Vista Internet/ Networking Issues

Well, the internet was working fine on my PC, and I was so amazed at how fast the PC was. After 5 days however, the network connection failed. Firefox and IE told me that although the server seemed valid, they could not establish a connection. Thinking I had been a victim of the Integrated networking going bad like half the others on Newegg, I bought a Rosewill PCI Card. Still didn't work. Uninstalled AVG, tried Direct to modem, changed about every damn setting Vista would let me. (Which is not very many.)

So now, I'm on Ubuntu 8.10 on CD, and the Internet works fine. Pissing me off, because I have no idea HOW to fix Vista.

Any ideas??

Two more significantly more minor questions:

How do I change how much RAM my GTX 275 takes out of my system? Because it's taking over 2.8 Gig for God's sake. Also, why does Task Manager tell me that I only have 5MB Free RAM on average although it says I'm only using 2-3GB RAM?

What are your complete system specs? How much RAM do you have installed? What version of Vista are your using (32-bit or 64-bit)?

You'll probably get more help in the networking section of the forum. Do you have a third party firewall installed? Do you have a yellow exclamation mark by any of your hardware in the device manager? Have you installed all the latest drivers for the motherboard from Gigabyte's website?
