What is RAM
Random Access Memory(RAM) is a way for your computer to store temporary data that it is likely to need soon. Other ways that computers store data are through a cache or storage. Storage, often wrongly referred to as memory, is permanent data stored on a hard drive or solid state drive. A CPU cache is a small amount of memory that is stored right on the CPU chip. The cache is for data that is used very frequently. Both the RAM and CPU cache are temporary data stores that are cleared when your computer is turned off.
Memory problems are less common than many other computer problems because memory sticks have no moving parts so have fewer points of failure. However, due to this many RAM problems are misdiagnosed. Memory usually will last longer than other computer components so manufacturers offer warranties longer than most other computer parts. If you buy brand name memory it will likely have a lifetime warranty
Symptoms of a RAM problem
- . You turn on your computer and it runs fine. You go about your normal tasks and notice that your computer performance decreases. By lunch time the load times of a typical website seem to be measured in minutes. Does the problem occur not just with internet websites, but also with running local programs? This type of gradual deterioration of PC performance, especially with memory intensive programs, may be caused by a RAM problem.
- Does your computer restart randomly when you are in the middle of something? Your computer may just have booted and begins to load your desktop and then immediately reboots. It may freeze up sporadically. This could be a sign of faulty RAM.
- Your screen flashes a blue screen with white text before restarting. Blue Screen errors can be one of the most annoying things to happen to your computer because you don't have a chance to read the error message. Many things can cause this problem and bad memory is one of them.
- Have you found that files are randomly corrupted? This may happen with files that you frequently access and save. RAM issues can cause this problem or worse. The file structure of your hard drive may slowly go downhill and become unbootable.
- Your attempts to install a new program repeatedly fail for an unknown reason. Could be a RAM problem. You try to reinstall the operating system, but keep getting odd error messages. If this follows number four above, it is almost a sure sign of bad memory.
Other possible causes of problem
• A hard drive problem can cause many of the symptoms listed above. You can run a utility called CHKDSK by pressing the windows button and the “R” button at the same time and then typing CHKDSK and pressing enter. Alternatively, you can click on Computer, right click the drive you intend to scan, click Properties, then the Tools tab, and click Check now. Note you will need to restart your computer. Also, be aware this may take an extended amount of time to finish running. If you hear your hard drive making lots of noise during normal operation, it may be the cause of the problems. Defragmenting your drive every few months is a good idea as well.
• One additional cause could be a virus. Note that many people automatically assume any problem with their computer is caused by a virus. Many large retail repair stores frequently misdiagnose problems as viruses as well. Make sure you have a good anti-virus program and be sure to run scans on a regular basis.
Checking and Verifying RAM Problems
- First, we need to open the side cover of your computer. To learn the right procedure and the safety precautions,
- Have your computer AVR turn off and the system power cable detached. Locate where the RAM modules are. Remove then by gently pressing down the notch handles on the sides of the RAM socket.
- Turn your computer on. There should be a continuous beeping. This is normal as it is a computer’s way of saying that the RAM(s) is missing. Now turn your computer off with the power cable unplugged (because there is a standby power of 5V in the system), put back the RAM to the first slot (nearest to where the CPU is located).
- Turn your computer back on. If you will still hear a continuous beeping sound, then that would mean that your RAM is defective or your slot may be defective or dirty. To check this, just remove the RAM for the first slot and put it in the second slot. Turn on the system unit and observe. If the beeping sound is gone, then your slot may be dirty or defective. If you got more than 1 RAM, individually check the RAM to test on the slots.
After you have confirmed which RAM or slot is defective, we need to do some fixes. Normally if a RAM is defective, we just have to replace it with a new module.. So here are some things you can do to make some simple fixes.
Cleaning The RAM
1. Get a rubber eraser and a small paintbrush.
2. Rest the RAM on the table or any clean flat surface with your fingers supporting the RAM on the sides.
3. Gently rub the eraser on the gold colored edges until it is clear and brilliant.
4. Brush the shredding with a paint brush.
5. Clean the other side of the RAM.
6. In some instances grime like substances accumulate in the gold edges of the RAM, this can be removed by spraying it with an instrument detergent.
Cleaning the Memory Slot
1. Memory slots can hardly be cleaned. That’s why it is coated with gold just like the edges of the RAM to protect is against tarnishing. Simple brushing the slots can and will clean it effectively.
2. The second is a method of cleaning the RAM slot is to use a piece of flat plastic (an old unused credit card will do) and a piece of paper. Fold the paper around the credit card and plug it in the ram slots. Brush the slot after the cleanup.
