Barettes mémoires Fermé

Question

Bonjour, 

Bonjour, 
j'ai constaté un ralentissement de mon PC depuis quelques temps. Suite aux conseils de vos collègues sur un autre forum, j'ai lancé malwarebytes. 
j'ai bien nettoyé le pc, mais je n'ai pas trouvé de grosses différences sur les performances. 
est il possible que ce ralentissement provienne des barettes mémoires et si oui, comment vérifier qu'elles fonctionnent correctement ? 
mon pc est un portable acer aspire 7739zg 
RAM 4,00Go (3,68 Go utilisable) 
Processor intel(R) Pentium(R) P6100 @ 2,00GHz 2,00GHz 
SE 64 bits 
Windows 7 Edition familiale premium Service Pack 1 
Merci pour vos conseils et explications 
Cordialement

Configuration: Windows 7 / Internet Explorer 10.0

Bonjour,

j'ai constaté un ralentissement de mon PC depuis quelques temps
c'est très vague car c'est un phénomème qui affecte tous les ordinateurs après un certain temps d'utilisation

Plusieurs causes sont possibles  :

- comme tu y a pensé, ca peut etre une cause logicielle, un virus ou malware occupe beaucoup le CPU : il faut identifier le responsable et s'en débarrasser

- ca peut etre aussi un ralentissement du à la surchauffe :
l'encrassement su système de refroidissement qui est inévitable, conduit à une surchauffe et le CPU ralentit pour chauffer moins
Vérifie le système de refroidissement (il faut l'ouvrir complètement)
Pour + d'infos sur ce sujet :
mon-portable-chauffe-quelles-solutions-y-a-t-il

Enfin, meme si tout marche bien, comme les applications sont de plus en plus complexes, un PC semble ralentir au fil des années, mais c'est simplement parce qu'on lui demande d'en faire toujours davantage : 
dans ce cas, il n'y a pas de solutions, à part utiliser toujours les memes logiciels, ou changer de portable pour un + puissant

est il possible que ce ralentissement provienne des barettes mémoires
peu probable, sauf si une barrette est défectueuse, conduisant à une quantité de mémoire réduite

Pour vérifier si les différents composants de ton PC fonctionnent normalement, je te conseille CPU-Z

j'ai pas tout lu dans ce rapport hyper long (je t'avais demandé la photo des onglets CPU et mémoire), mais à 1ere vue tout semble normal coté RAM :
les 2 barrettes 2Go DDR3 1333 Hz sont bien détectées et tournent à 1066 MHz (limitation du CPU)

Seul souci éventuel, la quantité de mémoire assignée au Intel Graphics : 
Name Intel(R) HD Graphics
Memory size 1754 MB 
Ca te bouffe presque une barrette de RAM pour la puce Intel Graphics !
essaie de voir si tu peux réduire cette quantité de mémoire dans le Bios, si ce réglage est accessible
