Speed Up Your Computer Through Pen Drive
When you set up a device to work with ReadyBoost, Windows shows you how much space it recommends you allow it to use for optimal performance. For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your device does not have enough available space for ReadyBoost, you'll see a message telling you to free some space on the device if you want to use it to speed up your system.
For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your drive or card doesn't have enough available space for ReadyBoost, you'll see a message telling you to free some space on it. For best results, use a flash drive or flash memory card with at least double the amount of available space as the amount of memory (RAM) in your computer.
Turn ReadyBoost on or off for a storage device
ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards.
1. Plug a flash drive or flash memory card into your computer.
2. In the Autoplay dialog box, under General options, click Speed up my system.
3. In the Properties dialog box, click the ReadyBoost tab, and then do one of the following:
- To turn ReadyBoost off, click Do not use this device.
- To use the maximum available space on the flash drive or memory card for ReadyBoost, click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it'll use the rest to boost your system speed.
- To use the maximum available space on the flash drive or memory card for ReadyBoost, click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it'll use the rest to boost your system speed.
- To use less than the maximum available space on the device for ReadyBoost, click Use this device, and then move the slider to choose the amount of available space on the device you want to use.
Move the slider to choose how much space you want to designate for boosting your system speed
4. Click OK.
What to look for in a flash memory device
Here are some tips on what to look for when selecting a USB flash drive or flash memory card to use with ReadyBoost:
- The minimum amount of available space recommended for ReadyBoost to effectively speed up your computer is 1 GB.
- For best results, use a flash drive or flash memory card with available space of at least double the amount of memory (RAM) in your computer, and preferably four times as much memory. For example, if your computer has 1 GB of RAM and you plug in a 4 GB USB flash drive, set aside at least 2 GB on the flash drive to get the best performance gain from ReadyBoost, and preferably the entire 4 GB. How much memory you need depends on how you use your computer. Keeping a lot of programs open at once uses more memory.
- Give ReadyBoost 2 GB to 4 GB of space for best results on most computers. You can reserve more than 4 GB of space for ReadyBoost on most flash drives and flash memory cards. (Storage devices formatted with the older FAT32 file system can't store more than 4 GB.) You can use a maximum of 32 GB of available space on any single removable storage device with ReadyBoost and up to 256 GB total per computer (by inserting up to eight USB flash drives or flash memory cards into the same computer).
- To work with ReadyBoost, a USB flash drive must support USB 2.0 or higher. Your computer must have at least one free USB 2.0 port where you can plug in the flash drive. ReadyBoost works best if you plug the flash drive into a USB port directly on the computer, rather than into an external USB hub shared with other USB devices.
- If you want to be sure a USB flash drive works with ReadyBoost, look for a note from the manufacturer that the flash drive is "Enhanced for ReadyBoost." Not all manufacturers list this on their packaging. If there is no mention of ReadyBoost compatibility, the flash drive still may work with ReadyBoost.
- There are many different kinds of flash memory cards, such as Compact Flash and Secure Digital (SD) memory cards. Most memory cards work with ReadyBoost. Some SD memory cards don't work well with ReadyBoost due to issues with the SD card interface. ReadyBoost will display an error message if you attempt to use one of these cards.
I hope this helps! Please express your experience and opinions through comments.

Why My Computer Crash/Hang All The time?
Have you ever face the hang problem in your computer…..hummmmmm the answer may be “yes”…..I have seen many such problems in my friends computer….They most of the time try to play computer game but they face hang problem in their computer….why such thing happens…what does it answer? Can we do something for it? Ok. .let’s find its answer…..
In computing, a hang or freeze occur when either a single computer program or the whole system becomes unresponsive to keyboard and mouse inputs. In a hang, the window affected or the whole computer screen becomes static, the latter case includes the mouse cursor. It is contrast with crash, where a program stops working and is not responding, or exits abnormally after encountering a problem When no other input works, the power cycle must be restarted by an on/off or reset button.
Hangs are not limited to client personal computers with a graphical user interface. Servers can hang as well. In those cases, the server ceases to respond to requests. These sorts of hangs are typically addressed by a solution far more complex than an on/off or reset button.
The most common causes of these troublesome problems will be covered here. They fall into the following general categories:
Hardware (Defective or mismatched components in your computer):
Hardware can cause a computer to hang, either because it is intermittent or because it is mismatched with other hardware in the computer (this can occur when one makes an upgrade). Mismatched hardware is common, even some of the large computer manufactures do insufficient analyses and testing when they select the components that make up their systems. Many components that make up a computer just don’t play well together. Some modems just don't work well with specific video cards. Some sound cards are incompatible with certain main boards. The list goes on. Many manufactures only look at the cost of a given part, not its compatibility, thus they can often produce unstable computer systems.
A computer may seem to hang when in fact it is simply processing very slowly. This can be caused by too many programs running at once, not enough memory (RAM), or memory fragmentation. It can also be caused by hidden programs which were installed secretly, also known as spyware.
