Cannot Boot Windows 7 "The header checksum does not match the computed checksum"

Q: Cannot Boot Windows 7 "The header checksum does not match the computed checksum"

A few days ago i recently got the "blue screen of death" for the very first time running windows 7..

Today i left my laptop on and went to sleep when i woke up it was trying to boot...
but was stuck on this error "The header checksum does not match the computed checksum"

I tried booting again but got the same error... i ran ubuntu live cd and tried to save my data files but it wont access my hard drive either... neither can i run recovery since it was also on a partition on the hard drive.

I have an HP Compaq CQ 70..
3GB Ram
Dual Core 2.0
originally came with vista i upgraded to win 7
Kindly help me recovering the data...

Preferred Solution: Cannot Boot Windows 7 "The header checksum does not match the computed checksum"

I recommend downloading and running DRP. It's a recovery tool that has been proven to recover files that most other programs have no luck with. I've even recovered files from freshly formatted or partitioned drives.

You can download it direct from this link http://goo.gl/v51TwD. (This link will automatically start a download of DRP that you can save to your computer.)

A: Cannot Boot Windows 7 "The header checksum does not match the computed checksum"

If you can't access w/Ubuntu, then it's likely that there's a problem with your hard drive.
Each use of the hard drive increases the chance that you won't recover anything. I'd strongly suggest looking into professional data recovery services - but be aware that they are very, very expensive!

When I don't mess with the BIOS, I get the error message, "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key_" If I change HDD priority, I get, "The file is possibly corrupt. The file header checksum does not match the computed checksum."

Outcome: Reached boot selection screen. When OS selected, computer reboots. Screen blank, and computer unresponsive once it reaches the point where the Boot select screen would be.

A:[SOLVED] The file header checksum does not match the computed checksum

I think I know what the problem is. Hopefully, it's just my video card drivers screwing around. If that's the case, I'd just have to enter the OS in safe mode and delete the driver or just format the HDD. The problem is, it won't let me get to any such screen. Either the file is possibly corrupt, or it restarts.

Hi All,

I have been trying to install Windows 8 64 bit retail version on my PC for the last 6 hours without success . After the 1st part of the install where you choose the disk and partition to install to, then it copies files etc, the PC does a reboot, which is normal for this part of the install. However, I let the boot sequence continue without selecting dvd of course, then it tries to boot from the hard drive but I get an error.

The header checksum for this file doesnt match the computed checksum.
File: \Windows\system32\winload.efi
Error Code: 0xc0000221

My system was previously running Windows 7 Ultimate 64-bit for years without any problems. This is not an upgrade, I am starting from a clean slate with a fresh wiped drive with no partitions.

System specs:

AMD FX-8150

A:Header checksum of file doesnt match computed checksum

I replaced the Corsair 4x4GB (16GB) DDR3 1333mhz with a set of 2x4gb (8gb) DDR3 1333mhz Elixir ram from my other machine.
The 64-bit DVD booted all the way to the installer this time with bios in AHCI mode and CD/DVD set to Auto/Non-EFI (1st time it has ever worked). The installation went on without a hitch and rebooted fine without a checksum error and I am now using the install to post this message without problems.

The RAM was the problem all along, although worked fine on Win 7 for a couple of years. Just must not like this new system setup.

Thanks to Mike Barnes from tomshardware for the suggestion.

My Dell Inspiron 1521 laptop won't get past the Dell logo at startup, resulting in a black screen with the error message:

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

I shutdown my laptop normally last night and booted it up this morning and received this error message. I have not added or changed anything.

So far I've run the Windows hardware and memory diagnostic tool (F12) and there were no errors. I also tried to run the Windows Vista Repair/Reinstallation DVD that came with my laptop; however, none of the repair options will work and the Windows Vista install crashes each time.

Startup Repair provided the following problem signatures:



Can anyone suggest how I may begin to recover my laptop?

Help! Any technical assistance would greatly be appreciated.

