What are 2 uses of the speakers on a computer?
If you mean the external speakers they are for playing sounds, i.e. music, sound from video or alerts from the operating system.
If you mean the internal speaker it is for alerting the user of more critical problems, i.e. a missing component (processor, graphics card), overheating or some sort of hardware failiure.
Can you change your computer motherboard?
Unless your computer case is specially manufactured for the motherboard that is installed, you can change the motherboard. You can start by getting the manufacturer and model of the current motherboard (often found to one side of the video card slot), and taking that information with you when you purchase the replacement. Any competent PC parts vendor can determine what motherboard will work as a replacement.
When trying to restore a failed system what should you do next if Recovery console does not work?
Get your documents from the disk and reinstall the OS.
Most Likely the file is toast. The ASR process probably destroyed the file, if it were not already destroyed.
Why is your computer slow to start up?
Do a Defrag. Go to START, PROGRAMS, ASSESSORIES, SYSTEM TOOLS, then do a system cleanup, then defrag.
Clean up any unused programs on your PC. Go to Control Panel, ADD/Remove Programs and remove anything (kid games, etc) you know you don't use for sure. If you're not sure, don't do it.
Kim Komando has some good info at her site www.komando.com and there is a good software package (not expensive) that I bought at Costco called SYSTEM MECHANIC that will do system diagnostics. They probably even have a download for sale on the net. Or at Amazon.
Another thought is just to go to Google and type in your laptop brand and "slow boot up" or "slow start up". I have found lots of nerd discussion boards with useful info this way. Good ideas from others who have had similar challenges on a multitude of problems. MSN has discussion boards on computer problems, for example. As does Microsoft. Click on Tools, Windows Update, and do your updates, then surf around the site for troubleshooting info. If all else fails, go to Data Doctors or another Computer Geek fix it shop and they will usually take care of it.
Answer1. Run a security scan for your laptop. Don't be lazy and think you can deal with the infection files later. If you frequently visit various website and download files often, your laptop will have high risk to be infected. It is really necessary for you to have an anti-virus software to protect the laptop computer. This is the most important step to speed up laptop.
2. Remove hidden junk files on your laptop to speed up your laptop. How long haven't you clean up the junk files? Too many junk files on the system will slow down the laptop speed by occupying the system resource. To delete those hidden junk files, please: Open "My Computer"--"Program files" and then choose the programs you never use or want deleted then just delete the folder.
3. To speed up your laptop computer, you also can disable some unneeded services and programs on the laptop startup. To do this please: Click Start--Run--type in msconfig--under the services tab you can disable the unwanted services. In addition, under the "Startup" tab, you can choose and disable some of them in order to speed up laptop boost speed.
4. Scan and fix Windows registry on your slow speed laptop. Perhaps you will ask that why you can speed up your laptop by cleaning registry errors. Registry stores all of the configuration settings in the system like a brain to human. Any incorrect registry settings, corrupted registry will make your laptop run unstable. If you leave the corrupted or malicious registry entries there and continue to run the damaged system, this potential risk will not only slow your computer down but also crash your system. If you never repair registry errors on your laptop, you can try this method to speed up your laptop.
How do you know when your laptop battery is fully charged?
mcVolt chargers and most OEM chargers have lights to show if the charge is finished. Typically, you will see changes in the green or red lights on the charger to indicate the battery is charged. For example, if a red light appears during charging, the light will turn off, or a green light will illuminate when the charge is complete. Consult your charger's manual for more details.
When would you disable the serial port?
In the past, both the serial and parallel port were the most common means of data transfer and communication used by PCs. Serial ports were used for devices such as modems, mice, and serial port printers. However, in newer PCs, both the serial and parallel ports have been replaced by the use of USB ports. You should only disable serial port(s) if you are absolutely certain that auxiliary devices such as modems; printers; mice; etc.. are USB based and that your PC has enough USB ports to accommodate all of your auxiliary devices. Note: If at some point in the immediate future, you plan to sell your PC, it might be wise to leave the serial port as is.
a modem that connects to your PC either directly or through a router/switch/hub, windows.
The modem must be connected to the internet, either through Coax', phone-line or other.
A2. Cleaning with toothpaste would be likely to leave the cleaner in the tiny grooves. And it is not common for small scratches to interfere with the playing of a CD or DVD. If you can detect the scratch in the reproduction, the time may be right for a visit to the shop.

What are the two files for backup registry?
The windows XP registry consists of several files, loaded together they constitute the "registry"/
These files are Software, System, SAM, Security, Default, and UserDiff. They are located in Windows\System32\Config and are usually hidden or considered protected system files.
One other registry file is called NTuser.dat and is located in the users Documents and Settings folder.
What are the Pros and Cons of being a computer technician?
Positive aspects of becoming a computer technician include being able to fix your own computer. The job has room for growth, there is flexibility in career options, and computer technician jobs typically pay well.
1. the computer is switched on.
2.computer loads data from ROM and checks whether all the major components like processor,hard disc are functioning properly.
3.computer loads bios(basic input/output system) from ROM to determine the machine's fundamental configuration and environment.
