There are several different ways that kernel.dll errors can show up on your computer. Here are some of the more common ways that you might see kernel.dll errors:

• "Kernel.dll Not Found"
• "This application failed to start because kernel.dll was not found. Re-installing the application may fix this problem."
• "Cannot find [PATH]\kernel.dll"
• "The file kernel.dll is missing."
• "Cannot start [APPLICATION]. A required component is missing: kernel.dll. Please install [APPLICATION] again."

Kernel.dll error messages might appear while using or installing certain programs, when Windows starts or shuts down, or maybe even during a Windows installation.
The context of the kernel.dll error is an important piece of information that will be helpful while solving the problem.

Cause of Kernell.dll Errors
Kernel.dll errors are caused by situations that lead to the removal or corruption of the kernel DLL file.
In some cases, kernel.dll errors could indicate a registry problem, a virus or malware issue or even a hardware failure.

How to Fix Kernel.dll Errors
Important: Do not download kernel.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of kernel.dll, it's best to obtain it from its original, legitimate source.
Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the kernel.dll error.

1. Restore kernel.dll from the Recycle Bin. The easiest possible cause of a "missing" kernel.dll file is that you've mistakenly deleted it.
   If you suspect that you've accidentally deleted kernel.dll but you've already emptied the Recycle Bin, you may be able to recover kernel.dll with a free file recovery program.
   Important: Recovering a deleted copy of kernel.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that.
   
2. Run a virus/malware scan of your entire system. Some kernel.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It's even possible that the kernel.dll error you're seeing is related to a hostile program that's masquerading as the file.
   
3. Use System Restore to undo recent system changes. If you suspect that the kernel.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem.
   
4. Reinstall the program that uses the kernel.dll file. If the kernel.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.
   Important: Try your best to complete this step. Reinstalling the program that provides the kernel.dll file, if possible, is a likely solution to this DLL error.
   
5. Update the drivers for hardware devices that might be related to kernel.dll. If, for example, you're receiving a "The file kernel.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.
   Note: The kernel.dll file may or may not be related to video cards - this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly.
   
6. Roll back a driver to a previously installed version if kernel.dll errors began after updating a particular hardware device's driver.
   
7. Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the kernel.dll file. If this DLL file is provided my Microsoft, the System File Checker tool should restore it.
   
8. Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The kernel.dll file could be included in one of those updates.
   
9. Test your memory and then test your hard drive. I've left the majority of hardware troubleshooting to the last step, but your computer's memory and hard drive are easy to test and are the most likely components that might cause kernel.dll errors as they fail.
   If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible.
   
10. Repair your installation of Windows. If the individual kernel.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.
    
11. Use a free registry cleaner to repair kernel.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid kernel.dll registry entries that might be causing the DLL error.
    Important: I rarely recommend the use of registry cleaners. I've included the option here as a "last resort" attempt before the destructive step coming up next.
    
12. Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the kernel.dll error, this should be your next course of action.
    Important: All the information on your hard drive will be erased during a clean install. Make sure you've made the best attempt possible to fix the kernel.dll error using a troubleshooting step prior to this one.
    
13. Troubleshoot for a hardware problem if any kernel.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.
    

Applies To
The kernel.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.

The way to fix ATI2DVAG.dll errors is to first restart your PC into "Safe Mode With Networking". This will basically allow your PC to boot up without all the drivers and software which can cause it to crash. To do this, you should first restart your PC and then press F8 continually before Windows loads. After that, you should then select "Safe Mode With Networking" to boot your PC into that mode. When in safe mode, you should download a new version of the ATI Graphics Driver from the Internet, which should fix most of the problems you've been having with it. This can be done by downloading the driver from the ATI website and then re-installing it in Windows.

After updating the driver, try your PC in "normal mode" again to test to see if the problem has been fixed. If you find it hasn't fixed the issue, you should then go back into safe mode an manually replace the ATI2Dvag.dll error on your PC with a fresh copy of the file from the Internet. On top of that, you should also clear out the "registry database" of your PC with a registry cleaner. The registry database is a central storage facility for Windows, which basically keeps all the settings and options that Windows needs to use to run inside. This part of your system is very important and used to load up many different DLL files. To ensure no registry errors are causing problems on your system, you should download a registry cleaner program from the Internet, install it and then let it fix the errors your PC has.

The error message indicates your operating system is not able to load one of the files required for Yahoo messenger to work.

To make sure Yahoo messenger is installed properly, download the installation files and save them to your desktop.

Once you have the installation file...

Open the control panel and uninstall the existing version of Yahoo messenger. This will remove the program from your computer and clear out the registry entries that were created during the first install of Yahoo messenger.

Reboot your pc and then run the Yahoo messenger installation file you downloaded to your desktop.

The system reboot is a precautionary measure to ensure that none of the files used by Yahoo messenger are loaded into memory during the reinstall.

Check that your usb ports are functional by plugging in another known good working device, mouse, etc. Most devices want you to install the CD before you connect the hardware. When it's asking you for the drivers, be sure you point it manually to the folder on the disk with the .INF files. The INF file tells the computer what DLL and System files to load to use your device. Check under the Device manager to see that the device is installed all the way or if it has a question mark on it saying something is wrong.
