Usually, this problem can be caused by different factors. The first is having installed RAM that is not compatible with the ones we already have installed. An incorrect installation or even the BIOS not detecting it for whatever reason is also common.
We are going to explain all the actions you can do to solve the problem with RAM memory. We will go little by little, explaining all the steps to be taken.
Check RAM compatibility
The first thing you should do after installing new system memory and the screen goes black is uninstall the new RAM. If the computer turns on, then there is some kind of compatibility problem. This is normal, especially if the characteristics of the system memories have not been verified before.
We are going to quickly explain how to see the specifications of the memory we have installed. We can do this like this:
- Download the CPU-Z software from the official website.
- Start this program and go to the “SPD” tab.
- Now the values ”Max Brandwith”, “Module Manuf”, “Ranks”, “CAS Latency”, “RAS to CAS”, “RAS Precharge” “tRAS” and “tRC”, as well as “Voltage”.
Now we turn off the computer, uninstall the old RAM and install the new modules. If the computer turns on, we must verify the characteristics of the new RAM. To do this we will reopen CPU-Z and access the SPD tab.
If any of the parameters differ, the computer will not start, since it detects different modules and if there are discrepancies, to “protect itself”, it does not start. Return the modules and look for memory from the same manufacturer that matches the specifications of the RAM you already had installed.
Make a Clear CMOS
Performing a CMOS erase process can help fix the problem. What this process does is reset the BIOS to return to its basic configuration. This could solve the problem quickly and easily. To carry out this process, we must follow these steps:
- Turn off the computer and disconnect it from the power
- Look on the motherboard for the CMOS battery, which is the size of a coin.
- Now, we must remove it being careful not to damage the motherboard
- Press the computer’s power button for 30 seconds to speed up the process.
- Replace the battery taking into account the polarity.
- Finally, connect the power and try to boot the system.
If the problem has been solved, that’s it, we shouldn’t have to do much more. If the problem persists, we must carry out the following process. Some motherboards do not require the battery to be removed; they usually have a jumper nearby to do this process.
Update the BIOS
The problem may persist and then we will have to perform a much more specific task such as updating the BIOS. This process is slightly complex, but following the steps you will have no problems:
- You must have access to another computer to download the latest version of the BIOS. It is necessary to know the manufacturer and model of the motherboard, something that we will find in the manual.
- Connect a USB flash drive or any other external storage drive.
- You have to format the drive, you need to set the FAT 32 format.
- We download the new BIOS and copy the file to the external storage drive.
- Install the USB storage drive into the USB port dedicated to updating the BIOS. To do this, we must consult the user manual.
- Now, we have to press the button to update the BIOS or the power button on the computer.
Motherboard manufacturers specify in the manual how to carry out this process correctly. If you have questions, look it up in the manual.
Specialized support
If, at this point, your problem persists, you will need to go to a nearby computer store. There they will carry out a more in-depth verification and will be able to better detect what is wrong.
You may be afraid to update the BIOS so as not to mess it up, but you should know that this can also be done for you in a specialized store. You simply have to bring them the equipment, explain what tests you have performed and then they will know better what measures to take.
