If Windows is the friendly face that displayed projects to the world of computers, the BIOS is the dark side of the subconscious which is responsible for thinking. BIOS (Basic Input / Output System) is a code for the fundamental functions of a PC, such as collecting beats from a keyboard button or put pixel to screen.
This small program works behind the scenes, translating commands the people-friendly Windows becomes zero and the one who understood only by your hardware. And as the human subconscious, the BIOS can be a powerful influence on behavior and performance of your PC.
BIOS Therapy
As new technologies emerge and old bug is found, computer makers often publish the updated BIOS version which can solve problems and improve performance. Check your PC manufacturer Web sites about the latest updates. But first make sure you have the latest BIOS version number, usually a brief appearance on your monitor right after you turn on the system. (Press the Pause button when kilasannya too quickly.)
Updating a BIOS is easy, but you must do so with caution. Usually you need to run a small program from a floppy disk only. However, when problems occur, you can only lament the motherboard that you can no longer use. So make sure that you have read all the instructions in the readme file updated BIOS. And always do exactly what it says clues.
If the PC BIOS is unconscious, then the Setup utility is the foundation for building character PC. The utility has a setting to control the user's hard drive, memory, graphics cards, power saving, USB port, and other hardware. The program is usually included in the disk, but are now already stored in the same chip with the BIOS ROM PC.
To open the setup, simply press the button (or key combination) is recommended to you to be included when the PC start up. Each BIOS manufacturer uses a different key - Delete, F1, or F10. On your screen should show the button or what buttons that need to be pressured to setup right after the screen displays the BIOS version number. If not, check your system documentation.
Because the Setup utility created by the BIOS maker and be in the same chip with the BIOS, it is often called the BIOS Setup utility. And since this utility to save the setting in the chip's clock / calendar - chip complementary metal-oxide semiconductor, or CMOS - it is sometimes called the CMOS Setup program. (Chip CMOS have their own battery to maintain settings for the chip even if the PC is turned off.)
Setup utility has an abundance of hardware settings, ranging from immediately obvious, such as setting time on the clock of the PC, to the invisible, like a number of "wait states" which coordinates the flow of data between RAM and CPU.
First, Do not Destroy
When working with PC Setup utility, use the same rule of thumb taught in early brain surgery: If you do not know what to do something, do not deal with it. Blunder change the wait state or other settings can degrade the performance or even cause system crashes.
If you think you have been accidentally change the settings when you're working with the Setup utility, stop immediately and start from scratch again. All Setup utility has a menu option that lets you exit without saving changes. You may see also the option to restore settings to default values. Ignore this option: If your PC vendor has been doing fine-tune the system, the BIOS maker's default settings may make it not optimal.
Backup your settings before making changes. When the battery that keeps the chip's clock / calendar to die, your settings to die with him. When the Setup utility you have a backup option, use it. If not, record the settings in the paper - or press the Print Screen key for each screen in these utilities (but this does not always work).
What's Wanted
Before you begin, read to the end user manual that came with your PC or motherboard. Many of the manual offers a brief description of each setting. Settings vary by manufacturer and model, but you should find this on almost all PCs:
Optimization and compatibility setting: Setup utilities often contain settings for hardware performance. Sometimes this is not set optimally at the factory, especially on the PC are made based on order or generic. Scan the whole setup program. Setting AGP mode and setting the DMA is the leading candidate for the optimized. These settings are also useful for troubleshooting new hardware is installed: Disable or reduce a given setting can trigger instability kompatibelan graphics card, CD-ROM drive, or other devices that occurred previously.
Setting hard drive: You'll find a table, usually on the second page or Advanced, and under the title "IDE", which lists all the configuration parameters for EIDE hard drives that connect directly to the motherboard. (SCSI and EIDE hard disk drive that has no expansion card will run the configuration program itself.) While most PCs are made over the last few years can seamlessly detect and configure a new hard drive, some require manual installation. Read your new disk documentation about these procedures and use the options on-screen to make changes in this table.
Floppy disk: This option lets you set the type of floppy drives (3.5 inch, 1.44 MB, for example) that you set as drive A: or B: you. This is a setting that needs to be checked if you experience any problems floppy-drive. Some utilities have setup security settings `` Floppy Read only own that prevent your data is written to the floppy disk and deleted from your PC.
Boot sequence: This setting determines where the first views the PC as boot-up instructions. Example: `A: then C:`, `C: then A:`, or `C:,` Zip drive. To boot from the CD-ROM drive, Zip, or LS-120, you seem to need to change this setting.
Password protection: If this is enabled, the BIOS will ask for password before boot up. So be careful with this one: When you forget the password, you have to reset the motherboard jumpers or removing the CMOS battery, which will cause you to lose all the settings, or you even have to buy a new motherboard.
IRQ settings: If you need extra IRQ settings for new hardware, you need to free up one IRQ to disable unused features, such as serial ports, parallel port or USB port.
Parallel port settings: Select the most suitable mode for the hardware. ECP or EPP mode can greatly speed up the printers and other devices.
CPU temperature and fan RPM: Two critical parameters should be checked periodically to ensure they function properly.
Hardware Help Offline Internet is great for finding answers to the questions of hardware, but investigating the Web sites for advice that could be trusted enough to spend time. Sometimes the fastest way to get a response is fashioned way: with a good reference book. Below are two of the best.
Upgrading and Repairing PCs (www.upgradingandrepairingpcs.com) by Scott Mueller (U.S. $ 60) is a classic book that covers everything you need on your PC and the things that you may not know. If you are looking for a comprehensive reference, breadth and depth of this title Unbeaten (www.quepublishing.com).
PC Hardware in a Nutshell (www.oreilly.com/catalog/pchardnut2) by Barbara Fritchman Thompson and Robert Bruce Thompson (U.S. $ 40) is a good practical guide to buying and using PCs. Loaded with advice concise style that clearly provides the information you need, without your having to look for it (www.oreilly.com).
Gross Drive

Maybe you should not. Rubbing can hamper even the most delicate sensitive laser on the drive, so if not broken, not clean. When performance declines, or if your drive can not read the media, try some well-aimed spray from spray cans of air - is available at a price of less than U.S. $ 10 in stores computer. Make sure to use a plastic straw that came with cans. And keep the hose slowly; pressure spray can cause excessive moisture condensation which accumulates on the interior drive. Before using a cleaning kit CD-RW as U.S. $ 15 artificial Kensington Drive Guardian (www.kensington.com/html/1080.html), seek a recommendation from the drive manufacturer; some recommendations, but others do not.
Stopping Old Program
Some software programs that really old just can not function on a PC at high speed today. If you have old programs that lock or raises an error message every time you want to run it, try CPUKiller; free and easy to use utility, which lets you slow down your PC as little or as much as you want. Go to www.cpukiller.com to download it.
