I'm using Microsoft XP Home Edition 5.1, AMD Sempron 3000+. My internet provider is Qwest Broadband, although I highly suspect my computer being the trouble. I have isolated it, since two other computers have hooked up to it's wireless, and they work absolutely charming. However, I'm NOT using wireless. I still believe it is my computer, as: Within the first 2 or even 5 minutes of a restart or bootup, it will load everything I put into it. After this time it will slowly degrade. After leaving the computer on for 20+ hours, nothing will load.
There is one more factor; About every 3 months if I don't turn the modem off (Ever, not even for a quick reset), the internet will then work and load every page I command it to regardless of how long the computer has been on. This 'behavior' turns off again in about 3 months, or if I turn off/reset the modem. This clarifies that computers have separate minds. {For reference, sites like Youtube and Google are the first to go; and Imeem and MSN are last}
I'm moderately experienced with computers, but this one absolutely stumps me and my pals. I'll appreciate any help, but especially to who solves this.
