Weak current College】 【clean computer errors.

Now, the computer has been used as a common household appliances into the family, the computer use time, also have to do the cleaning and maintenance, but how to do the cleaning and maintenance of the computer, but there are some mistakes.
Myth 1: use absolute alcohol cleaning computer monitors. In General, the alcohol is a commonly used solvents that can dissolve some not easy to wipe away dirt, if you just used to clean the monitor enclosure, no adverse effects. But be sure not to use alcohol to clean the monitor screen, since some of the more high-end monitors are on the screen, and coated with a special coating, the monitor has a better look, once you use alcohol to clean the display screen, it will dissolve this layer of special coatings, on display from causing bad effect.
Myth two: use alcohol to clean the drive's laser head. There are a lot of computer books and tell everyone you can use absolute alcohol cleaning laser head, sometimes on the laser head cause great harm. Different laser head, using different materials, for part of the CDROM, the laser head lens section uses a similar to organic glass material, if you use alcohol to clean it, alcohol is solubility its surface so that it becomes opaque and thoroughly corrupted optical laser head. There are also part of the CDROM, bald lens surface layer with vacuum deposition coating method for coating the film up to adjust the refraction coefficient, the laser in a specific wavelength no losses through, so bald Hin blue. But this film will dissolve in alcohol, with alcohol to clean the laser head, will wipe the dust of dissolved this layer films, despite the short term optical drive read disc capacity will increase, but the laser head have been compromised. Better cleaning laser head is directly with a clean absorbent cotton wipe the dust from the laser head, or take a small amount of acetone cleaning dip the laser head. Also do not use alcohol to clean the computer disc, it will dissolve the disc surface coating.
Myth three: cleaning CD to clean the VCD or DVD drive. Now there are many cleaning CD VCD, friends for sale would use it to periodically clean the CD, the CD has two rows of small brush, if it is in general use of VCD, VCD machines using a 2 x CD-ROM drive, the disc rotation speed and fast, so when small brush in VCD gently sweep out bald, can play a role in cleaning the bald. But now the computer is used by the drive speed is much faster, and often are more than 30 x DVD drive, disc rotation speed is close to some of the old hard drive before, when using this VCD disc cleaning CD/DVD drive cleaning, these two rows of small brush became bald killer, not only will scratch the bald, serious also knocked Askew bald so it fits, unable to read data from the CD.
Myth 4: regularly use floppy drive cleaning plate cleaning diskette drive head. This kind of use tissue paper do disc floppy drive cleaning plate is also quite common, when put into the floppy disk drive, perform the dir command. But to be honest, at first I suspected that the practical effect of the clean-up, imports do disc easily on the tissue paper wrapped around the head on fiber, if you then drop with reels on the sale of cleaning liquid together, head might even cut the floor wet after disc, more trouble. In fact, now the floppy using the frequency is not high, completely having to constantly clean, if you must clean the heads, you can use a good quality of the new floppy disk, format it repeated several times, usually the head can be cleaned up. If the head pollution more serious, you can open a floppy disk drive, with a clean absorbent cotton dip for cleaning cassette head cleaner cleans carefully.
