problema con internet

[average]

il mio PC (win xp sp2) si disconnette da internet ogni tot di tempo , molto spesso a dire la verità. succede ormai da mesi, ma non ho ancora capito da cosa possa dipendere. in pratica, ogni tanto si disconnette, e non posso più spegnerlo da Start ma devo x forza usare il bottone esterno del PC . inoltre quando lo riavvio, devo reinstallare i preferiti di Firefox con Mozbackup ... non so, sono solo indizi, magari qualcuno di voi sa cosa sta succedendo al mio PC ? altri sintomi sono un rumore forte della ventola ...

boh, se qualcuno mi può aiutare , GRAZIE !

tu dici che c'e presenza di dialer?allora procedi cosi':

scaricati hijackthis da qui---> http://www.angololibero.it/software/...ijackthis.html
avvialo,clicca su do a system scan and save logfile,fara una piccola scansione,uscira' un logfile con delle scritte,riporta tutto qui con un copia|incolla.

Il rumore forte della ventola mi fa pensare che tu abbia una ventola di raffreddamento che si sta rompendo; in genere questo provoca il surriscaldamento del componente che lei raffreddava (in genere uno tra questi: Processore, Scheda video, Chipset, Alimentatore) con conseguente blocco del pc.

Il fatto che tu debba reinstallare i preferiti di Mozilla è a mio avviso solo la conseguenza del fatto che stavi navigando mentre il pc si è bloccato...

posto il logfile sotto, ma dubito serva al mio problema ... shores, il PC non è che si blocca. io posso continuare a usare i programmi (word, autocad ecc ) ma non navigare o scaricare ...
