Probleme avec mon PC

J'ai de gros problèmes avec mon PC.
Très souvent il beug et me plente tout, je ne peu plus rien faire sauf écrire sous word (c'est déjà pas mal ... mais je ne fait pas que du traitement de text)
on m'a conseiller de me rencarder en faisant passer ma config PC.
Alors la voila, si quelqu'un peu me rencarder ça serai cool :
