PC ist sehr langsam und stürzt häufig ab
 

Hallo!
Mein PC ist ca. seit einer Woche furchtbar langsam geworden und stürzt oft ab. Wenn man den Arbeitsplatz öffnen möchte, dauert es meistens erstmal eine halbe Minute bis er die Symbole einblendet... :kloppen:
zu meinem PC:
Windows XP Professional Version 2002
Service Pack 3
Dell Dimension DIM 3000
Intel(R)
Celeron(R) CPU 2.40 GHz
512 MB RAM

Ich habe wirklich wenig Ahnung von PCs, deshalb hoffe ich, dass ich alle Informationen angegeben haben die wichtig sind!?!?
Ich habe auch schon ein Hijackthis Logfile erstellt:
