Computer acting strangely lately - Help please

[rlestra5]

Hey everyone,

Lately my computer has started acting very strangely and I am not sure why. The only browser I am able to open successfully is Safari. Internet Explorer and Mozilla Firefox do not open at all. In Safari, only certain websites work. When I try to open others, I simply get the message "Safari cannot find/connect to the server." The websites where this message is displayed are websites I previously had no difficulty opening. Generally speaking, the computer seems to operate at a "sluggish" speed. Even the websites that do work do not seem to load as quickly anymore.

I have tried deleting/uninstalling as many unused programs as possible that may be clogging my disk space. I have anti-virus software installed and my virus scan runs regularly. I have tried re-starting my computer on several occasions. I have de-fragged my system, cleaned up disk space, and deleted temporary Internet files and browser history when I close my browser window. I am running Windows Vista on my machine.

Please, if anyone has any advice on how to fix this problem, I would greatly appreciate it.

Thanks all,
Ryan