Hi All
New build PC with Windows 7 32 bit, I keep on getting the following error message on start up after 30 mins of shut down ?. The file is possibly corrupt. The file header checksum does not match the computed checksum
Then I Alt+Ctrl+Del and the PC fires up ok.
The only peripherals connect are mouse, keyboard, and a Monitor, once booted up and running I have used the following to check things out:-
Windows Device Manager:- All items are working correctly with no exclamation or question mark warnings. I have update all drivers for all devices.
Windows computer maintenance: Again all items check OK and are working.
Intel Application Accelerator Raid:- again all Hard drives and their raid configurations all check out as OK.
If I restart the PC all is fine, if switch off the PC and restart within 10 to 20 mins all is OK. However if I switch off and re-start after 30 mins the checksum error message reappears.  
Any advice or assistance would be appreciatedThanks Zee Man

You need to boot from the CD. Enter BIOS setup and change boot sequence so that the CD/DVD drive is the first boot device. Then you can boot from the recovery CD.

Note, using a recovery CD will erase the entire hard disk and you will lose any documents, emails etc on the hard disk.

As of two days ago my computer will not load all the way to the desktop screen. Most of the time I turn off the computer and turn it back on again the computer loads a little and then turns itself off. I ran diagnostics and it said the computer failed the memory test. As of the last time I turned it back on the screen read ...

***Also, after opening the computer to find the RAMs - the fan is not clean. Obviously this is a problem, but could that be the initial cause instead of a bad RAM?

There's videos on how to take out the fan and clean it but they don't say if there is a risk.

Dell Inspiron 1525, Vista. AVG free, Adaware, Spybot S&D. Scans done weekly, no problem noted prior to this.

Daughter called me at work bent out of shape because she gets this on startup:

" The File is possibly corrupt. The file header checksum doses not match the
computer ed checksum..." All of her summer howework is on the HDD and she's no happy. She's been warned about not having backups, but she knows everything at her age...maybe this will get her attention. She says it flashes the Dell logo at start up and then goes to a black screen w/this message.
My search here kept coming up w/"IE cannot display this page...", so I thought I would start a new entry and hope somebody might have something to offer by the time I get home to look at it.

FWIW, this is a laptop on a wifi network. AVG on another computer on this network started giving a virus alert yesterday, (mentioning smitfraud), AVG scan found nothing, Panda online scan found nothing, and Spybot found nothing. That was my project for this weekend, but I guess it goes onto the back burner now. I do not know if there is a relationship between these two issues.

Any help anyone can provide will be greatly appreciated.

I have a Toshiba running Windows 7. The computer was having a lot of problems with opening files, getting on the internet, etc. It would boot up but then wouldn't do anything else. I have the Toshiba recovery media CDs which I have used in the past when the computer got a virus. I tried to use them again. This time it went through the process on CD1 but after pressing finish, it now gives an error when trying to boot.

The file may be corrupt. The file header checksum does not match the computer checksum.

I tried taking the CD out and booting up and got the same error. I tried putting the CD back in and redoing it but still get the same error. Are there any suggestions?

I have an older PC which I gave to my mum. It originally ran Vista, but I bought and installed Windows 7 Ultimate around 6 weeks ago after it had been inactive for 3/4 months. It was running great, but a couple of weeks ago it just started hanging for no real reason. Also, at startup it would say that the computer had not been shut down properly, even if it had. This was only when it was switched off at the wall, not after a restart or when the PC was left plugged in and switched on. She only uses the PC to look at You Tube and some webcams from her grandkids, and that's it, she's not very computer literate.

Initially, I left Windows repair to run overnight, but when I looked at it the following morning it was still in the repair screen, so I assume it had hung. I spoke to a local repair shop and they suggested I test the RAM, test the hard drive, and replace the CMOS battery. The RAM and hard drive checks went without any errors and after I replaced the battery the hanging stopped. I played with the computer all evening and shut it down as normal and switched it off at the wall. Next day I thought I would start it up just to check it and I was faced with a "cmos checksum error - defaults loaded" message. I thought that was strange, but maybe the battery was dead, so I swapped it over with one from my perfectly working desktop to try it out, and my desktop worked fine, but after shutting down my mum's one it had the same problem when power was p...

Had a lot of issues with the recent purchase of a used pc. When turned off for a while or power disconnect, would get....
" S/GPNV checksum bad "
" S/Date Time not set"

Replaced and/or reinstalled the following;

Operating System and battery with new. Had a dual-channel memory issue of 256mb x256mb channel 1, 512mb channel 2. Removed imbalanced 512mb to run at 256mb x 256mb only. Also had a USB wireless mouse I was using and replaced it with a ps/2. These are the variables I was told could cause the above notice. NO CMOS notice/warning being received. Having made these changes believed to be related, can't undeerstand why the "S/GPNV"warnings-

Any assistance would be appreciated-

A:Solved: On start-up receiving " S/GPNV Checksum Bad" message

Start by setting the correct date and time in the BIOS. You need a new CMOS battery. That's most likely one of the errors.

