Recently a friend asked me such a question, his computer for a while and then closed, not too long after the screen black screen, display no signal input. His problem is actually very simple, that is, the VGA line sent. This question is also a more common problem. Such problems are frequently encountered by many computer users. In fact, as long as you have some understanding of the working principle of the computer, these devices can not damage the simple failure of their own hands to eliminate.

First step: monitor color is not normal, we recommend that you first use the elimination method, as far as possible to eliminate some simple problems, because the display color display is not normal for many reasons, such as monitor color Control Panel is not set up, the display of wire rod contact bad or rust can lead to such problems occur. The second step: If you are newly bought

This article illustrates how to monitor the occurrence of deadlock in DB2 UDB through concrete examples. There are two types of monitors in the DB2 UDB: The snapshot Monitor and the event monitor. A snapshot, as its name suggests, is a slice of the database's continuous state, and through the snapshot monitor, you can

Hello everyone, nice to meet you again. What do you bring for everyone today? Oh, you may notice the title, yes is we will ignore a system tool. Why would you introduce this tool, is because my own experience let me notice the value of the tool, the first few days the computer will often slow response, very card, but the self-feeling is not the problem of hardware, and the running of the program should not be too much resources, want to go do not know why, I thought of trying to see what was cau

1. top-Linux System process monitoringThe top command is a performance monitor that can be used in many Linux/unix versions, and it is also a tool for monitoring system performance often used by Linux system administrators. The TOP command periodically displays all running and running and updates to the list, showing CPU usage, memory usage, swap memory, cache size, buffer size, process control, users, and more commands. It also shows running processe

Most people when installed, for graphics drivers are often very focused on, and generally can be installed correctly, but for the display driver is usually not noticed, but in the installation let Windows automatically recognize. However, Windows sometimes does not recognize the model of the monitor correctly, and therefore cannot install the most suitable driver, which leads to the above phenomenon. In this case, Windows usually recognizes the

Many readers are interested in System Safety Monitor (SSM. It is a Russian system monitoring software that monitors system-specific files (such as registries) and applications. Program To protect system security. Some features are more powerful than the winpatrol we have previously introduced. Install and start (you can manually run syssafe.exe) SSM in the installation directory, click Close this windows (Close Window) in the pop-up logo window t

Here we will introduce the C # Lock keyword. It can define a piece of code as a critical section. A mutex can only be executed by one thread at a time, while other threads must wait. C # language is worth learning a lot. Here we mainly introduce the C # Lock keyword, including the locking of an object in the monitor class. C # provides a lock keyword, which defines a piece of code as a critical section. A mutex section allows only one thread to

The Framework provides three locking mechanisms: the Monitor class, the Lock key word, and the Mutex class. 　　In general, lock and monitor can lock objects or functions, while mutex is generally used to lock functions and ensure that functions are synchronously called between different threads, without being affected by the thread priority. When the lock and monitor
