Titolo: IL PC NON FUNZIONA PIU'

Ciao a tutti.
Spero che qualcuno possa aiutarmi.
Per sbaglio devo aver cancellato dei file vitali di windows 98; il pc non si
accende più perchè non riesce a trovare i componenti cancellati.
Potreste darmi delle "dritte" su come reinstallare ciò che manca usando il
cd di windows?
Grazie.

devi semplicemente riavviare il pc col disco di windows e selezionare
ripristino installazione, se non parte dal disco entra nel setup di
boot premendo canc, o f8, of2, ecc secondo il sw della tua sk madre.

 cd di windows?
Si cercati un tutorial sul web [1]  .. in pratica (vado a memoria)
devi sovrascrivere l'installazione di windows .. adesso non ricordo
piu cosa ti appare inserendo il cd d'installazione e lanciando
il setup ma dovrebbe essere comunque un avviso di windows
gia installato .. e ti verra proposto una nuova directory tipo
c:\Win000  >> tu se vuoi mantenere INTATTI i tuoi programmi ed
impostazioni ignora e metti c:\windows e fai partire l'installazione
Prendilo con le molle che come detto sto' andando a memoria

REINSTALL WIN9X
If some day your Windows 9x system goes "bonkers", stops working, or you
start getting frequent system errors, you might
want to consider reinstalling the OS. There are several ways you
can reinstall Windows 9x:
install "clean" on a freshly formatted drive/partition,
reinstall "new" in a different directory/folder,
reinstall ("refresh") over the old copy, in the same directory/folder.
The first two options above require the user to reinstall ALL apps/programs
from scratch (after installing the OS),
because that information is NOT retained in the newly created Registry.
If you opt for just a "refresh" reinstall (method 3 above), to eventually solve driver/hardware conflicts, replace
corrupted system files, or/and system configuration errors, then ALL
custom settings and app info/entries will be
preserved into the Registry.
This also redetects all hardware devices, and installs the appropriate
(i.e. your vendor provided) drivers, but it will NOT dispose of orphaned/corrupted
files in your C:\Windows and C:\Windows\System folders (presuming you
have used the default directory name for your previous Win9x installation).
To replace older/corrupted files, you need to apply theworkarounds detailed below.
Also, this restore procedure may or MAY NOT succeed, depending on too many factors, mainly hardware settings changes.
Therefore if this "refresh" install fails, you should be prepared to either do a "clean"
install (including reformatting your drive/partition), or make a FULL SYSTEM BACKUP beforehand, to be able to restore
the OS to its previous working
state.
The "full system backup" procedure requires that you have enough room on your drive/partition for another ENTIRE Win9x
copy. If you do, open Explorer, and copy your Windows folder to another destination (preferably another hard
disk/partition, for a quick restore). If you don't:
Pop in a new formatted floppy disk (1.4 MB). Create an Emergency
Recovery Diskette (ERD): Control Panel -> Add/Remove
Programs -> Startup Disk tab -> "Create disk..." button, but make sure
the DOS mode CD/DVD drivers are included on this
floppy, and that the proper entries are present in your startup files:
CONFIG.SYS + AUTOEXEC.BAT, to enable your CD/DVD
drive in native DOS. Example:
CONFIG.SYS line:
DEVICE=A:\CDROM.SYS /D:MYCDROM
AUTOEXEC.BAT line:
A:\MSCDEX /D:MYCDROM
Backup your VITAL System and Registry files: SYSTEM.DAT, USER.DAT,
SYSTEM.INI, WIN.INI, CONTROL.INI to a safe location.
Delete the following Registry keys (in this EXACT ORDER):
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class
HKEY_LOCAL_MACHINE\Enum
Now exit Windows to the native MS-DOS mode (described in "MS-DOS PROMPT",
 also in MYTIPS95.TXT [part of W95-11D.EXE].
Once at the plain DOS prompt, rename these Win9x System directories, by running:
MOVE/Y %winbootdir%\INF %winbootdir%\INFOLD
MOVE/Y %winbootdir%\SYSTEM\IOSUBSYS %winbootdir%\SYSTEM\IOSUBOLD
MOVE/Y %winbootdir%\SYSTEM\VMM32 %winbootdir%\SYSTEM\VMM32OLD
Reboot using the new bootup floppy, and reinstall Windows 9x into the SAME folder, answering "No" when prompted to
overwrite newer files, or "Yes" for older files.
After the OS install is successfully completed, reinstall ALL available Upgrades,
Patches, Fixes etc for your particular
Win9x release (ALL of which can be downloaded from the Microsoft web site).
Restart Windows and check if everything works properly.
In case of a buggy installation/system lockup, boot again to the native MS-DOS
prompt, and restore your old system
(using same folder names as in the example above):
DELTREE/Y %winbootdir%\INF
DELTREE/Y %winbootdir%\SYSTEM\IOSUBSYS
DELTREE/Y %winbootdir%\SYSTEM\VMM32
MOVE/Y %winbootdir%\INFOLD %winbootdir%\INF
MOVE/Y %winbootdir%\SYSTEM\IOSUBOLD %winbootdir%\SYSTEM\IOSUBSYS
MOVE/Y %winbootdir%\SYSTEM\VMM32OLD %winbootdir%\SYSTEM\VMM32
ATTRIB -H -R -S %winbootdir%\SYSTEM.DA*
ATTRIB -H -R -S %winbootdir%\USER.DA*
DEL %winbootdir%\SYSTEM.DA*
DEL %winbootdir%\USER.DA*
COPY/Y E:\BACKUPS\SYSTEM.DA* %winbootdir%
COPY/Y E:\BACKUPS\USER.DA* %winbootdir%
COPY/Y E:\BACKUPS\*.INI %winbootdir%
Type WIN and press Enter to start your old copy of Windows.
NOTE: To decrease OS installation time, you can (if your disk space allows) copy ALL contents of the \WIN95 (if
installing Win95/OSR2) or \WIN98 (if installing Win98/98 SE) folder on your Setup CD to a new directory on your hard
disk, you can (re)install, and even recover files later from.
UPDATE: "For many old "ini" type apps, reinstall can often be avoided in case #1 + #2, if the app is run from a portable
drive [or its own folder on C:\ in case #2] -- just save the "ini" file [and any other miscellaneous files belonging to
that app] in the Windows folder before the reinstall, then replace the "ini" after reinstall. Sometimes there may be an
old dll that gets lost.
Also make sure you have a copy of any older "proprietary" driver that doesn't have a recent substitute."
