Computer problems can be perplexing and every computer user has wished time and again that there was some permanent solution to them. Some errors are quite common and are encountered again and again. Some common errors you may encounter are the msvcr71.dll windows 7 error, which occurs when this particular DLL is missing or the registry or associated application is corrupt, and the stop: c000021a error, which is raised by the kernel when it senses that some important system process, like winlogon.exe, has suddenly halted.
