Ecran bleu et plantage

Bonjour,

Voila j'ai un souci qui devient de plus en plus génant mon ordi plante de plus en plus souvent et m'affiche un ecran bleu avec des infos qui changent, des fois c'est win32.sys ou encore stop et des adresses...
Enfin bref je ne sait pas quoi faire pour résoudre sa et j'ai peur qu'à force sa abime l'ordi !
Que dire à part que sa arrive lorsque je suis connecté à internet pendant longtemps, ou avec beaucoup de pages ouvertes, msn et que j'ai plusieurs applications qui tournent.

Voila si quelqu'un connait la solution et bien sa serait fort sympathique de m'aider...merci.

Cordialement

je joint un rapport hijachthis :
