The file is possibly corrupt. The file header checksum does not match the computed checksum.

Specs--

Model: Alienware M15X

OS: 64-bit Windows 7

RAM: 2x2GB Kingston RAM modules

(If you need to know anything else, let me know. I will do my best to find this information).

Hello! I am having a world of trouble trying to fix my computer. What happened was I installed an Alienware theme on my laptop, and while uninstalling it, my computer crashed. Now I have the message "The file is possibly corrupt. The file header checksum does not match the computed checksum," in white text on a black background when I try and boot into Windows 7. My guess is that my boot image is corrupt because the theme made its own boot image, and when the uninstall crashed, the file became corrupt. Since then, I have tried booting Ubuntu from a USB drive, same error. Booted with one stick of RAM each (they seem fine), same error. Made a System Repair disk using another 64-bit Windows 7 computer of mine (my computer doesn't seem to recognize the CD-R in the DVD drive), same error after some noises. I tried pressing F8 to  get to the Advanced Boot Options menu, but the same error text pops up. I can access my BIOS. 

All help appreciated. I am desperate to get this issue fixed.

    Hi Cameron ,

    Thank you for posting your issue on Microsoft Community Forums.

    As the computer does not seem to recognize the CD-R in the DVD drive probably boot order is set to Hard Disk Drive first. I would suggest you to change the boot priority to CD\DVD in BIOS and then try to perform startup repair.

    Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

    In order to make changes in the BIOS, I would suggest you to contact the computer manufacturer.

    Method 1:

    Unplug any external device connected to the computer except for keyboard and mouse and check if issue persists. 

    M ethod 2:

    Startup Repair is one of the recovery tools in the System Recovery Options menu. This set of tools is located on your computer's hard disk and on the Windows installation disc.

    Startup repair:

    Method 3:

    Also, if startup repair does not help, you can perform a system restore and check.

    Refer:

    What are the system recovery options in Windows 7?

    Note: When you perform System Restore to restore the computer to previous state, programs and updates you installed are removed.

    Hope this information is helpful.

    My issue (fix) was a single bad RAM module. I had 2 x 1GB Samsung, removed one and the fix was instantaneous. Hope this helps.

    This is NOT the fix and should not be marked as the answer. The problem is bad RAM., confirmed by several other posts that SHOULD be marked as the answer.

    Hi. I also encounter this problem after I wipe my video card. All what you need to do is to check all plug in the motherboard and clean it. Maybe dust enter a sensitive part of your PC. That's all.
