computer mouse not working properly

computer mouse not working properly

Though the mouse is not the most robust part in a computer, if it has some malfunction, it would seriously affect your computer working well. Usually if a mouse is working irregularly, it would have problems like that the pointer is movable on the screen but later it freezes up, or sometimes the pointer may jump on the screen erratically, etc. If such failure happens, how can you repair it?

First of all, you need to clean the mouse pad. Because the pad may have a lot of dirt or grease as you drag and drop your mouse on it heaps of times.

Then if the first check can not work, go to the second step. But before you do this, you have to know what kind of mouse you are using.

If it is a ball mouse, you need to take the ball apart from your mouse and clear up all the obstruction like dust and dirt built-up on the ball and inside the mouse. With certain computer knowledge you even can disassemble the whole mouse and completely clean it.

If it is an optical mouse, you have to check its bottom to see whether there is something like a piece of tape there. Besides, test this mouse on another surface like a sheet of paper to see if it can work regularly.

If the mouse still fails to work, try to reinstall its driver, or download some driver tools like Driver Checker to help you find out the most suitable mouse driver.

Additionally, the opening or closing of a process or the high CPU usage also can make a bad impact on your mouse working. However, the failure also could be a broken mouse, or that it has been used too many times and should be obsoleted.

Keyboard Not Working

Keyboard Not Working

The real test to ensure that the keyboard is not at fault is to try it on another computer, This eliminates the possibility that you are trying non-functinal keyboards. That said, it does sound like you have a faulty keyboard controller.

The keyboard controller is part of the motherboard. If this is dead, the correct repair would require a replacement motherboard.

The only alternative connection is USB. Unfortunately, under Windows 95, this isn't a real possibility.

I would recommend that you look for a similar specked computer on the second hand market. You should be surprised how cheaply they can be bought for.

1. Due to wear and tear, the keys for certain characters on a keyboard will wear out. This happens for more commonly used characters. If the problem is due to loose or improper contact, you can try to fix the key back. If this does not work, you can replace the key with a new key purchased from a computer store. Love your keyboard by handling it gentle.

2. Sometimes the keyboard drivers can get corrupted. You need to change them or test the driver.

Go to My Computer :::>Hardware:::>Device Manager and uninstall the keyboard. For windowsXP Start:::>Control panel:::>Keyboard:::>Hardware:::> uninstall keyboard. Restart the computer, the keyboard should get reinstalled automatically.The keyboard should start working again. If not so get keyboard drivers by updating windows or manufacturer web site.

Always use computer or antivirus protection - run a free computer antivirus scan or any other anti-virus since virus can corrupt system files. get one now!

3. Try to swap the keyboard with another keyboard which works properly on another computer. If the alternate keyboard has the same problem, there may be a problem with the keyboard circuit on motherboard.

If the alternate keyboard works properly, check if the keyboard cable is properly connected, whether wires in the keyboard cable are connected properly.

4. Open out the keyboard and check if the keyboard fuse is working. If the fuse has blown, replace it with another fuse of the same rating and size.

5. If you spill water or any liquid on the keyboard, switch off the computer immediately. Unplug the keyboard, turn the keyboard upside down and keep it out for drying either in the sun or under a fan. If some other sticky fluid has been spilled on the keyboard, use a moist cotton swab or ear bud to clean computer or wipe away the fluid. Only when it is completely dry, (it will take a minimum of 24 hours depending on the weather), connect the keyboard back to your computer.

6. For USB keyboard change the USB ports or unplug the keyboard from the USB port then plug it back until it responds or detected. Usually the keyboard led(indicator) lighting up should show a successful connection.

7. Set the speed of character repeatation. For windowsXP Start:::>Control panel:::>Keyboard:::>Speed:::>make adjustments.

8. Set the blinking rate of cursor. For windowsXP Start:::>Control panel:::>Keyboard:::>Speed:::>make adjustments.

9. Go for a typing course or tutorial on how to use keboard features.

10. For discolouration or fading of white keyboard. Use good computer cleaners,soft cloth, whiteners or vinegar mixed with water to keep the original white colour or clean. don't use bleach or rough material to clean. disconnect the power supply. switching to good black keyboard can comfort you.

Computer Memory Problems

Computer Memory Problems

When computer memory problems arises most of us are left bewildered, though the importance of it for our computer system is known to all of us. We get confused as what course of action must be followed or taken to sort out that problem. Effective troubleshooting is the solution to such problems; a practical approach is to follow some simple steps and know the real problem and fix them.Computer memory is also called as RAM (Random Access Memory). This is the temporary location where computer stores information. When you shut down your PC or close down the program, the RAM gets emptied. People often get confused with RAM and Hard Drive, which is the permanent storage of the computer.

Nonetheless, it seems tempting to eliminate a few steps, but at times it may also extend the process of troubleshooting, even more.

1. It would be a good idea to keep a backup of your data immediately if your computer is bootable yet unstable. Data corruption is a common computer problem that may lead to loss of data when you are doing the troubleshooting.

2. System configuration and hardware needs to be checked. In case you have installed the computer memory recently, it is advisable to ensure if the newly installed memory modules are compatible to the system board of your computer and have been installed in the right slots. Confirm that the components of your system match with your documentation and also check the part numbers. Now check the BIOS documentation and motherboard to verify if there is a need to allow any specific settings before the memory is upgraded.

3. Examine the memory modules and system board for any damage and install them back. While the modules have been removed, use a soft cloth to cleanse its contacts by employing the “FluxOff” cleaner. PC vacuum and compressed air can be used to remove the dust from memory socket. After the modules have been reinserted, ensure that their heights are the same to make sure that the replacement is done correctly.

4. Swapping the positions or replacing or reinstalling of the memory modules of the computer is helpful in analyzing if issue is the socket or bad module.

5. The BIOS of the system must be upgraded to solve some computer memory problems. This will resolve compatibility issues, refresh information of the system, and provide in-depth information for troubleshooting.

6. Run good, authentic and updated antivirus software. This may help you to trap some malicious memory programs that might have taken to be RAM problems in the computer.

7. Try to find out any additional causes, if any. Following the above mentioned troubleshooting steps will help you out the fault, if there is any in the computer memory. Failed power supplies, faulty motherboards, deterioration of hard drives and the environmental issues may also cause computer memory problem. So, one must search alternate sources for data loss, instabilities and system crashes.

Repair RAM

First, find the manufacturer and the part number of the module. A small white label should be affixed to the module which includes the part number, nd the manufacturer's
