Titolo: Non si avvia più winxp aiuto!

Salve a tutti, oggi pomeriggio stavo installando un programma quando
tutto d'un tratto il computer si riavvia e si incanta subito dopo il
conteggio della ram, senza dare più segni di vita.
Ho tolto un modulo di ram e sono riuscito ad andare avanti solo che
appena si tenta l'avvio di windows xp tutto salta e si ritorna al
conteggio della ram in un ciclo perpetuo senza fine.
A cosa può essere dovuto il problema? Io ho pensato a settori
danneggiati dell'hd ma la scansione fatta con scandisk su c: non ha
rilevato alcun settore danneggiato.
Come posso risolvere?
Grazie, ciao ciao.

parti in modalità provvisioria e disinstalla il programma incriminato
ciao

Difficile dirlo senza vedere.. potrebbe pure essere che installando 
l'applicazione hai installato un virus.. o potrebbe essere qualcosa di 
hardware (tipo la ram) morta.. non ho capito cosa intendi per "tutto 
salta".. se ti da schermate blu o meno..
Comunque un ottimo tool per testare l'hardware e' ubcd, ti scarichi l'iso e 
la metti su un cd (o anche minidisk, siccome e' piccola) boottabile e  nel 
bios dici di partire da cd invece che da disco. Una volta partito da CD, 
usando ubcd troverai vari tool di diagnostica del tuo hardware.. ci mette un 
po' a macinare tutto, ma alla fine molte volte ne salti fuori cosi'. UBCD e' 
free, e puoi scaricarlo su 
http://www.ultimatebootcd.com/download.html
In caso non dovesse essere qualcosa di hardware (e per quanto ho capito io 
forse ti si riavvia solo), potrebbe essere un virus..
Ti fa partire in modalita' provvisoria? Se sì, prova e magari fai una 
scansione con l'antivirus.. e poi puoi digli di ripartire da un punto di 
ripristino precedente all'installazione di quel programma (Programmi - 
accessori - utilita' di sistema - ripristino configurazione di sistema) - 
non si sa mai che il virus sia nuovo e non venga ancora rilevato dagli 
antivirus, anche se non credo.. dal suo comportamento non sembrerebbe una 
new entry :D) -
In caso non partisse dalla modalita' provvisoria potresti tentare la console 
di ripristino.
Tempo fa trovai uno stupendo documento online sul ripristino di un sistema 
windows praticamente alla frutta.. E' una procedura un po' lunga, l'ho fatta 
solo una volta in vita mia su un pc di un'amica e c'ho messo parecchio 
tempo.. pero' ti potrebbe salvare dai guai.
Nel documento era spiegato come fare quando ci si trovava di fronte a 
schermate blu e non c'era modo di far partire il sistema operativo, nel tuo 
caso sia che si tratti di schermate blu o di semplici riavvii il succo e' lo 
stesso: nel documento fondamentalmente spiegava come far partire da un punto 
di ripristino precedente usando la console di ripristino e pulendo un po' di 
zozzerie cercando di perdere mano dati possibili.
Siccome non trovo piu' l'URL di quel documento, te lo incollo di seguito 
(chiedo venia..)
.. ah, e' in inglese.
Buona fortuna

