Many of the common computer problems like the blue screen or slow computer are due to defective computer memory - Random Access Memory (RAM). Some of the problems can be fixed yourself but in a few cases you may have to either replace or upgrade the memory.
How to troubleshoot and fix computer memory problems
1. Most problems are caused by incorrect installation of RAM. The memory modules should be fixed securely in the memory slot. They should be aligned properly with the notches in the slot. The retaining clips should be fitted properly. Memory modules inserted backward will cause permanent damage to both the memory module and motherboard.
2. If new memory (RAM modules) have been installed , check if the specifications match that of the RAM currently installed. For some motherboards, only identical memory modules can be installed in adjacent slots of a motherboard.
3. Check the computer manual and installation instructions of the memory being used. If there even a small problem in RAM installation, there could be errors
4. Remove the memory and again reset it. The problem may be due to loose contact and resetting will solve the problem.
5.Most memory banks have at least 2 slots for fitting memory modules. Try installing the memory module in another slot, it may start working.
6. Try installing some other memory module in the same slot. If the new memory module works, the old memory module is defective.
7. Sometimes if the computer power supplies are not outputting enough power, the memory bus may not receive enough power. So check if the power supply is working properly.
