The disconnection problems sound like there are a few causes. The 15 minute problem is probably due to a firewall configuration error. Most likely because it's set to block the connection after a certain amount of idle time. To connect to counter-strike servers, you'll have to manually set rules to allow C-S to access the Internet and/or act as a server (depending how C-S works... I haven't used it before). Finally, about the reseting your computer after a day... it's most likely due to a IP address issue. Next time you would normally reset, try going to the Run menu under Start and type: ipconfig /renew Then try to access the Internet and see if that works. It sounds like the lease on the IP from the modem is only 24 hours.