   PC users, you all know what it is: That dreaded Blue Screen of Death. 
That's right, the BSOD. You've installed a seemingly innocent application, 
restarted your computer, and suddenly you see this horror in front of your 
eyes:
         A big blue screen with some cryptic message on it. Try restarting 
again, same thing. You're dead. What will you do? What WILL you do?? Well, 
don't let it ruin your day. Remain calm.
        If you're using Windows XP, I can help you fix it. Come with me, 
down into the bowels of Windows XP, where only the high priests go. It'll be 
fun!
       I'm going to show you how to bring your computer back to life, and 
restore it to the point where things went south. You might want to print 
this article and squirrel it away for that fateful day when this happens to 
you.
        Or if you don't want to print it (and who prints anything these 
days, anyway?), and you get a big ugly blue screen, just get on another 
computer somewhere and come back to this Web page for comfort and advice.
 I can get you out of this mess. I know, because I was in the same mess and 
I got myself out of it.
    Here's what to do: First, get the Windows XP CD you used to install your 
operating system. By the way, this routine only works with Windows XP, 
either Professional or XP Home Edition.
      If you don't have a bootable XP CD, get one and have it with you at 
all times, because you never know when the dreaded BSOD might strike.
But before you do anything with that CD, try restarting your computer again. 
Sometimes, for some odd reason, this works.
        Usually not, though. If you've tried that and everything else you 
can think of, and you can't even boot into Safe Mode, this is the mission 
for you.
        Put the XP CD in the drive, and restart. When it says "press any key 
to boot from CD," go ahead, press any key and you're on your way to 
recovery. The Recovery Console, that is.
      If it doesn't give you a choice to boot from your CD drive, go into 
your computer's BIOS and make the adjustment for it to boot from CD.
        PCs brands and motherboards are too diverse for me to give you 
specifics on this, so follow the prompts and you can make that CD boot 
happen without too much trouble.
        Look at your screen when it boots up, and it always says "hit DEL 
for BIOS settings" or something similar. If you can't get it to boot from 
CD, just give up and call for support or take your computer to the nearest 
computer store for professional help.
OK, troops, are you still with me? Good. It'll look like you're 
re-installing Windows XP, but don't worry, you're not.
            This is just a screen showing you that your computer is loading 
enough files from the CD to actually do something, anything but that awful 
blue screen.
            Now when you see the screen that asks you if you want to install 
Windows, don't! Just hit R for recover, and you'll see the ominous Recovery 
Console.
            Don't let that intimidate you; the Recovery Console is your 
ugly, black-suited friend. It will have a dark, bleak screen, with the 
following stuff:
Microsoft Windows(R) Recovery Console
The Recovery Console provides system repair and recovery functionality.
Type EXIT to quit the Recovery Console and restart the computer.
1: C:\WINDOWS
Which Windows Installation would you like to log onto
(To cancel, press ENTER)?
          Go ahead and hit the number 1 on your keyboard, or whichever 
number corresponds to the operating system you were using when havoc struck. 
Enter your administrator password, and then hit enter.
You're in! Now it's time to run with the big dogs! Do not be afraid, dear 
reader, I am here to help you.
If you type the following commands into your computer, it will work magic, 
akin to going back in time.
            There are three parts to this process, but believe me, they take 
much less time than reinstalling Windows XP and all your applications. So 
follow along with me, and keep in mind that each command must be typed 
exactly as you see it here.
            Please note that this procedure assumes that Windows XP is 
installed to the C:\Windows folder. Make sure to change C:\Windows to the 
appropriate windows folder if it's at a different location.
The copy commands will answer you with a little "file copied" message. The 
delete commands just move on to the next line.
           Because of the way your Web browser displays individual lines, a 
command might look to you like it's two lines, so I've separated each 
command by an empty line.
          But anyway, type the whole command in one line, and when you've 
finished typing that command, hit the Enter key. Be sure to include the 
spaces I've included between each word here:
md tmp
copy C:\windows\system32\config\system C:\windows\tmp\system.bak
copy C:\windows\system32\config\software C:\windows\tmp\software.bak
copy C:\windows\system32\config\sam C:\windows\tmp\sam.bak
copy C:\windows\system32\config\security C:\windows\tmp\security.bak
copy C:\windows\system32\config\default C:\windows\tmp\default.bak
delete C:\windows\system32\config\system
delete C:\windows\system32\config\software
delete C:\windows\system32\config\Sam
delete C:\windows\system32\config\security
delete C:\windows\system32\config\default
copy C:\windows\repair\system C:\windows\system32\config\system
copy C:\windows\repair\software C:\windows\system32\config\software
copy C:\windows\repair\sam C:\windows\system32\config\sam
copy C:\windows\repair\security C:\windows\system32\config\security
copy C:\windows\repair\default C:\windows\system32\config\default
Now type Exit and watch your computer restart into Windows XP again. Be sure 
not to tell it to boot from the CD this time. But wait. That's not the way 
you had XP set up before this disaster struck! That's OK.
We're in a lifeboat right now -- this isn't your comfy cruise ship, not just 
yet. Hang in there.
        I'm going to show you how to restore your system to the way it was 
the moment before you told it to install that errant application, or 
whatever it was you did, so follow along and we'll go to part 2.
Part 2
Here's where you'll copy the saved registry files from their backed up 
location by using System Restore.
              This folder is not available in Recovery Console and is 
normally not visible -- Microsoft is protecting you from yourself by hiding 
it from you and locking it away from you. But we have the keys.
