>>What is standby compared to hibernate ?
Short form of above: Standy shuts down most devices and pauses execution, but the system is not off entirely. Hibernate saves the current memory and state information to disk, and then shuts down entirely. Upon power up, Windows checks the disk for the saved memory and restores it instead of the normal boot sequence.
>>why does windows xp usually crash when hibernate is checked ?
Because some device drivers and/or software can't handle being stopped. Hardware devices, for example, must often be reset when powered up, but if the people who wrote the driver didn't bother to support standy/hibernate, the driver might think the hardware is still ready and when it tries to use the hardware it is not ready so it crashes.

Fast resume from Hibernate or Standby is a Windows XP Professional Top 10 feature. Check out the rest of the list.
If you use a laptop, you can take advantage of the Standby and Hibernate features in Windows XP, which reduce the drain on battery power when you leave your laptop running. With Windows XP your laptop can enter Standby and Hibernate faster, and it will return to full power much more quickly as well. Standby and Hibernate can also help you save energy in the office by reducing power to your desktop machine when you aren't working.
Standby for Fast Take–Off
With Standby, the system shuts down your monitor, hard drive, and other devices, but maintains power to random access memory (RAM). Your open documents and applications are stored in RAM as if your system were fully powered, so you can pick up where you left off very quickly. Many newer laptops resume from Standby in less than two seconds with Windows XP.
Windows XP includes an improved algorithm that tells your monitor, hard drive, and other devices when to come out of Standby. It restores devices in the most efficient order and, wherever possible, restores more than one device at the same time.

Hibernate Turns It Off, but Saves Your State
In the same way, Windows XP helps your computer start faster when you use Hibernate. This feature saves the contents of RAM to your hard disk in compressed form so you can turn your laptop or desktop computer completely off. When you turn on the power, your documents and applications are open just as you left them so you can start work quickly.
Windows XP reduces the time it takes to compress the memory data and save it to your hard disk. The time it takes to resume from hibernation can vary considerably. Newer laptops can resume from hibernation in 20 to 30 seconds, but the actual time depends on how much data was saved in RAM at the time you started hibernation.
