Le rapport ne montre rien d'infectieux.

Relance HijackThis, coche cette ligne et clique sur le bouton Fix checked, en bas à gauche :

R3 - Default URLSearchHook is missing

Ce type de problèmes est plus hardware que logiciel ou infectieux. D'où ton post en hardware je pense.

Alimentation ?

bj,
Cela peut être un cas typique de suréchauffement du CPU qui se bloque grâce à une routine de protection. et qui se remet en route quand il est revenu à une temp. normale.

Solution:
- Eteindre, ôter le câble d'allimentation etc
- démontage + nettoyage au pinceau et aspirateur de toutes les poussières, ventilos
- souffler soigneusement l'alim. depuis l'intérieur du boîtier, sans l'ouvrir
- Attention au CPU et à son radiateur qui sur les machines de marque sont collés au moyen d'une colle qui devient souple et déformable à partir de 60 °C, mais qui. au démontage - remontage, peut empêche le cpu de plaquer sur le refroidisseur...
(Solution nettoyage à la benzine des 2 surfaces et utiliser de la graisse thermique spéciale achetée chez un fournisseur de matos)
- Souffler le radiateur du CPU
- Pour les mauvais contacts possibles: Retirer et replanter toutes les cartes, les mémoires et les câbles des 2 côtés.
- Vérifier le serrage de toutes les vis
- un fois que tout est en place, sans capot, remettre les connections en place et finir par le cordon d'alim.
et ré-enclencher et examen.

Si problèmes persiste,
- éteindre
- Ôter
-- le cordon d'alim. et
-- toutes les cartes non indispensables
-- ré-enclencher et examen dans cette configuration

Si le problème persiste
- Faire un test de la mémoire avec MEMTEST86

Si le problème persiste faire appel à un vrai connaisseur...si si cela existe
bbye

salut

télécharge everest 2.20 ; tu l'installe et tu fais : ordinateur =>sonde et copie colle le rapport obtenu stp

as tu un flux d'air adéquat dans ton pc ? http://www.matbe.com/articles/lire/243/optimiser-son-refroidissement/page6.php

depuis combien de temps ton processeur est il installé sur ta carte mère ?

Salut

Comme dit ci dessus faut d'abord voir la température du CPU juste avant l'arrêt si surchauffe la carte mère doit couper le jus et se mettre en sécurité

Autre cause possible défaillance de l'alim qui arrive en fin de vie à la moindre fluctuation elle se fâche

salut
pour cela le rapport everest va nous donner les tensions et T°
