HELP! XP STOP error !

[Graham]

My wifes computer has a serious problem! This developed the other day when
the computer froze and she went to reboot. Computer is generic model with
Asus A7A266 Socket A motherboard. It has a single 512MB DDR DIMM for memory.

What happens, is that it goes through the boot process, the Windows XP
splash screen appears but then we get a blue STOP screen that says:

STOP C0000221 {bad image checksum } The image CRYPTUI.DLL is possibly
corrupt. The header checksum does not match the computer checksum.

The computer then reboots in an endless loop.

I have tried using F8 to start up in safe mode, but this does not work - it
fails at same point. None of the options on the F8 manu achieve anything.

I checked the BIOS and it reports that 512MB of memory are there. Not sure
if it tests the memory.

XP is on an Ugrade CD. The comuter belonged to a relative, and we don't have
a boot disk. I do have boot floppies (probably W98SE) and a W2K Pro boot CD,
but have not tried any of these. Also have my original windows version on
floppy - Windows for Workgroups - Upgraded many times since then!

Question:

How do I get access to the hard drive and try and fix this problem!

Thanks

Graham

if you had the install cd you could perform a repair install, however since
you appear to be lacking in repair skills, I suggest you take it to a
reputable repair shop and have them fix it. don't make it worse by trying to
do things you don't have the skills to do.

Hmm - This poster seems to be the one lacking in skills. Persoanl skills at
least. No useful information provided and without knowing my background
insults me.

Hopefully I will receive a response from someone who CAN help with this
problem.

If you look this up here http://aumha.org/a/stop.htm, you get:

0xC0000221: STATUS_IMAGE_CHECKSUM_MISMATCH

Indicates driver problems, system file problems, disk corruption problems
(such as a damaged pagefile), or faulty memory hardware.

If you changed nothing - such as installing drivers - I suspect hardware
failure. The BIOS has no ability to check memory. I would start the
hardware diagnostics with the hard drive, then the memory. If this is an
elderly machine (as I suspect it is), the motherboard could have died also.
Nothing lasts forever.

While I don't think boot disks will help you in this situation since
software solutions won't help with hardware problems, a boot disk isn't
needed. The XP CD is bootable and even though it is an upgrade version can
do repairs. During a clean install onto a bare metal drive an XP upgrade
version will require you to put in qualifying media (Win9x/ME install
disk). But as I said, I doubt that is germane in your case.

Thanks for the useful reply.

When I first tried to boot from upgrade CD, it said something like No
emulation, but after a few tries and hitting "any button" a little sooner,
it did boot and went to Setup similar to what I have used on W2K.

So, now I am in recovery console and have got to C:/windows.

Now, do I have to manually extract CRYPTUI.DLL ?

I realise that we may have a hardware problem, but I suppose there is no
harm in attempting the software fix first?

[shrugs shoulders] It isn't what I would have tried first, but do what you
like. If you want to extract that .dll and copy it to Windows/System32 on
the hard drive, go for it. If it fixes your issue, great.

Malke,

Actually, I did FIRST open the case and made sure fans were running. Also
checked the MB hardware monitor and everything looked OK. I also removed
the RAM and made sure contacts were clean. Unfortunately, I don't have a
replacement to try (it's just a single and a different type from my own
machine). I will download and try the memory test from a floppy.

Thanks for you help.

In the end, if it IS a hardware problem, all I may want to do, is transfer
my wife's data (just a few files that she did not back up) to another
computer. But, if I can get whole machine running, I could transfer more
easily to an external USB drive which she could then access from our laptop.

I ran the memory test and received many errors! I inspected the MB, and
found a dark spot on an unused memory slot that looked like it might have
been burned - arcing? I cleaned it up. I also cleaned the DIMM contacts and
re-installed. Ran test again for long time and no errors!

Tried extracting the .dll win said might be corrupt but no change - still
stops at same point with blue screen.

Did a repair/install of XP. A few errors came up during install, but I do
now have computer up and running. I have at least one issue where I get a
message saying I need to re-install status.msi but it can't find the
installation package. Used Ctrl/Alt/Del to get rid of popup, but presume
this will come back again.

Read somewhere that this might be to do with HP printer. Will try
re-installing software. Also have DL Windoes Installer Cleanup - maybe that
will help?

During the repair/installation of XP several items produced errors and were
bypassed. If these are needed, will XP alert me or should I run something
like SFC to ensure everything is there?

Plan is to first backup drive and maybe find another MB or barebones box.
(Lost confidence in this MB).
