What does computer crash really mean?
Crash or system crash is serious computer failure. It may cause a computer program aborts unexpectedly or the operating system itself stop working, even unbooatble.
For computer program, such as, Microsoft Office, the problem may be errors in itself or conflicts with other programs. Usually, it hangs suddenly, and then, a few seconds later, ask if you want to wait or exit.
But if the program is a critical part of the operarting system, such as, registry, the computer system may crash or hang, throwing you a kernel panic or fatal system error.
Then, why computer crashes suddenly? It's likely to be:
1. Corrupted system registry files.
2. Disorganized files.
3. Malicious software.
4. Too little available memory.
5. Device driver.
6. Power surges.
7. Hardware problem like overheating.
