Also, the items on my desktop don't appear
My computers specs are
CPU: Amd athlon ll x4 640 (3.00GHz)
GPU: HD 6670
8gb RAM
1TB hard drive
(Can't get motherboards name without opening it up)

A "HUD" is a "Head Up Display"? What type, brand, model? What is the "PC"? What connection between it and "HUD"?

  • Why is my iPhone 4S not displaying the status bar when I'm on Safari? I was on YouTube and then I look up and the status bar on my iPhone wasn't there! It's there on any other app but on Safari it totally disappears. What is wrong with my iPhone? No my phone is new. I got it for my birthday about 6 months ago. It was in its box and my parents got it at best buy. So it's not jail broken.
  • Not displaying caller ID (iPhone 5)? There's a feature on the iPhone 5 where you can choose to not show your caller ID when making a call. Would that reflect on the call logs on the phone bill? Will it not register in the history?
