Should I run a disk check (chkdsk) if I'm experiencing 'rundll32.exe' errors?

Yes, running a disk check (chkdsk) can be beneficial. It helps identify and fix file system errors, which can sometimes contribute to DLL loading problems. Open Command Prompt as administrator and run `chkdsk /f /r C:` (replace C: with your system drive if needed). You may need to schedule the check to run on the next system restart.
