Computer Memory ProblemsComputer Memory Problems
How to Fix Them
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.

Most of the monitors normally include an activity light in their front which is automatically turned on as soon as the computer is switched on. However, if the monitor fails to blink the green light, it will not get turned on thus, indicating that the monitor is not able to receive any power. An individual can easily tackle this problem by checking whether the monitor plug is properly attached to the main power switch or not. · Another computer monitor problem is that the lights are turned on, yet the monitor fails to work and connect with the power switch. In such situations where the green light is turned on but the monitor is not able to depict any images on the screen, it is better to check the resolution settings. It could be possible that the brightness and contrast settings were accidentally changed, thus turning the screen pitch dark. · Poor picture quality is yet another common PC monitor problem which may seem frivolous but can actually hamper the user’s performance. The image on the screen may appear blurry or distorted at times. This problem can be easily treated by restoring the default settings of the screen resolution. Some computer screens are not able to clearly represent images which have a relatively higher screen resolution. In such situations, it is better to check the resolution settings once again so that the monitor can clearly depict the image. · Another common monitor problem is that individuals do not take care of the safety instructions and end up cleaning the surface of the screen with liquid detergents which may harm the monitor again. It is better to use a dry cloth to clean the monitor screen and steer clear from liquid cleaners.If it s genuine hardware problem of the monitor then it is bit hard to fix at home. Only specialized technicians can repair these problems

Here are common keyboard problems and how to prevent or fix them. Just as the computer software needs to be maintained for efficient functioning, similarly computer hardware too requires adequate amount of care to keep working properly. Taking care of the monitors and the CPU is relatively easier, than tackling computer keyboard problems. It is so because there are lots of keys with individual connection points in the keyboard that makes it a little tougher to clean. The most common keyboard problem of computers is “keyboard not found” message at the start-up. This means the computer cannot detect the keyboard. The reasons for this problem can be 1.Keyboard is not plugged-in properly To resolve this switch-off the PC, Plug the keyboard properly and restart the computer. 2.Pins of the keyboard connector have damaged. This often occurs when you try to plug the keyboard and force without properly matching positions of keyboard pins with the holes in the computer. If the pins are not broken you can use a tiny screwdriver or similar equipment and carefully straighten affected pins. Shut down the PC and plug-in the keyboard again carefully and restart. If the computer keyboard is not taken proper care of, then it may start malfunctioning and may even become dysfunctional after some point of time.

To combat that problem, you can use the contact cleaner (electronics- grade) on the affected key switches. You may never know when you may accidentally drop the keyboard off the table or yank/tug on its cord, and the connectors and cables may get loosened. To escape having error messages while booting because of the loosened connectors and cables, always check them thoroughly before starting the computer.If you want to keep simple computer keyboard problems away or keep keyboard as good as new, you can also get it laminated by a thin plastic sheet or you may keep it covered when not in use.
