Nowadays, computer has become very popular worldwide. Since users are at different levels of computer knowledge, there will be various computer problems. Generally speaking, many computer problems are just little cases. As long as we learn some computer trouble shooting skills, we can solve these problems on our own. Of course, if we develop a habit of thinking, we don’t need to ask others for help when our computers fall into trouble. Here let’s learn some computer trouble shootings together.
1. Power sockets, switches and many peripheral devices are independently supplied with power. It is not enough to turn on the power supply of the mainframe computer only when running a computer. For example, if the power supply of display is not provided, it probably causes the illusion of “blank screen" and "computer crash" ; if the power supply of external modem is not on work or power plug is loosen, you can't go on line, transfer file, and even identify modem. Printers and scanners are independent power supply equipment. When you face with peripheral faults of the independent power supply devices, you should first check whether power supply of the equipment is normal, or check whether power plug / socket is in good contact, or check whether power switch is on.
2. Connectivity problem. Peripherals and computer are connected by data lines. Cables in poor contact will lead to the abnormal peripherals. For example, the loosened display connection can lead to partial color screen and blank screen; the printer is not connected to the computer even if you see it put next to the computer. You should check if the cables of different equipments are correctly connected by yourself.
3. Setting problems. If there is no display in your computer, it can be caused by the disordered line frequency or compressed width, or even just adjusted brightness. If your speakers couldn't work, it may result from your volume switch is shut off. If your hard drive is not recognized, you should first check if position is wrong… To get more details about the peripherals setting, you should try to check on your own to find the essence of the problems.
4. System new features. Many troubles are sometimes caused by the new features of the hardware or operation system. For example, if your host has taken with an energy-saving function, it will automatically shut down the display and hardware power supply if nobody uses the computer or no program is operated for a long time. If you click you mouse or the keyboard, it will recover soon. You will mistake your computer issues as hardware or display going wrong, unless you know the new features.
To better know your computer, you should learn more about your computer, its peripherals and new features. If possible, you can also consult the computer expert and equip yourself with corrective computer knowledge.
