Does your computer turns on but no display? There is nothing frustrating than seeing your beloved computer not coming to life when it is needed the most; we understand that. Don’t sweat; you are not the only one experiencing it, and we are here to help you overcome this exasperating issue. Let’ get started.
Fixes for computer turns on but no Display
Check the monitor
First thing first, check whether the monitor that is attached to the computer is properly working or not. Perhaps you are facing the issue because of a faulty monitor. First, check the power-on indicator and then the power source. Also, it would be ideal to notice the condition of the monitor with a different device. If you find no issues with the monitor, move on to the next method.
Check the video cable
As you know, the video cable bridges the connection between a computer and a monitor. So, one of the first inspections you have to make is whether the video cable is properly connected to the two devices. Unplug the devices from the power source and reconnect the video cable and check the issue still exists.
In addition, have a close look at the video cable to see any damages and if possible, try using a new cable as well.
Remove all peripherals
There is a possibility of peripherals such as the mouse, keyboard, printer, or USB devices contributing to this issue. So, bring your computer to a kill by disconnecting with the power source. Then, remove all those attachments. Now, connect the computer to power again and press the power button. If you see the monitor works, as usual, it says one or a few peripherals are causing the problem.
In order to identify the exact device, try connecting one at a time to the computer back again.
Remove and reconnect the RAM
This is one of the major reasons for black screens, and reinstalling the RAM often provides the solution. First, switch off the computer and disconnected the computer from the power source. Now open up the case of your computer and remove the RAM/s from the slots. If you don’t know what RAM is, refer to the below image.
Clean the RAM using a dry microfiber piece of cloth and reinstall. Switch on the computer and check the issue; if it is still there, let’s move on to the next step.
Remove and reinstall the CMOS battery
Faulty BIOS settings also have a say on this issue. You can reset the settings by reinstalling the CMOS battery of your computer’s motherboard. After you disconnect the computer from the power supply, open the case of your computer and identify the CMOS battery. This is how it looks.
Now, remove it from the sots using your fingernails. Wait for a couple of minutes and fix the battery again to the motherboard. Power on the computer and inspect the condition.
If the computer turns on but no display issue persists, you can reseat every possible component inside the computer other than the RAM and CMOS battery. However, if you don’t have adequate knowledge about this process, don’t do it, as you would end up with damaged parts.
Alright, what if nothing works for you and your computer is full of valuable data? As far as the issue is not with your hard drive, there is a possibility of retrieving the data from the troublesome computer.
How to retrieve data from a black screen damaged computer?
The simplest option you have is to remove the hard drive from the computer and retrieve the data by using another computer. Also, you can consider a hard drive enclosure to get the job done. However, if you opt for this method, you must purchase the right enclosure to match the model of the hard drive.
The removal of the hard drive might be challenging for those who have no previous experience on the matter. If you fall into that category, it would be best to seek the help of a professional for the task.
When you use the hard drive as an external drive with the help of an enclosure on another computer, it would appear as a normal hard disk. You can access the files again as you did with the erroneous computer.
How to prevent black screen in future?
