100% UC utilisée

[kolorius]

Bonjour,

Mon ordinateur est assez lent, les fenêtres mettent des années à s'ouvrir et souvent elles ne "répondent pas". L'UC utilisée varie beaucoup: en un clic, je passe de 41% à 100%. C'est très agaçant.

Le problème c'est qu'il est impossible de redémarrer l'ordinateur sans qu'il s'éteigne 10 secondes plus tard. Je peux l'éteindre et le rallumer mais pas le redémarrer. Je crains donc qu'il s'éteigne pendant l'analyse ou je ne sais quoi et que cela ait des conséquences.
