я бы начал с файла GameMenu.res (находится в папке \cstrike\resource)
открыть блокнотом и изменить содержимое на
GameMenu"
{
"1"
{
"label" ". Go For Win"
"command" "ResumeGame"
"OnlyInGame" "1"
}
"2"
{
"label" ". Leave"
"command" "Disconnect"
"OnlyInGame" "1"
"notsingle" "1"
}
"4"
{
"label" ". Player list"
"command" "OpenPlayerListDialog"
"OnlyInGame" "1"
"notsingle" "1"
}
"8"
{
"label" ""
"command" ""
"OnlyInGame" "1"
}
"9"
{
"label" ". Lan"
"command" "OpenCreateMultiplayerGameDialog"
}
"10"
{
"label" ". Inet"
"command" "OpenServerBrowser"
}
"11"
{
"label" ""
"command" ""
}
"12"
{
"label" ". Change Game"
"command" "OpenChangeGameDialog"
"notsteam" "1"
"notsingle" "1"
"notmulti" "1"
}
"13"
{
"label" ". Config"
"command" "OpenOptionsDialog"
}
"14"
{
"label" ". Real Life"
"command" "Quit"
}
}
если не поможет попробуйте обновить драйвер видеокарты