While you're in there, have it load defaults.

Been having very, VERY annoying issues with my computer as of late. I could be playing a game. All is well until all of a sudden my keyboard and mouse just completely stop working (although the computer still appears to be running fine, just keyboard and mouse stop). So i restart my computer, only to get a message along the lines of "bios checksum error" with very fast, constant beeping. I reset my computer again and i get nothing on my screen, the light just turns amber. After turning my computer strait off and back on again, it comes back to life and begins working again like nothing ever happened. (until the next time it happens).

I am really struggling to find out what the problem actually is, but i THINK that it might be the motherboard, but im not sure. What do you guys think? Sound like a motherboard problem?

My system specs are as follows:

CPU: Pentium 4 2.2Ghz
Video: GeForce 6600GT
Mobo: ECS 661FX-M (I know ECS is crap, this is why i think it might be the mobo)
PSU: Thermaltake 430w

I recently attempted to flash the bios of my Intel D845PT motherboard and incorrectly used Intel's flash (for mb PT84510A.86A) program instead of Gateway's (for mb PT84510A.15A), who was the OEM of my board. Now I recieve a "CMOS/GPNV Checksum Bad" each time I boot. I have researched the Internet for solutions and have performed the following with no success:

1. Reset BIOS to factory default (The settings don't seem to save, as they are the same as before I altered them when I boot back up)
2. Return BIOS settings to settings before the flash (I didn't write them down, but I only remembered disabling Silent Boot as far as altering from default)
3. Clear CMOS (I removed the CMOS battery for 5 minutes with the pc unplugged)
4. Re-flash BIOS (Changed the jumper on the motherboard to maintenance mode and flashed the bios from there, and attempted to use first Gateway's, then Intel's OS independent BIOS update programs).

Thank you in advance for any advice you may give.

Well, if you get the bad checksum you should be able to reflash. Does your floppy work? If so, find the boards number and pcb version and flash to a working bios.

I am trying to work through using the recovery module to fix this issue.

I have located my driver disck and gotten to the recovery module.

I selected the windows and then entered the administrative password just like I saw on other sites.

My problem is now I don't know what to do next.

One of the sites said to change directory to:
cd windows\system32\drivers

but the system can not find that directory.

The blue screen said that the image winiet.dd is possibly corrupt but I can not find this file.

I am sure it is just something simple but it had been 20 years since I have used DOS to navigate and I need a little hand holding on this one.

"Could not measure system memory performance."

So I did something that made something happen again so I need help, again.
I had changed my CPU, motherboard, and RAM; the CPU needed a different socket (2011-3), and so with that new motherboard required different RAM (DDR4)
I'm pretty sure the sudden change in hardware is the cause of this, and a few other things that I'd like to think I had solved by myself.
I have a feeling this is an easy fix, what did I do wrong and what can I do to fix whatever this is?

Hello guys, the last week I've been strugling with these nasty BSODs. At first I thought it was my HDDs as ntoskrn.exe somewhat hinted towards that from googling it. My HDDs have been causing a lot of trouble earlier as well due to their somewhat long years of service. However, I've recently reformated my computer and installed W7 on a brand new Corsair Force GT 120GB SSD hoping the BSODs would go away, they didn't.

I googled BSOD and I stumbled upon this forum and I thought I'd give it a try. I'm somewhat desperate, as I need my computer working for both work, school and amusement.

I've been trying to run Memtest in order to test my memory but without any results. I'm also currently running on only on 4GB chip instead of two, to see if the problem still exists. Also, without any results.

This is the second time I'm writing this thread btw, I was just about to post it and my PC crashed.

Here is my two logs + dxdiag (last crash didn't generate a log oddly enough).

