Bad Checksum Error

[Guest]

Prior to our time change recently, I started up my home computer to make sure
all the XP updates were installed (I don't very often turn it on, so I knew I
would have some updates).

Not very far into the download, I got a blue screen with this error message:

STOP: C0000221 {BAD IMAGE CHECKSUM} The image olesvr32.dll is possibly
corrupt. The header checksum does not match the computed checksum.

I have searched the MS Knowledge Base and have found some ideas how to fix
it, but my problem is I can't boot into safe mode, nor can I use my recovery
CD to get into XP. The CD drive has power, so I can open it to put a CD in,
but the computer won't read it or boot from it.

I cannot get to a DOS prompt, either. I have no idea what to do next.

All suggestions are much appreciated. Thank you.

Have you set your System CMOS/BIOS settings to boot from the CD? You have
to tell the machine via that route to boot from the CD drive if it sees a CD
in it.
Then, once that is set, when you do a restart, you should see something
like "Press a key to boot from CD... " for a few seconds. If you don't
press a key, you'll boot normally instead of from the CD. Press a key and
the boot should start from the CD.

The "DOS" prompt should be available by typing Start; Run and typing CMD
into the box, and clicking OK. Or, Start; Programs; Accessories; Command
Prompt. It's not DOS as you knew it back in win98, etc.; it's called a
Command Prompt now and is considerably enhanced and different from the old
DOS days, though most of the same commands still work.

Thank you, Pop, that works now, but I have no way to retrieve my data before
reinstalling XP. I'm trying Bart PC in order to get to my files, but this
software is not recognizing my USB drive. I've managed to copy some files to
a floppy, but at this rate, it's going to take me a year.

Any ideas how I can get my files before I reinstall? Thanks!!

I don't understand; what "works now"? Floppies just aren't going to work
I'm afraid.

Assuming the CD is working now, you should be able to save your files to
CDs, no?
Assuming most of your data is small enough to fit on CD, that should
work; just copy or move the files to the CDs. DVDs would be better if you
have a DVD writer.
Or just your external USB drive? Dunno what size it is or any other
details, so not much to go on here. Can you access the external drive with,
say, windows Explorer?
Did the external drive need to be installed originaly? Perhaps it needs
to be reinstalled again? I don't use BartPC so have nothing there.
Personally I'd use ntbackup.exe to back up the files, but whatever works is
what you should use.

Let us know.

I'm sorry, I wasn't clear at all. I made the BIOS change you and now my CD
is bootable. I used the XP reinstallation disk and was able to boot into the
reinstall program. However, everything I have read indicates that my data
should be removed before I reinstall.

Unfortunately, I cannot get into Windows, nor can I get to a DOS prompt, so
I have no way to remove my data before reinstalling.

I did use a program called Bart PC that simulates an old Windows File
Manager that I thought I could use to copy my data to my USB drive. But for
some reason it does not recognize my USB, and using this program I am unable
to copy to CD. I have begun transferring files to a floppy disk, but this is
painstakingly slow.

So if I can't get into Windows and can't get a DOS prompt, how can I get my
data?

Thanks again,
Kim

You might be able to copy that file from a good computer in C:\windows\system32
or enter the bios on startup and set it to boot from the cd drive.
