I have a Windows XP and have encountered a problem where I get the Blue Screen of Death. When I turn on my computer I get the microsoft windows screen and then nothing (just a black screen) for a few seconds and then it goes straight to the Blue screen. After that I can't do anything, it's completly locked. I can't even shut it off with the power button. I have to unplug it in order to turn it off. The error message is
STOP: c0000221 {Bad Image Checksum}
The image iertutil.dll is possibly corrupt.
The header checksum does not match the computed checksum.

Can anyone help! I have no idea what steps to take in order to fix the problem.

try this.....do these steps one at a time and try to boot into windows and only do the next step if the previous step did not fix it (nojoy)...
go here..download the following file: rc.iso....then run chkdsk /r from the rc.iso cd...

if you don't have a burning program that will burn .ISO files go here and get burncdcc ..a small FAST no frills iso burning program...

NOTE...do not put a blank cd in until burncdcc opens the tray for you
1. Start by clicking on BurnCDCC.exe
2. Browse to the ISO file you want to burn on cd/dvd ....in this case its rc.iso
3. Select the ISO file
4. click on Start

make sure in the bios the cd drive is the first boot device....put the cd in the cd drive..boot your computer....


when you boot from rc.iso you will get a blue screen and it will say setup is loading files...
then it will say its starting windows...
you will get to a screen that says ...do you want to install windows or 2nd choice it to repair windows..
press r to repair...you will get to a ...C:\>.......this is where you type in chkdsk /r

type in chkdsk /r press enter
note the single space before the /

While chkdsk is running, you will see a black dos box... Chkdsk will display the specific stage it is checking as well as the percentage of completion of the stage. You cannot do anything else on your computer while chkdsk is running. When chkdsk is finished, it will automatically reboot your computer.

NOTE this can take a long time to complete..it may even appear to hang or get stuck at a certain % for a couple of hours...then complete...it may even back up and go over the same area...this is normal...let it run...there are 5 stages
DO NOT TURN OFF YOUR COMPUTER WHILE RUNNING CHKDSK or you can have severe problems...
remove the rc.iso cd and reboot...if it does not boot into windows

boot from the cd again...
then type fixmbr press enter...reboot
no joy ....boot from the cd again...
type in fixboot press enter...reboot
nojoy...boot from the cd again...

Type in bootcfg /scan and press enter

if it says total identified window installs: 1

Type in bootcfg /rebuild and press Enter...

It will identify your XP installation...type Y once you see this prompt.

You will be prompted to enter the load identifier...type in Microsoft XP Home Edition or Microsoft XP Professional depending on whichever version you have...press enter

You will be prompted to enter the load options...type in /fastdetect and press Enter

Type in exit and press Enter

remove the cd and Reboot

still no joy...
get memtest 86here ...this will test your memory...let it run for at least 2 hours...if you get any errors then the ram is bad and will have to be replaced...no errors after 2 hours.......then its probably good and we can try other things..
it will run until you press the escape key
the how to is here..
