    wow; thanks for responding so soon..wasnt sure if i would get feedback...i actually have not installed anything recently...back in january the computer would just randomly freeze up when starting up, when on would act very unstable, sometimes the usb drives would go in and out or stop working altogether until i disconnected and reconnected the device such as portable hard drive,flash drive, camera, etc...started taking an extremely long time loading when i reboot the computer..at times would freeze on xp screen that comes on before you get to the login screen...finally attempted to reinstall os which would freeze, recently deleted hard drive partition since i got msgs that hard drive was corrupt but computer freezes in the middle of reformatting..sometimes if i try quick format/install it goes for a while and then gives msg that hard drive is corrupt or not connected properly

No problem, once and awhile I just cruise around on here. You can narrow the problems down by either replacing the ram/hardrive/expansion cards/cpu with known working parts, or putting the parts into another working cpu untill it stops working. My guess would first be to try removing the hard drive. Once you get a working combination, add the parts in untill you find a the issue component. If the problem persists, your looking at a bad harddrive controller or hard drive, that undermines your entire system's stability. If I am right your working with a socket A motherboard and thats pretty old so I wouldnt be suprised if it may be quitting.

Compaq Presario 2500 stopped loading windows XP with a prompt STOP: c0000221 {bad Image Checksum} The image COMCTL32.dll is possibly corrupt. The header checksum does not match the computed checksum.


This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.

During the boot process you will see on the screen to press delete to enter setup
Press and hold delete during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
click start control panel date and time you can make your adjustments to the date and time from there also right click on the date and time on the bottom toolbar (bottom of screen) you should see Adjust date and time tab
hope this helps you

Could be lots of things. First check you power supply, then memory. See if any of the components are getting very hot (be careful not to burn yourself). From there it will be kinda hit and miss till you find what is wrong. May be easier to look for a compatible motherboard on ebay.

Find and fix errors in your system BIOS
BIOS Patcher can find and fix errors in your system BIOS (only AWARD BIOS for now) and also it can add or open new features, i.e. some features that your BIOS has but they are closed by manufacturer of your motherboard. It scans rom file. If it finds any known errors it fixes the errors. If it finds any closed features it opens it. hope this helps

Your best beet is to either do a google search or check out what is available on ebay for that mo bo. Often cmos chips are available for purchase.
Flashing is never guaranteed and often does not work. If you are sure the cmos is bad your best bet is to get the cmos chip with the correct bios already on it. And if it doesn't work then the issue is within your mo bo. My cmos went belly up on my Dragon also - very frustrating because it was a great mother board.

Booting problem


There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:
  • CMOS Battery may not be functioning properly. The battery life may have expired.
  • Your BIOS may have been updated (either by user or possibly a virus)
  • The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires you to shut down your computer before shutting off the power).
Solutions to CMOS Checksum Bad Error The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.
CMOS Battery may not be functioning properly
If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer’s manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery’s information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated
If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.
The Computer may not have been shut down properly
Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue

Cmos checksum error defaults loaded


Make sure the battery your using is brand new. If it is then go ahead and get into the Bios and make sure the date and time is set properly. Once you do that then go ahead and save the changes and exit.

After this go ahead and see if the CMOS exit checksum defaults comes up if not then go ahead and turn off the computer and unplug it. Then after about 5 minutues plug the computer back up and turn it on and if the message doesn't come up then its resolved.

If the cmos checksum error comes back up then try a brand new battery, should be a 2032 battery and then go thru the same steps in setting the date and time and save changes and exit and if the message doesn't come back then unplug the system again and leave it unplugged for 5 minutes. Now plug it back up and if the message stays away the problem is resolved. it the message comes back then that means the motherboard isn't reconizing the batteries and the motherboard would need to be replaced.

Checksum error


Hi Oliver, the most common error related to the message,
(Bios Rom Checksum Error). Someone has left a floppy disk in the floppy drive. Once the floppy disk has been removed press the reset button on the PC, your windows will start normally. Next place to look is in your bios.
Open your manual to page 27.
Enter your bios & go to the title Advanced BIOS Features. Check First, Second & Third boot devices they should be as follows. Floppy disk drive, CD-ROM drive & primary hard disk drive. If both of the above are ok than try clearing the cmos/bios by resetting the cmos jumper (JP1) location on page 5. Descriptions of page five on page 6. CMOS settings on page 9.
When your system restarts re-enter your cmos & reset up your bios settings. Lastly if none of the above has fixed the error message, than remove the cmos battery & check its voltage. It should maintain 3volts. If yours' is lower than 3volts replace the cmos battery. There is one other possible fix. It’s an option not given lightly. Flashing a cmos/bios is not recommended unless all other options have failed.

Checksum error


Hi Faster Fester. You don't need to install the new BIOS.

You get the checksum error just because you're CMOS battery have run out. Just try to replace the CMOS Battery and you're problem will be solved.

Grydor.
