Halo PC for my computer is not working...I dowloaded it and have GameSpy to choose games with: no luck still?

I have downloaded Halo Combat Evolved for the PC, and I also have also downloaded GameSpy which is suppose to let me play the Halo game on the internet with multiplayers. But when I click on a game being offered in GameSpy, it begins to load then says, Network Connection Lost. What can I do to resolve this problem so I am able to play the Halo PC game on the internet with other players? My computer is on a single network (home computer).

Maybe your firewall is doing that. You disable that?

If your computer is not working properly when it is switched on, there is a hardware problem. Most of these problems can be solved by just opening up the computer and removing the dust. Detailed instructions at http://tinyurl.com/yd34oj

wow.. thats sad. umm.. i dont really know how to fix it, but you can try asking an expert on that.. lets say the guy you bought it from, he might know, but if still no luck try going to google and search for something like that..