4.computer loads the operating system from the secondary storage(hard disc) into ram .this allows the CPU to have immediate access to the operating system
,which enhances the performance and functionality of the overall system.
Why system maintenance is important?
System Maintenance is very important because you need to keep your computer and system up to date and safe. It is very important to run security and windows updates everyday so that you can reduce the chance of getting viruses and spyware. It is also important to the performance of the machine because if you don't keep your computer clean then it's not going to run as good as it should.
On a personal computer all processing functions are contained on a single electronic chip called a?
microprocessor
What was the problems with early computers?
they were not that much powerful or you can say fast and they heat up very fast they need a fan as big as a room for only computer.
it all began with a machine Herman Hollerith began designing in 1881 to tabulate the census in a much modern and faster way than the methods the government had in those days. when the spectations of the 1890 census promised to take very long this deviced saved the day since he achieved ten years of tabulation in one year. Hollerith formed his company to sell the machine and became part of IBM.
What computer component are things you can touch?
The partss you can touch are the key board..........disk drive....... and the system........but the hard drive...if you wreck that your computer is done for..... you can touch the inside but i wouldnt. and be careful of the wires.
What is the basic part of the computer and its function?
Hardware is physical part of a computer and software is piece of code that runs the computer. For instance, violin is hardware and music is the software.
New modern computers used small electronic components, which can be imprinted on the surface of silicon chip.
The most generally used electronic component is transistor.
Transistor work as a like a amplifying valve for a flow of electrons.
The transistor is a solid-state device, which has no moving parts. Basically, it is a building block for constructing more complex electronic components.
Vacuum tube was used before the invention of transistor.
Since than transistor have been made smaller and smaller and making more and more of them to be imprinted on silicon chips.
Central processing units is referred to as a
“brain” of computers.
It is hardware with in a computer and carries out the instruction of computer program.
CPU runs the code and manipulates the data, while components have quite more passive roles.
For instance storing data.
In older days, CPU requires one or more printed circuit board.
After the invention of microprocessor, CPU could be remained with in silicon chips.
There are two main components of CPU, arithmetic logic unit which performs the arithmetical and logical side and control unit which carry the instruction from memory, decodes and process them.
Random Access memory is temporary storage device.
Random access memory let any data to store and access quickly in random order while in other storage device such as Hard disk, CDs, and DVDs etc. read and write the data only in predetermined order. It is because of mechanical design limitation.
The main features of RAM are that it can keep its state as long as power is on.
Hard drive is a long-term storage for bytes as files and folders.
The hard disk drive read the write the magnetic patterns magnetic patterns on a spinning metal disk to store data.
Flash drive is also a solid-state drive with silicon chips to store bytes.
In both case, hard disk drive or flash drive maintain its state of storage even when the power is turn off.
Why is adding RAM a performance advantage?
Computers with more RAM can handle more information without crashing. Computers have to store all of the data coming from all the the devices in the computer until the processor can process the data and this data is stored in the RAM. If you have small amounts of RAM, it will fill up and then all the devices pause until the RAM has more room for data. So the more RAM that a computer has the less waiting the devices have to do on account of the CPU having data already waiting to be processed. daman155 In most modern systems using Windows XP, Linux, etc.. more RAM is better. This enables the system to keep more applications and data such as documents spreadsheets and Internet pages in the systems main storage area, which is RAM. When you have more applications and data loaded than can fit into RAM, the system will remove what it sees as idle data not being immediately used and move it from ram to "Virtual Memory" on your hard disk. This "Virtual Memory" or Swap Space is VERY SLOW. This means when you go back to what was deemed idle memory, it takes awhile to swap back into RAM. So unless you run out of both RAM and disk space, you may not crash, but without more RAM you will not be able to open as many applications or documents as you may like. --Veggivore--
What is the first indication that ram has been removed?
Hi,
If you want to know whether RAM is in the system or not, Just press "Window" key and "Pause Break" together. It will give you the whole description of your computer including your operating system and you can see whether RAM of the computer has been removed or not under "computer".
Just try this and let me know if I could answer your question currectly..
any circuity in a computer shouldn't be handled without a esd(electro-static-discharge) wrap as a safety precaution to prevent damage to components, although there maybe some components which are not sensitive to static. the main parts of the computer which definitely shouldn't be handled without esd wrist straps are high impedance components such as the cpu,gpu or any other flash chips or microprocessors.
When should you not wear a wrist strap?
You should always where a ground strip when working on the internals of a computer. You should always unplug the computer from everything before working on it and ground yourself to the computers metal case. This will equalize the static electricity between you and the mother board and her components.
Check BIOS settings, make sure that the adapter is enabled. Check that the cable is not damaged and working properly. If you have burned the port. You can get a PCI extension port with Network Interface Port.
I presume you are asking for an example of a Brief command prompt? First go to a CMD shell by selecting the windows button in the bottom left corner and typing CMD after "RUN". A black screen will appear where you can enter any prompt such as: ipconfig - IP confirguration
Dir - directory listing
