When I switch on my computer Windows XP keeps loading and loading time after time but doesn't start. I have tried loading in LAST KNOWN GOOD CONFIGURATION also in SAFE MODE - but nothing loads it just goes thru the start proceedure again and again. I then tried DISABLE AUTOMATIC RESTART ON SYSTEM FAILURE and got the following message - "A problem has been detected and windows has been shut down to prevent damage to your computer. BAD_POOL_CALLER etc etc Technical information xxx Stop: (0x 000000C2 (0x00000043, 0x0xDD661000, 0x00000000, 0x00000000) Beginning dumping of physical memory Physical memory dump complete Can anyone help. Many thanks for looking at this Phyllis
Hi, Sorry to hear of the problem with your computer.
Sometimes these sort of errors are not easy to fix by correspondence over long distances, but we will do our best to help.
1 The error code is usually associated with a bad driver, or piece of software that has recently been installed.

2 Its possible that using the Windows XP System Restore facility to "roll back" in time your computer to when it was working OK may do the trick for you.( But first we need to get your machine to boot up so we can try to repair it!

3 Before we suggest any steps to you to repair your machine, it's important that you locate your back up/copy/archive of all your important stuff and check using a known working machine that it is 100% up to date, accurate, and reproducible…if you have any thing at all important (stuff that you would not like to lose) that is not safely copied to removable media then take the opportunity now to remedy it……a reasonable way to do this is to boot from a Live Linux CD ( Linux Puppy is a fairly small download (around 100MB) and use this to access your hard drive and copy off important stuff to external media (USB external hard drives are a useful thing to use) You may need to amend the boot priority order in the BIOS to boot first from CD…..post back if you need further help on how to do any of the above.

4 Once your important stuff is safely copied to remove media we can turn to trying to fix your computer, so we will start with Using a System Restore Point created before the issue started here's how to do this:

Once the System Restore has completed your machine will reboot and hopefully Windows will be available….if its not then:

5 a Repair Installation of Windows is probably well worth considering. (This should be "non destructive" and leave your data intact.(but there are no absolute guarantees, hence the importance of a good back up)

6 If this does not work and you still cannot boot into Windows, then I would be inclined to re-image using a disc image created before the problems stated. You will need a bootable CD for this, so try to locate it now (if you made one)

7 If you didn't make a disc image, then maybe its time to consider performing a full (destructive) reinstallation of Windows…note this will clear all the data and other files from your machine.

8 Some computers have a Recovery Partition that will perform this task for you fairly quickly, and some manufacturers ship their machines with a Recovery disc(s)…but please note both these will clear everything from your computer ( hence the importance of having a good back up/ disc image kept safe on removable media.
Good luck and post back if you have any questions… (the make and model number of your computer is always useful to us in helping us to help you)

Thanks Paws Point 3 below is not clear to me how I go about saving my important stuff. Can you give me an idiot guide to "booting from a Live Linus CD" I have no idea what to do or how to get this to access my hard drive. Many thanks again for taking the time to help. I will not be able to get back to you before Monday as I am corresponding from a computer in my office.

Hi Phyllis, I'll do my best!
You will only need to use Linux Puppy if for any reason your backup is deficient in any way….. I often emphasize the importance of checking tha back up is up to date, as some folks have never backed up their important stuff at all. It's easier to copy stuff off from within Windows, but if Windows won't boot up then using Linux Puppy is pretty effective:

The Linux Puppy Live distro is a very useful tool, that is in constant use in the workshop, but for a home user it has 3 main uses:

In explanation, Linux Puppy Live distro is a self contained operating system that runs in memory from a CD…..or even a thumb drive if you are crafty (That's what the "Live" bit means), so it doesn't need Windows at all, IE no need for a working copy of Windows XP, Vista, 7 or any earlier version of Windows. It is in effect an alternative to Windows and also has the advantage of being free (quite legally). Because Windows is fitted to the majority of PC's, folks are often unaware that there are different operating systems available….one of the advantages of Linux is that it is issued free under a general licence unlike some other operating systems (like Windows) that are charged for by their developers.

1 If a machine won’t boot, then we need to know first off, if its a hardware problem. or an operating system (Windows) problem…..if it is hardware then there's no need for us to spend time trying to alter Windows settings……. so first we try to boot from the Linux Live Puppy disc (altering the boot priority in the BIOS if necessary to facilitate this) if the machine works perfectly under Linux then we can be reasonably sure that the hardware is OK and so we start looking at the Windows operating system to try and identify the problem so that we can fix it.

2 If a machine won't boot into Windows even in safe mode, It can be a very worrying time.
For Example
When the machine won't boot up, no matter what you do and you realise that all your important stuff, (music, photos, work, address books and contact lists, emails, downloaded programs and all your Microsoft Word docs, Excel spreadsheets, data bases PowerPoint presentations and all the rest perhaps including the only draft of the book you have spent the last 3 years researching and writing or your PHd thesis) have all disappeared…………
then we can try to boot into Linux Live Puppy, access the hard drive (Live Puppy does this automatically) and copy off the data to safe external media (its surprising that despite everything that has been written about the need for back ups, so few folks actually have an up to date accurate and reproducible back up of all their important stuff kept safe on removable media……

3 Its a super way of becoming familiar with a different operating system…….without making any changes to the hard drive..that might affect Windows…its a way of learning and experimenting and finding out information in a no risk, or at least low risk way.

There's lots of other things, but hopefully, the above will give you the idea.

