Help! My Computer won't login to YouTube and Friendster or watch CNET TV!?

It used to work just find but for about two weeks now, my computer won't let me login to YouTube or Friendster or watch CNET TV! But when using another computer, it let's me login or watch CNET TV just fine!

The computer I'm referring to is about three years old, running Windows XP Home Edition. To browse, I use Firefox, Internet Explorer, and Safari. (If this helps)

All three browsers won't let me do these things for about two weeks now.

I already ran Computer Associates Antivirus and Antispyware and there's no malware, spyware, or adware in my computer.

Please help me! Best answer gets 5 stars.
