Mon PC LAG

Bonjour,
J'ai 1 petit problème : mon PC lag énormément et je ne sait pas quoi faire. Quand je démarre IE ca me prend jusque 2 min pour ouvrir la page d'accueil. Et par fois, mon ordi lag TROP et la, après une 15 de sec il redémarre. Par fois j'ai un écran bleu avec une erreur qui s'affiche(je ne me rappelle plus de quoi il s'agit).
Je crois que c'est au cause des virus, mais je ne suis pas sur. Ça peut être aussi au cause des programmes de démarrage. Si vous pouviez m'aider svp. (pardon pour mon français =) )
Et j'ai une question : je joue à Lineage 2, un jeu MMORPG et est ce que je cour des risques en jouent? Bien sur j'ai un anti-viru et pare-feu de windows.
Voila, j'ai fait quelque scan :

A, oublié de dire, j'ai windows XP professionnel service pack 2 ; 3.00 GHz ; 1.5 Go de RAM (donc sa ne doit pas lager...). J'ai mis a jour tous les pilotes, donc je pense que problème ne vient pas de la.
Merci pour votre aide!!!
