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

Transferred from: http://www.kuqin.com/shuoit/20140219/338066.htmlFor system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 1

Having a second screen can help you view multiple open applications at the same time. You can also connect the projector so that everyone in the room can see your screen. You can use a DVI, VGA, or HDMI cable to connect most monitors and projectors. (Some devices can even connect wirelessly.) For information, see projecting to a wireless monitor using Miracast. Your computer may have one or more of the following ports. DVI, VGA, and HDMI ports Afte

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