Here is additional hardware/gear that I use:

Razer Megalodon 7.1 Headset
Razer Naga
Logitech G19
Logitech C920 (Webcam)
Corsair 750W PSU

My temperatures are also good. Both CPU and MB idles at around ~25. GPU's all good too. I'm also using a Corsair 650D chassi with dustfilters at both air-income so dust is minimal. On top off this, I use airpressure to clean away dust somewhat regularly and I also did exactly this 2 days ago when I reinstalled the pc.

Hi, I am having a problem with my newer computer, I just got this rig a few months ago and never had a problem until last Thursday. It Blue Screened on me while I was installing ARC GIS 10.1. From then on it randomly crashes. (I have previously installed ARC GIS 10 and never had a problem.)

I keep things updated (windows and drivers) and I do think windows forced through an update earlier that day. I un installed ARC GIS 10.1 and the windows update, didn't make any difference. I have also ran the Windows Mem test and Auslogic BoostSpeed/ Registry repair. I keep getting "Bad Pool Header" and "Page In Nonpage Area" and I can't seem to find something that triggers it. So far it hasn't crashed in Safe Mode without network access. I tried it once with access and it crashed. Currently have windows checking the drives for errors ( I have 4).

I think I attached the proper dump files. This is my work computer so this is kind of causing a big problem. Thanks in advanced for the help!!

I have been getting these "Bad Pool Header" and "System Service Exception" BSODs for about a day now (the "Bad Pool Header" one tends to pop up more often then the other btw). I ran a registry cleaner which didn't work and ran memtest this morning and it showed that my memory was fine. The BSODs tend to occur more often when I am playing a game or running some program that uses a bit more memory but it also happens when I am just on the internet. On the other hand, last night I did nothing but surf YouTube for 3 hours and didn't get a BSOD at all. However, since then I haven't been able to do anything for more than 10 minutes (without being in safe mode) without it crashing, and this morning it completely froze until I turned it off. My OS is Windows 7 Home Premium 64bit. It came preinstalled from the manufacturer and unfortunately I do not have the install disc. The entire laptop is less than 2 years old and there have been no major hardware changes and I have never reinstalled the OS.

Hi all,

So I'm kind of stuck.. I currently have the problem where I am in an endless cycle of "loading files" -> "Windows Boot Manager" (see: How To Boot Into Safe Mode On Windows 8 (The Easy Way)).
I have tried to load all of the options -- and none successfully load.
I also end up at a OneKey Recovery as well.. unfortunately, the laptop does not have initial backup or user backup images.
I have a Windows 8 CD for repairing purposes.. however, I cannot load the BIOS/UEFI to change the boot order to load the optical drives first. I have also tried to remove the CMOS battery to fix it.. did not work. .
Also - Windows Boot Manager:
Windows Setup [EMS Enabled] -- does not load properly (leads to OneKey Recovery) Safe Mode (does not load properly) Safe Mode with Networking (does not load properly) Safe Mode with Command Prompt (doesn't load - tries to boot and load all files onto partition that is too small.. can't change partition?)

I can boot to Safemode, Safemode w/ Networking. I tried last known config, but when it gets to the desktop - it switches to the BSoD.

I am hoping with the attachment, someone can help me. More power to everyone.

Hey all, I've gotten a couple blue screens over the past couple of days. I just replaced my GTX 660 with a 960 over the past weekend and received a Bad pool header BSOD on the 9th, then today (the 11th) 2 Reference by pointer BSOD's. I've done some research and it seems to all point to driver errors. My brother just got the same GPU and is having a massive amount of blue screens with slightly different errors. Is this an issue with Nvidia?

Thanks for your help! All req'd info should be attached below

Hi everyone,

I recently have noticed more and more BSODs. I had this problem about 6 months ago and was able to track it down to drivers that came from Daemon tools. I cleared all that out and it fixed the issue. I don't think these new BSODs are related but they might be.

This seems to be happening randomly. It happens roughly every 2 weeks and early in the morning (1am, 6am, 9am, etc.) but not at a consistent time. As far as I can tell, I am not doing anything or leaving open any specific program that triggers this. There doesn't seem to be a consistent pattern.

I ran the DM Log Collector and uploaded the zip file here. Any help would be appreciated. Thanks!

Hi guys, I ask you a lot of help because I'm in trouble up to my neck. I try to be as detailed as possible.
I have a Packard Bell with initially installed Windows Vista Home Premium (I don't know if 32-bit or 64-bit). Over time I updated it to later versions, and in fact before the problem I normally had Windows 10.

