Specific web sites access problem

[trafoo]

I've fought a long battle trying to solve this irritation and have given up. I thought I'd post here in hopes sombody would have an idea what's wrong. The problem is that I can't open some web pages, while others open with no problems. There doesn't seem to be any rhyme or reason as to which ones won't open. Some examples are www.cinemark.com , personnel.ky.gov, and www.mccoyseminars.com . Now, here's the really funny part, the sites won't open using other browsers, either! I've tried Netscape, Opera, Mozilla, and Firefox, besides IE6. This makes me think it's a Windows problem. I was running Win98SE, and upgraded to XP last week in hopes it'd fix it, no such luck. Best I can recall, the problem started about the time I upgraded to IE6 from IE5.5. I've also tried completely uninstalling IE using software, and then reinstalling. Any suggestions are deeply appreciated. Thank you very much.

I was running Win98SE, and upgraded to XP last week ==upgrades are not recommended ,neve have been except by Microsoft.do a full install of XP ,you should be able to do this if you xp is a upgrade disk ,you will just need to insert the win98 disk when asked .!note you will loose everything so make backups of important things .
Also make sure you have the SP2 befor you go online to avoid getting known viruses.
download the full version here if you have a burner to copy it to disk and install it before you go online after install of XP
