For some reason ever since 3 days ago my PC will loose the ability to communicate overports 23 and 80 after running for an hour or two. It also looses the ability to communicate over other ports, FTP being one of the only things I can do when it does this.
I have to reboot to fix the problem for another hour to two. I have had to remove my switch/gateway because I would only get a few minutes of internet/network use connected to it (I have been using it for over 7 years). With my PC directly connected to the DSL modem through an networking cable (not usb) I get the hour to two of use, but cannot talk to anything else on the network, nor can the other PC use the internet (because the internet is no longer connected to the network when it is plugged into my PC) so this isn't a very good fix. Trend Micro says I have no viruses, I also do not have any visable spyware.
Any ideas? My only thought right now is maybe something is going wrong with the built in 1G/100/10 internal networking chip?
I'm kinda out of ideas and do not want to start replacing hardware until I have to.