Before you start this procedure, you'll need to change several settings to 
make that folder visible:
1. Start Windows Explorer.
2. On the Tools menu, click Folder options.
3. Click the View tab.
             4. Under Hidden files and folders, click to select Show hidden 
files and folders, and then click to clear the "Hide protected operating 
system files (Recommended)" check box.
5. Click Yes when the dialog box is displayed that confirms that you want to 
display these files.
6. Double-click the drive where you installed Windows XP to get a list of 
the folders. It's important to click the correct drive.
              7. Open the System Volume Information folder. This folder 
appears dimmed because it is set as a super-hidden folder. If you're using 
the FAT32 file system, this will be easy.
          If you're using NTFS, it won't let you open the folder, but here's 
how to get around that: Right-click on that system volume information folder 
and select Sharing and Security.
         Then click the Security tab. (No security tab? Skip two 
paragraphs.) Click Add, and then in the box that's labelled "Enter the 
object names to select," type the name of the user that's at the top of the 
Start menu -- that's probably you.
 [Damn it, why do they say object names when it's people's names? I guess 
that's Microsoft for you.]
             Anyway, make sure you type the name the way it's listed there 
on the Start Menu. I made the mistake of typing my first name only and it 
wouldn't let me in.
             Type first and last name if that's how it's written on the top 
of the Start menu. After you've typed that in, click OK a couple of times 
and finally that monster will let you in.
           But what if you don't see a Security tab? Try this: Click to 
select the checkboxes in the "Network sharing and security" area -- one is 
labelled "Share this folder on the network" and the other is labelled "Allow 
network users to change my files."
        Change the share name to something short, like sysinfo. Then it'll 
let you in. After you're done with this entire rescue operation, you might 
want to go back and change these back to the way they were before, for 
maximum security.
           OK. Now here you are, in the inner sanctum where only the high 
priests go. Be not afraid, all ye who enter here. As Microsoft so eloquently 
puts it:
NOTE : This folder contains one or more _restore {GUID} folders such as 
"_restore{87BD3667-3246-476B-923F-F86E30B3E7F8}".
            8. Open a folder that was not created at the current time. You 
may have to click Details on the View menu to see when these folders were 
created. There may be one or more folders starting with "RP x under this 
folder. These are restore points.
             9. Open one of these folders to locate a Snapshot subfolder; 
the following path is an example of a folder path to the Snapshot folder:
C:\System Volume 
Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}RP1Snapshot
       From the Snapshot folder, copy the following files to the 
C:\Windows\Tmp folder (you can use your mouse, you're in Windows now, 
remember?):
_registry_user_.default
_registry_machine_security
_registry_machine_software
_registry_machine_system
_registry_machine_sam
Anyway, you're still not done. Don't worry, the magic is about to begin. 
Believe me, if you do this in front of your friends, they'll start thinking 
you're some kind of god. So, heavenly father, get ready to dazzle 'em.
           Now it's time to place those files you just made visible to the 
Recovery Console where they belong. And to do that, we need to get back into 
the Recovery Console.
           So, make sure your CD is in the drive, and restart Windows, this 
time hitting any key when it tells you to do that if you want to boot from 
CD. Yes, you want to boot from CD, so you can launch your old cryptic pal, 
the Recovery Console.
           Type R after it goes through that file-reading routine that looks 
like an install but isn't. Then you're back into our dark-suited friend with 
its ominous command line. It's kinda like going into the basement to fix 
some broken pipe or something.
 But we're not scared. The command line is our flashlight and friend. Here 
we go:
Part 3
         In part three, you delete the existing registry files, and then 
copy the System Restore Registry files to the C:\Windows\System32\Config 
folder:
From within Recovery Console, type the following commands:
Del c:\windows\system32\config\sam
Del c:\windows\system32\config\security
Del c:\windows\system32\config\software
Del c:\windows\system32\config\default
Del c:\windows\system32\config\system
copy c:\windows\tmp\_registry_machine_software 
c:\windows\system32\config\software
copy c:\windows\tmp\_registry_machine_system 
c:\windows\system32\config\system
copy c:\windows\tmp\_registry_machine_sam c:\windows\system32\config\sam
copy c:\windows\tmp\_registry_machine_security 
c:\windows\system32\config\security
           copy c:\windows\tmp\_registry_user_.default 
c:\windows\system32\config\default Now. You're done! Type exit and your 
computer will reboot into whichever restore file you chose.
           But wait. If it's not the right one, that's OK, you can now go 
into your System Restore area and pick a different restore point if you 
want. There's a whole calendar full of them in there.
           I bet you didn't know that Windows XP is watching just about 
every move you make, taking notes all the while. It can restore about any 
state you had on that machine.
    And the best part is, even when it's doing all that, it's still 10% 
faster than Windows 2000 according to our extensive tests here at the 
Midwest Test Facility. Here's how to get into that restore area if you're 
not happy with the current restore point:
1. Click Start, then click All Programs.
2. Click Accessories, and then click System Tools.
3. Click System Restore, and then click Restore to a previous Restore Point.
       Sheesh, before this I hated the command line.
            Many of you probably still do.
            But when it saves your butt like this, you have to feel 
grateful. I should send out a badge of courage for   all you intrepid souls 
who       followed me into these dark gallows, the basement of Windows XP.
          I hope this routine was successful in bringing your computer back 
to life. I know how it feels to have your computer down for the count.

