Hello. My sister has a Dell Dimension 2400 with a 2.2Ghz Celeron, 128 MB RAM, and running Windows XP Pro. She is away at school, and I have no actual access to it. The main problem is that she is unable to view any websites. She has a cable connection, and she cal still use AIM, so I know the computer can get online, but every time she tries to go on a site, all she gets is a white screen. The computer was recently formatted and Windows XP Pro was installed on it by a professional. I am at a loss as to what the problem is. Any help is great. And second, as I stated, it only has 128 MB of RAM. I am going to get more memory for it, but does anyone know exactly what RAM is needed to a Dell Dimension 2400? I believe it needs SDRAM, but I do not know exactly what to buy. Thank you for your time.
