Windows 7: How does kernelbase.dll crash an application?

How does kernelbase.dll crash an application?

Sometimes I either get kernelbase.dll crash or ntdll.dll crash. (APPCRASH)

Sometimes suddenly explorer.exe crash, followed by ETDCtrl.exe (Touchpad process).

Does download and replacing kernelbase.dll solve the problem?
What kind of application are usually having conflict with them?
Thank you

Darryl, here's my usual disclaimer: I'm not an expert at anything.

As I understand things (and I could be completely off the mark on this), kernelbase.dll is kinda like a second generation of kernel32.dll. Kernel32.dll was originally written for 32-bit operating systems while kernelbase.dll is for primarily 64-bit systems. Rather than re-write the entire kernel code, kernel32.dll and kernelbase.dll are supposed to work work together.

They are the main files (for lack of a better description) that contain the core processes or heart of the operating system. At startup, they load into memory and regulate things like user runs, programs, memory management, input and output streams, task managment, and disk management. They contain the operating system's fundamental processes. They can also be accessed by more than one program at a time which is why it's usually difficult to narrow down why an error occurs or which program or application is at fault.

Sometimes the kernels become damaged or corrupted. A virus, failure to shut down the computer properly, a poorly written program, etc can be the cause. Because they are system files, the can sometimes be repaired by running a system file checker scan from an elevated command prompt. And if that doesn't work a Repair Install of the operating system will usually fix the problem. But in extreme cases (like a major virus infection) only a clean install will work (that means replacing everything on the hard drive - operating system, all installed programs, etc.)

Hope this helps a bit.
