BLUE SCREEN....PLEASE HELP ME! (STOP c0000221 {Bad Image Checksum}

[Guest]

PLEASE HELP ME!!!

I just installed a new DVD burner drive into my computer. It took me about
4-5 different configurations to figure out the right combination to get
everything working. I installed all the software that came with the DVD-R
drive. Now, when I restart my computer.....the screen is coming up blue
before my desktop normally loads with this message:

STOP c0000221 {Bad Image Checksum}
The image MSASN1.dll is possibly corrupt. The header checksum does not match
the computed checksum.

I restarted my computer about 10 times now, and nothing is working! I
don't know what to do or how to get past the screen. I hope I don't lose
ANYTHING on my computer! I have over 100GB of important files that I can't
lose! PLEASE HELP ME!

Hi Mike,

Firstly don't worry, you have not lost any of your important files. Chances
are, in fact, that you have not even lost any of your unimportant files. The
problem is you have a software and driver conflict that has to be resolved.

The first thing you should do is when the computer finishes its POST (Power
On Self Test), that is counts the memory and detects IDE drives, start
pressing F8 until you have the startup menu. Then select the option SAFE
MODE. Your system will boot into Windows with a minimum set of device
drivers and no software. You can then go into Control Panel and uninstall
the software that caused the conflict - probably the CD or DVD software.
Once that is done you should be able to boot back into Windows normally.

Once that is done I would recommend you download from the hardware vendor
the latest version of the software, and re-install.

By the way, I cannot repeat this often enough: When you have important data
on your computer, BACK IT UP - not to a different partition, but to a
different hard drive. Hard drives are cheap, and data is priceless!

Good luck to you!

I pressed F8 and chose SAFE MODE........another blue screen came up:

------------------------
A problem has been detected and Windows has been shut down to prevent damage
to your computer.

IRQL_NOT_LESS_OR_EQUAL

If this is the first time you've seen this Stop error screen, restart your
computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If
this is a new installation, ask your hardware or software manufacturer for
any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or
software. Disable BIOS memory options such as caching or shadowing. If you
need to use Safe Mode to remove or disable components, restart your computer,
press F8 to select Advanced Startup Options, and then select Safe Mode.

Technical information:

*** STOP: 0x0000000A (0xF8A51354, 0x000000FF, 0x00000001, 0x8050FD7F)

Okay, let's try this: When you press F8 is there an option that says 'Last
Known Good Configuration'? If so, selec this and then follow the same
procedure to remove the software.

In the worst case scenario Mike I want to put your mind at ease: WORST CASE,
you can plug the hard drive into another system as a slave and copy all of
your data over. Your files are intact, it is just your Windows install that
is a bit troubled.

In any event, At this point I would recommend also removing the device from
your computer and trying both Safe and Last Known Good. Let me know what
works!

Ok Mitch........still no luck......

I removed the DVD-R drive from my computer (the new one I just installed).
Then I restarted the computer and chose SAFE MODE and LAST KNOWN . Here are
the results:

SAFE MODE: long message about windows being shut down.
LAST KNOWN: STOP {Bad Image Checksum} message

Some info. that might help you to help me:
I had 2 CD drives in my computer. The top is a DVD/CD-ROM drive........the
bottom drive was a CD BURNING drive. The top drive was set to CS on the back
(I believe, and I was told by the installation manual for my new DVD-R drive
to change the top drive to MASTER.....so I did). Then I was told to set the
DVD-R drive (which replaced the CD Burning drive) to SLAVE....so I did that
to. SO I had the TOP as MASTER and the BOTTOM as SLAVE.

Before all this.......I had just put in the DVD-R drive without changing
anything, and it was set to MASTER I believe. I then installed the program
software for the DVD-R which is a bunch of NERO software which would enable
me to burn onto DVD's. Well, it turns out that my computer was only detecting
the new DVD-R drive.....and I couldn't figure out why. I checked in my manual
and finally figured out after calling a brother that I just had to take the
small thing out of the back and switch it to either MASTER or
SLAVE.......which is what the manual told me to do. So after the software had
already been installed, I restarted my computer.......and after switching the
drives to Master on TOP and Slave on the BOTTOM, both drives were showing up.
The wierd thing I noticed was that when I put a CD into the new DVD-R
drive......it wouldn't open anything. When I chose to EXPLORE.......it gave
me a window of the DESKTOP which really confused me. So, I reinstalled all
the NERO software.....and ironically it didn't tell me that it was already
installed. Also.......there's a program called INCD which was on my computer
which allows for you to drag and drop files onto CR-RW's. Well the new
software I received with my drive contained a more recent version
INCD4.....so I uninstalled the old INCD (which was very small.....I don't
even think it showed any MB on the uninstall screen).......and installed the
new INCD. So after both drives finally showing up when i went to MY
COMPUTER........and after the second time of installing the NERO
softwares.......and INCD4........I restarted my computer in the hopes that
everything would be great! Then came the BLUE SCREEN problem that I'm dealing
with now.

I don't know if now that I uninstalled the BOTTOM DRIVE (DVD-R).......if it
would help to change the TOP DRIVE (DVD/CD-ROM) back to CS or SLAVE from
MASTER. Also....should I reinstall the old drive???

Also....here are the options that I'm given after pushing f* when the
computer is starting:

-Safe Mode
-Safe Mode with Networking
-Safe Mode with Command Prompt

-Enable boot Logging
-Enable VGA mode
-Last Known Good Configuration (your most recent settings that worked)
-Directory Services Restore Mode (Windows domain controllers only)
-Debugging Mode

-Start Windows Normally
-Reboot
-Return to OS Choices Menu

I hope I haven't confused you with all the information. I hope we can
figure SOMETHING out!


Thanks,
Mike

Are you there Mitch?! I'm going crazy over here!

Okay, let's try this: When you press F8 is there an option that says 'Last
Known Good Configuration'? If so, selec this and then follow the same
procedure to remove the software.

In the worst case scenario Mike I want to put your mind at ease: WORST CASE,

Sorry... I left for a few hours for a prior commitment.

Try the solution that Will Denny proposed, and if it doesn't work, come back
and let me know.

Mitch,

That message from Will Denny was an informative link, but I found myself
looking in circles as to a solution to my problem. My Windows isn't even
starting, which is the main problem in all of this. I can't fix anything
unless I get into Windows, as you know. If I can't access Windows, then I
guess I have no choice but to buy a new drive and Windows XP software and
install it onto the new drive. Is it possible to use a Windows XP version my
brother purchased, or do I have to get my own? I'm just really bummed right
now. Not sure if you remember, but one of the blue screens (the long one)
said that Windows was shut down to prevent any damage. I think the problem
lies in figuring out how to reverse Windows being shut down. Thanks again for
your help.

-Mike
