stopped working

my inspiron 1521 just stopped working
the message I get when trying to boot up is
STOP: c0000221 {Bad Image Checksum}
The image comdlg32.dll is possibly corrupt. The header checksum does not match the computed checksum.

 

That error indicates the needed file is corrupted.

you can try manually copying the file into the windows directory or try to repair the windows files by booting up using the Windows installation disk and choose the Repair option.

 

Hi,
My name is Rajesh and I represents DELL in Social Media Forum.

This issue may occur if any of the following conditions exist:
• A damaged file exists in the folder in which Windows is installed, and this file is not overwritten during Setup. For example, if you receive the error message that references the User32.dll file, the User32.dll file may be damaged.
• One or more of the random access memory (RAM) modules that are installed in your computer is faulty, or the RAM configuration is incompatible.

To resolve this behavior, use one of the following methods.

Extract a new copy of the User32.dll file from the Windows XP CD to the drive:\Windows\System32 folder on your hard disk, where drive is the drive on which Windows is installed:
1. Insert a Microsoft Windows Millennium Edition (Me) or Microsoft Windows 98 Startup disk into your computer, and then restart the computer.
When the Windows Startup menu appears, use the ARROW keys to select Start Computer with CD-ROM Support, and then press ENTER.
2. Make a note of the drive letter of your CD-ROM drive.
3. Rename the User32.dll file to User32.old. To do so, type the following lines at the command prompt, pressing ENTER after each line, where Drive is the drive on which Windows is installed:
Drive:
cd windows\system32
ren user32.dll user32.old
4. Insert the Windows XP CD into your CD-ROM or DVD-ROM drive.
5. Extract a new copy of the User32.dll file from the Windows XP CD to the Windows\System32 folder on your hard disk. To do so, type the following lines at a command prompt, pressing ENTER after each line, where CDROMDrive is the drive letter of the CD-ROM or DVD-ROM drive that contains the Windows XP CD-ROM, and Drive is the drive on which Windows is installed:
a:
extract CDROMDrive:\i386\user32.dl_ Drive:\windows\system32\user32.dll
For example, if your CD-ROM is drive E and Windows is installed on drive C, type extract e:\i386\user32.dl_ c:\windows\system32\user32.dll, and then press ENTER.
6. Remove the Windows 98 or Windows Millennium Edition startup disk from your computer, and then restart the computer.

Or you can simlpy do a clean system reinstallation on the system with the operating system disc


Check for the RAM functionality . You can run the DELL diagnostic in f12 screen to run the pre boot system assessment and check for the functionality of the RAM
Hope this may fix your issue.
