Ho problemi di lentezza (all'avvio, alla chiusura, per qualsiasi operazione...) con questo computer. Mi controllate il log per favore. Grazie

Ciao.
Segui le indicazioni alla lettera di questa guida:
http://forum.aiutamici.com/yaf_postst90814_Guida-per-eliminare-le-pagine-pubblicitarie-SOLO-LETTURA.aspx
Posta i log richiesti nelle modalità descritte a fine topic.

Gradirei una qualsiasi risposta. Sto diventando matto con questo computer.... Grazie

Principalmente con Explorer, ma come ho detto la lentezza riguarda un po' tutte le operazioni (avvio, apertura e chiusura dei programmi, spegnimento del computer). Premetto che questo computer si trova in Rep. Dominicana presso la mia ragazza e siccome mi trovo qui e lo sto utilizzando vorrei renderlo piu' fluido se e' possibile. Molte grazie per l'interessamento

Si' molto meglio e piu' veloce di prima. Tante grazie. Un'ultima cosa: quali sono le operazioni periodiche da effettuare per mantenere il computer "in forma"?

Di nuovo grazie e.... alla prossima!!!
