Tips: Safe From Hackers

Some tips are safe from hacker attacks. There are several things that must be taken to ensure that your account is not lost and used for things that are not desirable.

1. Do not use an email for various purposes. So, for example for facebook use 1 email, for banks using an email, to use an email forum for all your personal accounts to be safe. Because if your email and hit only 1 hack, then the hacker can hack facebook account, twitter, myspace, paypal, plurk, or even worse your bank account.

2. Do not use passwords that are stupid or easily recognizable, such as phone number, Date of Birth, Name of Parents and info about him as a password where it is the stupidest thing in the doing of the user.

3. Different Places, Different Password. So, for the forum should use the first password, to FB a second password and so on for the security of your account.

4. Unique password. Use a unique password as joint caps and symbols for safety. Examples of secure password that: aDeH4nWb973.

Ok. Quite simple, short, simple, and safe. Hopefully these tips useful.

How To Format Hard Disk

If you feel something is wrong with your hard drive, or would like hard drives like new, one way you can do is reformat it repeated.

Following Repeat Steps Format Hard Disk:
1. Back up your important files that exist on the hard drive because the format command will erase all existing files on your hard disk. If you have a cd-rw drive or dvd-rw drive can back up with a way to burn your files into cd or dvd, or if you do not have a CD burner, just use a flash disk, no matter if it's enough to hold your data.

2. Then the next step is to create a Windows boot disk / rescue disk on a floppy diskette 1.4 MB. It aims to boot diskette into the floppy not directly through your hard drive. The term you would use microsoft os dos existing on the diskette that you created.

3. If you do not have DOS, try to borrow or buy a CD that contains DOS, I used to get on the course, so no need to create a system on diskette. Just stay put, use for bootable.

4. Change Bios settings when the computer is turned on you must go directly to the display for setting the bios boot sequence options. When a new computer is turned on, press the delete key until the bios screen appears on your computer monitor. Change the boot sequence with the sequence of the first floppy disk.

5. Format Hard Disk. After the boot order in bios to be replaced, you insert a floppy disk and then restart your computer. Later you will be automatically booting the computer from the floppy and select the boot without cd-rom to get faster boot process. After entering the command prompt a:, type format c: and press enter. The same can be applied to another partition harddik adjusted by the number of your existing partitions. If you have a partition of 3 pieces then add the command format d: and e format:.

6.Kalau you use a bootable CD, just insert it, it will automatically appear in the DOS boot.

Now your hard drive to be like new again.

How to Safely Modify BIOS Settings On Computer

BIOS is the foundation of a computer Though small in size, regardless of the BIOS software is windows would not be able to work Never mind the work, komputerpun will not be lit without a BIOS. So as much as possible we have to keeping the existence of the BIOS is still stable. It is true that its BIOS is read only or read-only course. So much less likely to be damaged. But many cases of damage caused by incorrect BIOS settings as well as viruses and some other cause. Well, how modifications to the BIOS settings to make it safer?

BIOS Therapy

As new technologies emerge and old bugs are discovered, computer makers often publishes updated BIOS version that can solve problems and improve performance. Check the Web site updateterbaru your PC maker. But first make sure you have the latest BIOS version number; usually flashes on your monitor right after you turn on the system. (Press the Pause button when it flashes too quickly.)
Updating the BIOS is easy, but you must do so with caution. Usually you need to run a small program from a floppy disk. But if a problem occurs, you can only lament the motherboard that can no longer use. So make sure that you have read all the instructions in the readme file BIOS update. And always do exactly what the instructions say it.
If the BIOS is the PC's subconscious, then the Setup utility is the foundation for building character PC. The utility has user settings to control hard disks, memory, graphics cards, power saving, USB ports, and other hardware. The program is normally included in the disk, but now it is stored in a ROM chip with a PC BIOS.
To open Setup, simply press the button (or key combination) that you're prompted to enter when the PC starts up. Each BIOS manufacturer uses different keys - Delete, F1 or F10. Your screen should show the button or what buttons to press for Setup right after it displays the BIOS version number. If not, check your system documentation.
Because the Setup utility created by the BIOS manufacturer and are in the same chip with the BIOS, it is often called the BIOS Setup utility. And because of this utility to save the settings under the clock / calendar chip - chip complementary metal-oxide semiconductor, or CMOS - then often referred to as the CMOS Setup program. (CMOS chip has its own battery to maintain the chip's settings even when the PC is turned off.)
The Setup utility has an abundance of hardware settings, ranging from the obvious, like the time on your PC's clock, to the arcane, such as the number of "wait states" that coordinates the flow of data between RAM and CPU.

