Defective memory manifests itself through random crashes or bluescreens. In the worst case, the computer can no longer be booted at all. So, if you have come across a defective RAM module, z.b. with the Windows memory diagnostics under Windows 7 or an external tool like z.b. Memtest, then you should immediately arrange for a replacement and replace the defective memory module.
In the manual of the mainboard on the Internet you can easily find out what type of memory you need.
Removing the defective RAM
First, of course, switch off the computer and disconnect it from the mains. Safety first. Then you open the case, usually it is enough to open a side panel. You now have a clear view of the computer’s hardware components. Maybe also a good opportunity to remove the dust that accumulates in this way.
As you can see, the sockets with the RAM modules are easy to spot. In my case only one module is installed. If several memory modules are installed, then the computer must be operated alternately with one module at a time and the RAM test must be repeated. Only in this way can you be sure to replace the right memory module.
The RAM is held in the socket on the left and right with a small retaining clip. These two brackets have to be opened first. Then you can pull the RAM module(s) out of the socket.
Install new RAM
When installing the new memory, make sure that the memory is inserted the right way round. Of course you can see at first sight that the side with the contacts belongs downwards, but you can still insert the modules twisted.
To prevent this from happening, and to prevent the wrong type of RAM from being installed, there is a notch in the side with the connection contacts. A suitable counterpart can be found in the socket on the mainboard. So the module fits into the socket only in one direction.
The actual installation of the new RAM is then totally simple:
Insert the RAM module into the socket according to the notch and push it straight downwards. The two retaining clips on the left and right close automatically and hold the module securely in the socket. An additional configuration or changing the settings is not necessary in 99% of the cases, because the mainboard automatically detects the memory and configures it correctly.
After reassembling everything and turning on the computer, you should already be able to see if the correct amount of memory is displayed when the computer boots up.
Finally, you can check under Windows if the correct size of the RAM is displayed and thus all memory modules are working properly. If this is the case, crashes and error messages due to defective memory are a thing of the past.
