Ho il pc che non si avvia in modalità normale ma, solo in modalità provvisoria. Ho cercato di fare dei ripristini di configurazione di sistema e purtroppo non succede niente. Qualcuno può dirmi che cosa succede e come risolvere il problema?
Grazie

Di seguito se può servire il log di hjt:

Se riesci a collegarti online la prima cosa da fare è una scansione con Malwarbyte's free e successivamente con DrWeb cureit!.

Questi sono da fixare:



Questi siti li hai segnalati come siti sicuri, se non li conosci fixali:


Di conseguenza se non conosci asia.msi.com.tw fixa anche questo:


Fai una bella pulizia (anche del registro) con Ccleaner dopodichè riposta il log che c'è da fare altro

Per fixare le voci che ti ha consigliato meme 1580 con Hijack devi farlo in modalità provvisoria perciò non ci sono problemi,per Maslwarebytes il discorso è diverso perché dopo averlo scaricato lo devi aggiornare prima di fare la scansione.
Altra cosa da fare prima di tutto disattiva il ripristino di sistema e tienilo così fino a che non hai risolto i problemi.
Un consiglio strettamente personale:Salva i dati e formatta e dopo aver reinstallato i service pack compreso il 3,gli aggiornamenti e i programmi base fatti un immagine del disco con Macrium Reflect così se avrai problemi in 20 mn rimetti tutto a posto.
P.S.Installa il Sp3 altrimenti tra poco tempo non riceverai più gli aggiornamenti di Windows Xp.

non e' che hai usato (tu o qualcun altro) un programma apposito che serve a far partire il pc in provvisoria o standard? In questo stesso sito trovi un programma che si chiama BOOT SAFE, e' semplicissimo da usare e serve appunto a far partire il pc nella modalita' che serve, installalo, settalo con la modalita' normale e riavvia, vedi che succede.

prova,se vuoi,ad entrare come per andare in modalita' provvisoria,ma scegli"ultima configurazione sicuramente funzionante"e vedi che succede.

proviamo,se ti va e se il pc te lo lascia fare,uno scandisk:
Inserisci nel lettore il CD di installazione di XP.
Riavvia il pc, e se il bios è impostato per far partire da CD, si riavvierà da CD.
Lascia caricare i Driver e tutto all'installaer.
Ad un certo punto dell'installazione ti viene chiesto se procedere con INVIO o con R

Premi R

Ti verrà chiesta una pwd di Admin, (al 99% dei casi non c'è) dai semplicemente INVIO,
se invece c'è, inseriscila.
Scegli con i tasti numerici sopra le lettere, non quelli del tastierino numerico,
l'installazione di windows che vuoi riparare, ad es, se è

1 C:\Windows

devi selezionare 1

Poi, dai questo comando, per impartirlo, dopo averlo digitato, dai invio)

CHKDSK D: /R


Aspetti, anche un bel po'.
Quando finisce, digita:

CHKDSK C: /R

Quando termina, digita exit per riavviare il pc.
Togli il CD dal cassettino, prima che venga caricato il BIOS, e il pc caricherà il SO da HDD.
