Ecran bleu, plantage, lenteur

Bonjour

Depuis hier, j'ai quelques problèmes avec mon ordinateur portable (ACER Aspire 5102 ZLMi). Alors qu'il fonctionne normalement apparait un écran bleu sur lequel j'ai juste le temps de voir ce message erreur KERNEL_STACK_INPAGE_ERROR alors que le reste des lettres est du charabia. Je dois préciser que mon ordinateur est une version grecque.

J'ai fait un controle grâce mon antivirus AVG (version gratuite) dont voici le rapport :