 Come posso risolvere?
Inserisci il cd originale di Windows XP e fallo partire all'avvio del
computer come se dovessi fare una nuova installazione.
Entra nella console di ripristino e scrivi "chkdsk /R" (senza virgolette) e
dai invio.
Al termine della procedura di scansione riavvia il computer e vedi se parte
in modalità normale.
Qualora il sistema continuasse a bloccarsi in fase di avvio,entra di nuovo
nella console di ripristino e scrivi il comando "listsvc" e dai invio.
Verrà visualizzata una lista di tutti i drivers ed i servizi che il sistema
carica all'avvio,qui puoi vedere un'immagine di esempio della lista:
http://tinyurl.com/yyxeco
Cerca di individuare il driver o servizio inerente al programma che hai
installato e disabilitalo scrivendo il comando "Disable nome del driver".
In questo modo il sistema dovrebbe ripartire.

Console di ripristino:

Scandisk e chdisk li ho già provati. Schermate blu non ce ne sono.
Cercherò di essere più preciso, si passa il post del bios si avvia il
sistema e mentre viene caricato windows e si vede la schermata con il
logo tutto si riavvia e si ritorna alla primissima schermata.
Ora provo a vedere che succede con il cd che mi è stato consigliato.
Grazie ancora, ciao ciao.

Ciao a tutti, grazie per gli aiuti credo di aver identificato il
problema.
In pratica ho provato a fare dei test sulla ram, un banco alla volta
con memtest 1.65. Nel mio computer avevo 1.5gb di ram, un modulo da
1gb e due da 256mb.
Se lascio solo il modulo da 1gb sul primo slot libero sulla scheda
madre, tutto parte tranquillamente. Appena aggiungo uno dei due moduli
di ram tutto si blocca come descritto in precedenza.
I test davano errori su quei due moduli di ram così ho provato ad
inserire, insieme al modulo da 1gb un altro modulo da 1gb preso da un
altro computer (il modulo è perfettamente integro).
Appena ho aggiunto il nuovo modulo ho riavuto nuovamente gli stessi
problemi.
A questo punto penso sia un problema sugli slot per la ram della
scheda madre, perchè i moduli di ram difettosi su altri computer
funzionano senza problemi.
La scheda madre è una abit nf7 su cui è montato un athlon xp 2800. Si
può fare qualcosa per recuperare gli altri due slot per ram o no?
Grazie a tutti, ciao ciao.
