Did you attempt to boot the machine in "safe mode"? Booting in safe
mode allows booting with only a minimal set of supporting software such
as device drivers. From the Wiki article "safe mode"
=======================================================================
Microsoft Windows, Mac OS X and Linux distributions such as Ubuntu and
Linux Mint are examples of contemporary operating systems that implement
a safe mode (called "Safe Boot" in Mac OS X); as well as other complex
electronic devices.
An operating system in safe mode will have reduced functionality, but
the task of isolating problems is easier because many non-core
components are disabled. An installation that will only boot into its
safe mode typically has a major problem, such as disk corruption or the
installation of poorly configured software that prevents the operating
system from successfully booting into its normal operating mode.
Though it varies by operating system, typically safe mode loads as few
executable modules as possible and usually disables devices, except for
the minimum necessary to display information and accept input. Safe mode
can also take the form of a parallel "miniature" operating system that
has no configuration information shared with the normal operating
system. For example, on Microsoft Windows, the user can also choose to
boot to the Recovery Console, a small text-based troubleshooting mode
kept separate from the main operating system (and can also be accessed
by booting the install CD), or to various "safe mode" options that run
the dysfunctional OS, but with features such as video drivers, audio and
networking disabled.
Safe mode typically provides access to utility and diagnostic programs
so a user can troubleshoot what is preventing the operating system from
working normally. Safe mode is intended for maintenance, not
functionality, and provides minimal access to features.
Microsoft Windows' safe mode (for Vista/XP/2K/ME/98/95[citation needed])
is accessed by pressing the F8 key as the operating system boots.[1]
Also, in a multi-boot environment with multiple versions of Windows
installed side by side, the F8 key can be pressed at the OS selector
prompt to get to safe mode. However, under Windows 8 (released in 2012),
the traditional press-F8-for-safe-mode-options UI convention no longer
works, and either Shift-F8 or a special GUI-based workaround is
necessary.[1]
An equivalently minimal setting in Unix-like operating systems is
single-user mode, in which daemons and the X Window System are not
started, and only the root user can log in and which allows an
administrative account commonly known as "root" to have its password
reset without knowing what it is first.[2] On Mac OS versions 6, 7, 8
and 9, a similar mode is achieved by holding down the shift key while
booting, which starts the system without extensions. In Mac OS X holding
the shift key after powering up activates Safe Boot that has background
maintenance features (Besides the mode selection, it runs a file system
repair, and in Mac OS 10.4, it disables all fonts other than those in
/System/Library/Fonts, moves to the Trash all font caches normally
stored in /Library/Caches/com.apple.ATS/(uid)/, where (uid) is a user ID
number such as 501, and disables all startup items and any Login Items)
and can reset an administrative accounts' password.[3] In Windows, safe
mode with networking, one of the variations of safe mode, can be used to
troubleshoot network issues. In OS X, Safe Boot always includes networking.
======================================================================
If you can boot the machine in safe mode you may be able to get to
"System Restore". Each time the OS goes through some significant system
software update the OS sets a "restore point". That is, it makes copies
of the files to be updated in the event there is a problem caused by the
update itself. One can then return the system to that prior point.
There should be many restore points available to you. Your problem is
to find the most recent one that allows your system to boot. If there
is one (and there may not be) you may be able to get the system running
properly again without the complete restoration of system and apps. It's
also possible that, even if you're able to get the system running again,
further system updates to bring the system back to the level it should
be could reproduce the same problem. But that will likely happen anyhow
even if the system is restored from scratch.
If it was me I would not be doing what you're doing.
-----------------------------------------------------
Microsoft is dropping all further support of XP in a matter of weeks.
Even if you get it back up and running you're going to be faced with
problems of another kind. Don't go there. Bite the bullet and get a
Win 7 machine. Go for a refurb'd model to save some money (and for a
better chance of finding a Win 7 vs Win 8 machine). I will be replacing
my wife's Dell XP laptop very soon with a Win 7 laptop for the same
reason. The old Dell laptop will be re-purposed as a Linux machine
(maybe Puppy Linux) and will be used solely for banking and investment
transactions. It will likely only ever know about 4 or 5 websites.
Note that browser infections from infected websites are now a much more
likely cause of security breaches than viruses infecting the OS. That
goes for Apple and Linux too.
ps: If you can get the old machine to boot in safe mode or with the Win
XP install disk (or read the disk by attaching to another computer) you
might want to take an inventory of applications installed. You've
likely forgotten about many of them but not necessarily because they're
forgettable. Compare your set of install disks with those things you
actually use.
