I recently re-formatted my Dell Dimension E521 Desktop (Windows XP) to clear it of all problems, and start off on a clean slate. The only things I've installed on it are:
a few old games (like RollerCoaster Tycoon, all from CD)
I have the newest version of FireFox. What happens is randomly (it happens _every_ day), my Internet Explorer cannot connect to any web pages, and FireFox just says (Untitled) for every page (page displays blank). Cannot search for anything, etcetera. When this happens, I cannot connect to Diablo II Battle.net, either.
However, Pidgin still works and I can still use it to connect via MSN, AIM, IRC, etc. I go to my connection and it says that it is connected, and I repair it and it says that it's fine, yet it still will not connect. The only way to connect again is to restart my PC. I have tried disabling Shockwave in FireFox, and turning off all Firewalls but nothing seems to work!