Linux Puppy backup Introduction: Back up when you can't boot into Windows:
A.) Please take the opportunity now to bring your back up/archive/copy of all your important stuff 100% up to date, check that it's accurate, reproducible and held securely on removable media (not your hard drive)……
the idea here is to ensure that all your important data, files, spreadsheets, work, music, emails, log in details, user names, address book, drivers, letters, invoices, videos etc….in fact everything that is important to you (stuff that you would not like to permanently lose) is kept safe on external media. I recommend the use of a USB external hard drive for this.
Whilst you are doing this, collect together all your application installation discs (or downloaded installation executables) serial numbers, product licence keys (including the one for Windows itself and the Microsoft Windows installation disc and or Manufacturer's Restore and Driver/utilities discs.
If you have made a "disc image" using Paragon, Acronis, Ghost or one of the free disc imaging alternatives then keep this image safe also on removable media, verify it for correctness and reproducibility and ensure you have made a bootable CD/DVD for use in the event that Windows will not start.

Now, here's the detailed instructions on how to do it. You will need access to a working computer for this.
B.) Download Linux Puppy from here:
Linux Puppy
Its a download of only around 100MB, so a broadband connection is advisable for the download… Puppy is an alternative operating system….. it does not need Windows to run, and the licence to use it is free of charge and comes included automatically. It is different in its interface from Windows, but sufficiently intuitive for most folks to use it successfully without problem.
C.) Burn the iso (that you have downloaded) to CD ROM as an "image"…it must be as an image, a copy will not work!……..Imgburn is good for this, available from here:
http://www.imgburn.com/index.php?act=download
D.) Switch on your "unco-operative" computer and Set Bios to Boot from CD as first priority…on most Dells it's F2 to enter the Bios (set up) otherwise try F12, Esc or Del.
NOTE you will need to press the appropriate key (to enter the Bios) immediately after power on.
Your hard drive should be next in priority followed by USB/network if the settings provide these options. Remember to save your altered settings in the Bios before exiting
E.) With your external back up media plugged in to a USB port I.E. External USB hard drive, flash drive etc and the Linux Puppy CD ROM inserted into the CD drive, close down your machine and:
F.) Boot from the CD, you may get a message to "press any key to continue booting from CD" so allow this, Now follow the on-screen Linux Puppy prompts as to location, keyboard, video etc., and will allow you access to your Hard drive so you can copy off to your external media anything you need. You will soon get used to Puppy and you'll find that you will be able to use the Internet and do most things that you want to do. However as you need to back up your files, I suggest you concentrate on copying off your important stuff first.
G) With your external hard drive or memory stick in the computer (click on) open a window for your hard drive and the external drive and simply drag and drop your folders and files across……..tip……. only drag one folder at a time (otherwise Puppy can get "indigestion") so when you have dragged your "My Documents" folder across wait until its finished copying before dragging the next folder across.
Good luck

Thanks paws I have set BIOS to Boot from CD as first priority. You have said that the hard drive should be next in priorty followed by USB/Network. I cannot see these options so can you tell me what I should place as 2 or 3 in the booting order from the following list I have available:- Floppy LS120 IDEO SCEI IDE1 IDE2 IDE3 ZIP100 USB-FDD USB-ZIP USB-CDROM USB-HDD LAN Disabled Hope to hear from you soon Phyllis
Paws I tried the CD with Linux Puppy with the following setting 1st Boot Device CDROM 2nd Boot Device IDEO 3rd Boot Device IDE1 Boot from other Device Yes Unfortunately this did not work. Although the black screen showed Loading from CD at the top the Windows screen reappeared and kept on trying to load Windows over and over again. Help Phyllis
Hi Phyllis, That looks like the iso wasn't burnt as an image (using ImgBurn) If that is so then try to burn it again ( using a new CD) using Imgburn and see if this does the trick… Regards paws
Thanks to both Paws and Lee I have downloaded files to USB (although I don't know if I have downloaded my e-mails from Microsoft Outlook - couldn''t find them) I have tried to repair windows by downloading the file you suggected I download containing the proper utilities. Unfortunately when i get to the recovery consul command prompt - when I try to enter the cd \ command - it only allows me to enter one letter. This is in response to the question Which windows installation would you like to log onto. (To cancel, press ENTER) Can anyone advise what I can do next. Phyllis
Hi What next I say!!! When I try to enter the required prompts in recovery when I type in ~ it comes up as | also when I type in # it would come up as \ In other words it is showing another keys symbol when I type it in. the recovery consul does not accept my prompt - wrong syntax i have tried onother keyboard and the result is the same. Any ideas Phyllis
Hi Phyllis, I'm slightly confused… Did you copy across to removable media all your important stuff ? (anything on your computer that you don't want to lose?) Your Microsoft Office Outlook files will be in a .pst file so try and find that and copy it to reomovable media. If so then you have a number of choices as to the most timely and cost effective method of repair If you can get into the Recovery Console then try running chkdsk /r from the DOS prompt. If you are still having keyboard errors then try doing a Repair installation….. ( That should be non destructive of data) If you cant do that then the next best choice is reimaging from a disc image made when your machine was running fast and sweet…..(made with a disc imaging application like for example Paragon, or Ghost or Acronis etc of one of the free disc imaging applications. If you don't have agood disc image then try the manufacturer's restore discs…they will set your computer back to its "Factory State" Ie the same as it was when it left the factory….NOTE this IS destructive of your data hence the need for a good back up…. If still no joy then its a format and restore using your Windows XP installation discs. Good luck Regards paws
