Please help!  I am currently running a home-built system with 4 hard drives, one of which is new.  I have installed Windows XP Home on the new disk in an attempt to migrate my primary drive to the new one.  It has run smoothly without problems for a number of days, through my normal install process.  However, following minor overclocking to my dual-core AMD Opteron CPU and voltage changes in the BIOS to the system fans, the computer crashed on multiple occasions as I determined a stable level of operation.  The crashes often took place while I was playing Grand Theft Auto: San Andreas, a system intensive PC game.  Following the latest crash, I am no longer able to log onto Windows.  I am a seasoned PC builder and have not come across these symptoms before.


From the Windows Logon screen (Welcome screen disabled), my administrative user name, Zimtok5, appears in the user box, and the password cursor is blinking in the password box.  However, despite keyboard operation in the CMOS boot screen, neither a USB nor Serial keyboard will respond to entering text into the password box.  Hence, I am unable to log onto my one and only profile (an administrative account with a password).   Also noteworthy; the light on my USB mouse is powered as the system is loading, but this dies once the Windows logon screen comes about.  Also, attempting to boot the machine from my Windows XP Home CD will not work, as the keyboard will not interrupt the Windows boot sequence when I am prompted to Press any key to boot from CD&..

To diagnose this problem, I launched Windows from my old install on my old hard drive by swapping the SATA cable targets around on the motherboard.  Through Windows Explorer, I was able to look at the data included on the new drive.  I was able to view all the Windows systems files and everything looked in working order with one exception: my account profile.  The folder E:\\Documents and Settings\Zimtok5 (my administrative user account on the 'new' drive) was inaccessible when accessed from Windows run on my old hard drive.  Is there a possibility that this profile has become corrupted from a crash and if so, how can I retrieve the data within this folder?  I have searched through the Microsoft Help and Support website for an article with similar problems without avail.

Any assistance would be greatly appreciated.


I have spent the last few days since I wrote this help document trying to solve this same problem.  I have tried running through Microsoft Support article, "How to recover from a corrupted registry that prevents Windows XP from starting" (KB ID no. 307545).  I was able to use a PS/2 keyboard to get into my Recovery Console, as guided by the Support document.  From there, I proceeded to copy E:\windows\system32\config\system, ...\software, ...\sam, ...\security, and ...\default files to a 'tmp' folder and delete the original instances, replacing them with those from the windows\repair folder.  Restarting the computer, I was able to see that the Administrator and Owner login 'buttons' on the Windows XP Welcome screen, which I had previously had disabled for the Win2000-esque logon screen.  My 'Zimtok5' administrative user logon button has disappeared.  However, at this point no combination of attached peripherals works to operate Windows.  No response from any of the following: 2 x USB mouse, 1 x USB keyboard, 1 x PS/2 mouse, 1 x PS/2 keyboard.

By booting into Safe Mode by pressing F8 after POST, the machine logs into Windows, to a low-res background, 3 of my game icons appear on the desktop, but none of the folders, etc which were previously there.  None of my mice/keyboards work and the hardware manager pops up, apparently recognizing each device individually, but the hardware driver manager (name?) pops up and at this point, I am stuck.

Alternatively, by booting to my old local disk on my C:\ drive, I am able to view and modify all the Windows folder contents, etc. on my E:\ drive Windows install.  However, my administrative user account folder is inaccessible.  I have tried to run through various Microsoft Support documents, to no avail.  [example: "Folder is not accessible.  Access is denied." (KB ID no. 810881)]  Seemingly, because I am running Windows XP Home, I am unable to disable Simple File Sharing to view the Security tab for any of my drives, and thus I am unable to reset the permissions to the folders I need access to.  I have tried entering into Windows from my sole administrative account, but I am unable to see this 'mythical' Security tab, spoken about by Microsoft Support articles (written for WinXP Pro, it seems).

If any genius can help me wriggle out of this complex scenario, I would be enormously grateful!!!

Best Regards,
Brad (Zimtok5)
