I have been having a lot of the same errors that many XP gamers have been having. Like "counter-strike net send packet error no error" or the game just stops and the monitor goes black. This is what I did to resolve these errors. They worked for me and I was able to play for two and half hours yesterday with no problems. 1) Uninstall Qos packet scheduler 2) Go to Services and disable all unnecessary services that have to do with the network or a LAN. If you don’t know you should search this forum or the Internet and disable or make manual the necessary services. 3) Check you your modem configuration and make sure that the option to disconnect if idle to long, is unchecked and Qos packet scheduler is uninstalled. Sorry I wasn’t able to provide specifics on how to do each step but there is plenty of information on this forum and the Internet on how to do it. I am now playing with no problems.
