Problemas após instalação do SP2

[/...]

Após a instalação do Service Pack 2 para o Windows XP, ao iniciar sessão no meu utilizador as barras de tarefas e o menu iniciar não apareciam.

Então abri o gestor de tarefas e terminei o processo "explorer.exe". De seguida executei o processo que tinha terminado anteriormente. A situação continuou igual.

Como resolvo este problema?