Hardware can become defective. Mishandling the internal components of a computer can prematurely age them, which reduces their lifespan from decades to weeks or months. Many hardware failures are subtle and will not cause the computer to completely stop working, but will cause intermittent problems. Adding new internal components to a computer, especially by under-trained technicians, can cause static electricity damage to the other parts of a computer. Electro Static Discharge "ESD" is similar to when you walk across the floor touch a doorknob and receive a shock, but it's a much smaller spark. An ESD created by a person just working on the inside of a computer is so small that we can't even feel it, but it can cause great damage to the computer's internal components.
Other hardware related problems could be caused by dirty or loose internal connections, stalled or slowly turning cooling fans, improper or loose heat sinks, bad or intermittent memory, or any of a thousand other things.
Aluminium Migration & ESD (Premature ageing and “Electro Static Discharge” can make a computer very intermittent):
Semiconductors do wear out! Contrary to the beliefs of many, integrated circuits grow old and die, or become intermittent. How they do that varies; modern "chips" as used in computers, have literally millions of transistors printed on a small "chip" of silicon no bigger than your finger nail. Each microscopically small transistor is connected to the others, on the surface of the chip, with even smaller aluminium or copper wires. These wires are only a few thousand atoms wide. Over the years, the thermal stress of turning the computer on and off can cause tiny cracks in the wires. As the computer warms up the wires can part and cause the computer to stop working. Even a few seconds of off-time can cool the system enough to allow the wires to re-connect, so your computer may work just fine for a few minutes, or hours, then after it warms up, it may fail, letting it cool off can bring it back to life for a few minutes or more.
By far the most common failure mode of a modern integrated circuit is aluminium migration. The small aluminium wires of a chip are arranged in parallel rows very close to each other. Heat, electricity and time, can cause the aluminium of one wire to slowly flow across the gap between the wires, and eventually short out the chip. Most quality chips are designed to minimize this migration, and usually will run for decades before they short out, but many things can speed this failure process. Cheaper parts, excessive heat, marginal circuit design, or bad handling, can cause the premature death of a chip through aluminium migration.
The most insidious and least understood cause of chip failure is ESD "Electro Static Discharge". Chips can be electrocuted by very small amounts of static electricity (much smaller than can be felt) can kill, or make a computer chip intermittent. We human beings create lots of static electricity. All the dozens of people who have touched the chips inside your computer, from manufacturing the chip, building or repairing your computer, or adding new parts to the inside of your computer, have had the opportunity to touch, or mishandle, the chips inside your computer.
Operating System (Some versions of Windows have bugs that can cause these problems):
Windows 7 and Windows 8 have a database of information "The Registry" that controls how windows and all the programs should operate and cooperate with each other. As new programs are added and old programs are removed, the registry can become damaged. Many times this damage will cause the computer to become unstable, more freezes and error messages. Sometimes the only solution to this kind of problem is to completely clean your hard drive and reinstall the operating system and all other programs.
Drivers (Buggy or down-level drivers can cause many problems):
Drivers are little programs written by the manufacture of a given component like video cards, sound cards, modems and so forth. These drivers are installed in, and become part of, the operating system. Errors in drivers or older versions of these critical components can cause many intermittent problems.
Software (Some programs have bugs in them that can cause these problems):
The software that's in your computer can have bugs or is just poorly written, and when its run can cause all manner of trouble in the computing environment. The trouble caused by one program may not show up until yet another, unrelated, program is latter run. Some programs that make heavy use of memory may not release all the memory that was assigned to it, when it is closed. This can cause fragmented memory. Fragmented memory can slowly grow as programs are used, eventually growing to a point where the free memory is insufficient to allow the computer to run properly.
Adbots, Parasites, & Spyware are a family of small programs that are installed in your computer, (usually without your knowledge), during the installation of some shareware/freeware programs. Hundreds of useful programs, some of which you may already have in your computer, carry an imbedded "spyware" program. Spyware allows advertising agencies to receive reports about where you are surfing and what web-ads you click on.
Most of these Adbots, or spyware programs, DON'T collect specific information about you, but only report general demographics, and therefore are NOT stealing your name, credit card, or other personal information.
Blue Screen of Death:
If you're experiencing Fatal Exception Errors, what we call the "Blue Screen of Death" or BSOD, more times than not it's due to the video driver. Often after installing a new program or upgrading an old one, the new code will make demands on the video driver that the original driver can't handle properly. This results in a very unstable computer. Finding the EXACT make and model of your video card, then downloading, and installing, the latest drivers from the company's web site may fix the problem.
The NT-style BSOD displays error codes that explain what just happened inside the kernel. The STOP error displays five error codes in the following general form:
STOP: 0x#### (0x####, 0x####, 0x####, 0x####) Error Name
For example:
STOP: 0x00000019 (0x00000000, 0xC00E0FF0, 0xFFFFEFD4, 0xC0000000) BAD_POOL_HEADER
The first code represents a specific error, while the others are additional data whose meaning depends on the error code.
A new version of the error screen has been seen in the developer preview of Windows 8, released in September 2011. Rather than displaying detailed technical information about the error, it simply displays a short explanation that system needs to restart, the technical name of the error and a sad emoticon. Also it contains a lighter shade of blue in the background.
These are some causes for which our computer get hang. My loyal reader if you know more about why our computer get hang then put your comment in our dynamic comment box. We will come back with one fresh article soon.
