[Resolvido] Computador não desliga e nem reinicia

Não sei se é virus ou se foi pro causa que teve umas quedas de luz do nada, várias vezes, e o computador desligava, más eu não consigo reiniciar ou desligar ele, eu coloco lá pra ele fazer a ação e ele fica naquela tela azul do windows 7 escrito ' Fazendo Logoff' ou 'Reiniciando' e não sai dai, coloquei ontem a noite pra reiniciar e hoje de manha continuava na mesma tela. Formatar o computador é a ultima das minhas opções.

Se por algum acaso for necessário formatar, continuo com windows 7 ou passo pro windows 8?

ps: Eu uso de tudo, jogos pesados, edição de fotos e vídeos, programação...