First, Do not Ruin

When working with PC Setup utility, use the same rule of thumb taught in early brain surgery: If you do not know what something does, do not mess with. Carelessness change wait state or settinglainnya can degrade performance or even cause system crashes.
If you think you've accidentally changed 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 vendorPC you've fine-tuned the system, the BIOS maker's default settings may not be optimal.

Backup your settings before making changes. When the battery that powers the clock / calendar chip die, the settings you die with it. Setup utility if you have a backup option, use it. If not, record the settings in the paper - or press the Print Screen key to each screen in these utilities (but this does not always work).

What to Look For
Before you begin, read through the user manual that came with your PC or motherboard. Many manuals offer a brief explanation of each setting. Settings vary by manufacturer and model, but you should find these on almost all PCs:
Optimization and compatibility setting: Setup utility often contains settings for the hardware performance. Sometimes this is not set optimally at the factory, especially on PCs made to order or generic. Scanseluruh Setup program. AGP mode settings and DMA settings are good candidates for optimization. These settings are also useful for troubleshooting a newly installed hardware: Turn off or reduce a given setting can trigger non-incompatible graphics card, CD-ROM drive, or other device that has happened before.
Setting hard drive: You'll find a table, usually on the second page or the Advanced and under the title "IDE", which lists all the configuration parameters for EIDE hard drives directly connected to the motherboard. (SCSI and EIDE hard disk with no expansion cards will run the program their own configuration.) While most PCs are made over the last few years can seamlessly detect and configure the new hard drive, some require manual installation. Read your documentation of your new disk on the procedure 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 assigned as drive A: or B: you. This is a setting to check if you have floppy-drive problems. Some Setup utility has security settings `` Floppy Read only individual that prevents your data is written to a floppy disk and deleted from your PC.
Boot sequence: This setting determines where the first times when the PC boot-up instructions. Example: `A: then C:`, `C: then A:`, or `C:,` Zip drive. To boot from a CD-ROM drive, Zip, or LS-120, you'll likely have to change this setting.
Password protection: If this is enabled, the BIOS will ask for a password before booting up. Be very careful with this one: If you forget the password, you'll 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.
Setting IRQ: When you need an extra IRQ settings for the new hardware, you need to free up one IRQ by disabling unused features, such as serial ports, parallel port, or USB port.
Parallel port settings: Choose the most suitable mode for 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 questions of hardware, but sifting through Web sites to get advice that could be trusted enough to spend time. Sometimes the fastest way to get answers is the old-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 the PC and the things you might not know about. If you are looking for a thorough 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 in a concise style that clearly delivers the information you need, without you having to look for (www.oreilly.com).

Gross Drive

Clean up, clean up at the weekend leaving a layer of dust covered the entire office, and you kuaatir CD-RW drive may be dirty. How should I clean it?
Maybe I should not. Rubbing can inhibit even the most delicate sensitive laser on the drive, so if is not broke, do not clean. When performance declines, or if your drive is unable to read the media, try some well-directed spray from a can of compressed air - available for less than U.S. $ 10 in computer stores. Be sure to use a plastic straw that came with cans. And keep the spray slowly; rushes of air can cause condensation to accumulate moisture on the interior of the drive. Before using a cleaning kit such as a CD-RW U.S. $ 15 artificial Kensington Drive Guardian (www.kensington.com/html/1080.html), seek recommendations from the manufacturer's drives, some recommend, but others do not.

Stopping Old Program

Some software programs that really old just do not work in today's high-speed PC. If you have old programs that lock or 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 kewww.cpukiller.com to download it.

How To Display Back, Folders Hidden Due To Shortcut Virus ?

Shortcut Virus lately often unsettling computer users. Generally this virus spreads rapidly through the flash media. Although it is not so dangerous, but the virus is quite annoying. Because the virus is making all the existing folders to be hidden and replaced with a folder shortcut from the original folder. If we open the show hidden files / folders not necessarily be able to see the original folder.

There is one way of showing the folders, to return again as usual is to use the command at a command prompt in windows. But the first time we did the first scan the computer and make sure that the virus is gone down to its roots. If the virus is not removed first, then our efforts will be futile, so the virus will be acting up again.

Okay, we just practiced this way. The steps are as follows.

1. Open a command prompt windows, way is by typing cmd in the Run menu, or press the Windows key + R, then type cmd.

2. Then type the name of the location of the drive / removable disk followed by the sign ":" (without brackets). Press enter. For example: d:, f:, i:, etc..

3. After that, type attrib / s / d-s-h

4. Wait until the process is complete. So the hidden folder will appear again as usual.

5. Good luck ...