Brief introduction: as you know, telematic lessons have started in the world at home. So I installed Microsoft Teams and so far everything is ok. I noticed, however, immediately that the fan of my old PC with more than 10 years of intense work was starting to fuel quickly. While I was thinking about how to solve, the inevitable happened: during a lesson the PC freeze in the screens, and after waiting 5-10 minutes I turned it off by the button. By re-accessing it, this screen appeared, as the title says:

"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."

If you do not have the disc, contact your system administrator or computer manufacturer for assistance.

I need help with a formula. I used this formula YEARS ago and now I can't remember how to do it.

Column A


Column B

So if Column C equals 1 I want Column D to equal Red, if 2 then Blue, etc. I have about 50lines of information so I don't want to do a long "if, then" formula. I believe the formula was a combination of the vlookup and match formulas.

Can anyone help?!?!

when booting i get a 'bios checksum error. detecting floppy drive media. insert boot disk.' I've changed out the floppy drive, changed the ram, made various changes to the bios setup re: the floppy drive. all to no avail. resetting about 10 times when i boot eventually gives me a good boot. the clock seems OK with the correct date and time. Any clues? Many thanks.

BIOS is going bad or the battery. You usually only get checksum errors when the BIOS loses it's infomation.

Hey all,

I've been having this problem ever since i installed google drive sync client and mega sync client for windows and moved an 11GB folder of pictures and videos over to it from the dropbox sync client/folder for windows.

Now, no matter what i type in the search field in the windows explorer window, "No items match your search" always comes up.

I've tried:
deleting and rebuilding index in "indexing options"
switching file types to include file contents as well in the advanced options
restarting the PC

* I very highly doubt installing the two sync clients had to do with this problem, rather it was moving the folder that caused the issue

** Search seems to work fine for the dropbox client/folder, mega client/folder, as well as for C:\

*** Troubleshooting says there is nothing wrong with the system

**** What's really odd is when i EXCLUDE the google drive folder from indexing, windows search works!

Help is greatly appreciated!

I am working on a laptop for a friend and receive the "Bad_POOL_Header" BSOD about 15 seconds after Windows loads. I do not receive the error in safe mode. I have attached the dump files but cannot run the System Health Report as this service will not run in Safe Mode. Can someone point me in the direction of what driver and/or software is causing the BSOD?

System Specs:
Asus TravelMate 5542-3590
Windows 7 32-bit OEM
AMD Athlon II P340 Dual-Core
2.00 GB RAM
ATI Mobility Radeon HD 4250

Thanks in advance

A:BSOD, "Bad_POOL_ Header" , Almost Immediately After Windows Loads

There's only two minidumps present, one dated from Oct 2011, and the other is from today. What doesn't make sense is that the syslog said that it saved the crashdumps for previous crashes yet I don't see their minidumps here. Are these the only dump files present in C:\Windows\Minidump directory? It does appear like there's an issue with a disk driver or a filter driver that filters disk I/O, which may explain why memory dumps aren't being generated (if they aren't).

Anyways, this does indeed look like a driver issue, but the minidump itself offers no valuable data aside from it being disk-related, and minidumps are used to find patterns in crashes so one minidump isn't enough here.

Therefore, I recommend turning on Driver Verifier. Do not select the following checks: Force Pending I/O Requests, IRP Logging, and Low Resource Sim. Select all other checks. Make sure to restart system after you finish setup. If you experience a boot loop afterwards, go into Safe Mode by pressing F8 prior to Windows logo and disable DV there. Provide us any new crashdumps that may be generated from this.

Btw, as a hint, the process that was running during this particular crash I'm seeing was SetAPM.exe, an Acer bloatware application that's designed to "improve" power management functionality. I recommend you uninstall it. Perhaps that's the bugger that's causing all this.

In Windows XP, fully updated, I have several folders full of mp3's and want to see the bit rate and duration. I right click on a column heading and select "Bit rate". I then click on "More..." so I can get to "Duration", and I select that one too.

But all the figures in the "Duration" column appear to be in "hours" and "minutes", so I see "00:04" or "00:03", but what I want is "minutes" and "seconds".

Any thoughts as to how to change this?

Have you tried changing the boot sequence inside the BIOS?

Normally pressing F2 or F12 on the computer will solve this.
