【 Weak current College 】 peaseant computer operation

<br> <br> As the it products is increasingly common, many families have to purchase a home computer. Because of the varying levels of computer, will inevitably be some "newbie" or even "prawn" in computer operations, there are some .more or less taken for granted that some seemingly wrong operation inadvertently incorrect operation might make your computer instantly "West", or even hurt your health. Based on this, I will in the long-term use of computers in the accumulated experience and it should .be noted that the "whole story" of misunderstanding, with a view to improving the level of the computer all the pitfalls, let the computer better for our work and faithful service. <br> <br> Myth one: clean the monitor to use .pure ethanol <br> <br> Monitor as human-computer exchange of important medium, its screen time inevitably sticky dust and dirt. Many of my friends took it for granted that alcohol especially high purity (95%) are the best detergents. To .the contrary, the monitor (CRT) is generally on the screen there is a layer of special protective coating, used to anti-static and glare, alcohol as a good organic solvents are very easy to break off this special coating, to monitor the effect .of the show. <br> <br> Correct approach: the monitor's screen including its shell, do not use alcohol, gasoline, detergents, solvents, if there are conditions please use the dedicated monitor cleanser. If the conditions are not met, you .can go to the market to buy some bottles of purified water to the monitor screen and shell clean. In addition, be careful when cleaning the screen, do not use ordinary thick towels, buy 1 ~ 2 blocks quality better glasses cloth. <br> .<br> Myth two: open the chassis so that the box of computer accessories "streaking" is the best heat dissipation <br> <br> Summer is approaching, many "Rookie" even includes many DIYer to enhance heat dissipation or facilitate disassembly and .Assembly hardware, have to choose a cheap and convenient way of cooling solutions - let the computer "streaking". However, I think this is very wrong. First, although the resolution of the heat, but the "grim broken belly chassis," let .the hardware in easily accumulated exposure to dust, if the "dust" will become the computer's killer. Second, this approach is very harmful to human health. We all know, the CPU, motherboard, power supply and so hardware is high electromagnetic radiation sources ., and the chassis for our masks the vast majority of electromagnetic radiation, is our health protection using the PC's "God". If only for the heat and let our bodies directly exposed to the high electromagnetic radiation, take health joke is not worth the candle .. <br> <br> Myth three: shutdown immediately covered with dust cover <br> <br> Many of my friends in the purchase of new computers are very attention PC dust, specifically customized a dust cover, this criticism, but shut down .immediately cover the undesirable on a dust cover. Original, keep-the-box, the display also has a large amount of heat is emitted, the temperature of the various electronic components are very high, the need for a gradual cooling process, if you .'ll cover the dust cover, very detrimental to the hardware of the heat, or even seriously affect its service life. <br> <br> Correct approach: to shut down after 1 ~ 2 hours, standby tank heat powder out before they can .use the dust cover. <br> <br> Myth 4: electric plug in various computer peripherals <br> <br> Many of my friends in a variety of hardware, for easy often not shutting down plug PS / 2 mouse, keyboard, .and the various series and parallel port devices. These are seemingly ordinary, but very dangerous, light and the resulting system or hardware does not work correctly, you have the hardware interface or motherboard. <br> <br> Correct approach: in addition to .USB, IEEE1394 interface and serial hard drive, ordinary desktop various peripherals are not belt electric plug, so friends in other hardware operations do not be afraid of trouble, be sure to shut down power failure of proper operation, so as not to cause unnecessary losses .. <br> <br> Myth 5: contact computer hardware, electrostatic undefended <br> <br> Many of my friends while in the subconscious know static is computer hardware potential "killers", but because of the emphasis is not enough, more .of the operations of the lazy and the chance exists, often for "violating" hardware operation that "spark" with a slight flicker, PC motherboards, memory, video card, and other parts in just a moment "fragrant Xiao Yu thumbing". Due .to static electricity in our life is everywhere, our contacts and repair computers easy to accumulate large amounts of static electricity, therefore must take effective measures to avoid static electricity to a computer in the high-precision parts fatal damage. <br> <br> .Correct approach: first of all, to guarantee a reliable ground computer chassis, the open computer host box contact computer hardware front, the best hand and a metal part outside of the chassis or other grounded metal contact, through a short exposure to release the body .with static electricity. In addition to removing the computer hardware can be placed in the anti-static plastic bag to take care of this, in the hardware of sensitive operations through wear antistatic ring can be very good anti-static effect. Finally, the static .electricity generation and release of a seasonal, particularly in winter, so more care should be vigilant. <br> <br> Myth 6: optical drive as "DVD player", "clean" CD become killers <br> <br> Many friends .now are equipped with a CD or DVD drive, in order to achieve the look up work correct, often use the optical drive play normal VCD, DVCD and DVD video. In fact, this is a very bad habit. While this is temporarily convenient for .myself, but if things will greatly reduce the service life of the last of the optical drive to "scrap". Main reason is the drive in read ordinary discs will frequently change the motor speed and frequency of the laser head, a long time may cause .optical drive machinery parts wear and aging of the laser head seriously. <br> <br> Correct approach: for maintenance of the optical drive, you can add your own favorite DVD copy computer's hard drive slowly to enjoy, you should use and no optical .drive, see discs cannot drive whenA DVD player! <br> <br> CD-ROM as a consumable, in use for a period of time tends to varying degrees, a reading of the disk capacity of decline, many friends have "smart move ."- borrowed from General cleaning-cleaning DVD player on the optical drive for cleaning CD to improve or restore CD reading disk capacity. In fact, this is a misunderstanding of the household of the DVD player including VCD, DVD, because it works different on .their lower at x generally 2X, 4X, use cleaning discs can play a role of cleaning; but now the speed of the optical drive often around this time of 52X cleaning plate has no proper role, on the other hand because of the high speed rotation .of the disc will not only hit the scratch or even distortion of laser head, a no-compromise optical drive "killer" <br> <br> Correct approach: If you wish to improve the ability of the reading disc CD-ROM, you .can make professions open the optical drive with a cotton ball cleaning or appropriately increase the transmission power of the laser head. Of course, the best approach is usually focused on the care and maintenance of the optical drive. <br> <br> Tips: .1. an optical drive is reading disc is an optical drive lights also do not force pressing CDROM eject button on the Panel, it's a good idea, led off the action does not have read up before pressing the Eject key, otherwise if the optical drive .can fail the spindle motor. <br> <br> 2. on the CD, be careful not to go direct with the hands to push the CD tray, CD warehousing because push intensity or angle of deviation easily drive drive failure. The correct approach .is to press the Eject key enables the CD tray automatically back to the warehouse. <br> <br> 3. CD read must promptly remove, not be stuck in the optical drive. Because although there is no read / write operations, but the .computer each time you start it automatically detects and prefetching optical drive, this will not only reduce the operating speed of the system, but also to the life of the drive. <br> <br> Myth 7: shutdown does not have to cut off .power supply <br> <br> Often see some friends once you are finished using the computer, for easy implementation in a system running away, after the shutdown command is not the host power completely cut off (that is, unplug the power outlet, .from strips away the exhaustive), sometimes even monitor and speakers, and other peripheral devices are still in working condition. This is in fact to computer hardware laid risk, because the system shutdown state does not completely cut off the power, the power within the .chassis, motherboard, power supply is switched on, still and in case of voltage fluctuation or encountering Thunder weather, it is easy to result the motherboard, power supply and various peripheral devices thoroughly corrupted. Here we advise you to be on the safe side shutdown .after thoroughly cut off the power. <br> <br> <br> <br> <br> <br> <br>.
