Windows Boot Problems
Every time Windows starts up, a number of programs are run automatically. Most of the application that you install using default installation like a virus scanner or an instant messenger application, also load when the Windows boots up. These applications use the system memory and take time to get going, leaving little portion of the memory for other programs to open. Some programs sneak into the list of programs that are loaded during start ups.

These errors are usually thrown out when the system tries to read data from a damaged CD or DVD. The respective drive may grind or whirl away and your system may slowdown just before a CRC error is displayed. System crashes, incomplete download and buggy software can also cause this error.
