Question:

How to troubleshoot a newly built PC that does not show any display output?

I have recently assembled a PC with the following specifications:

• Motherboard: ASUS A620M-A
• GPU: RTX 4070
• CPU: 7700X
• RAM: 32 GB DDR5 5200 MHz
• PSU: 750 W
• Storage: 1 TB NVMe

The PC powers on, but there is no signal on the monitor. I have tried the following steps, but none of them resolved the issue:

• Removing and reinserting the GPU and RAM
• Updating the BIOS using the flashback feature
• Checking all the cables and connections

What could be the cause of this problem and how can I fix it?

Thank

you for your assistance.

Answer:

Building your own PC can be a rewarding and satisfying experience, but it can also come with some challenges and frustrations. One of the most common issues that new PC builders face is the lack of display output when they turn on their machine. This can be caused by a variety of factors, such as faulty hardware, incompatible components, incorrect settings, or loose connections. In this article, we will go over some of the possible causes and solutions for this problem, and help you get your PC up and running.

Check the monitor and the video cable

The first thing you should do is to make sure that your monitor and the video cable that connects it to your PC are working properly. You can do this by testing them with another device, such as a laptop or a console, or by using a different monitor and cable with your PC. If you see a display output with the other device or the other monitor, then you can rule out the monitor and the cable as the source of the problem. However, if you still see no display output, then you may have a faulty monitor or cable, and you should replace them or contact the manufacturer for support.

Check the power supply and the motherboard

The next thing you should do is to check the power supply and the motherboard of your PC. You can do this by looking at the LED lights or the fans on these components. If they are not lit up or spinning, then it means that they are not receiving enough power, or that they are defective. You should make sure that the power supply is connected to a working outlet, and that the power switch on the back of the unit is turned on. You should also make sure that the 24-pin ATX power connector and the 4-pin or 8-pin CPU power connector are firmly plugged into the motherboard. If these connections are loose or missing, then your PC will not boot properly. If the power supply and the motherboard are getting power, but you still see no display output, then you may have a faulty power supply or motherboard, and you should replace them or contact the manufacturer for support.

Check the GPU and the RAM

The third thing you should do is to check the GPU and the RAM of your PC. These are the components that are responsible for generating the graphics and the memory of your system, and they are also the most likely to cause compatibility or installation issues. You should make sure that the GPU and the RAM are compatible with your motherboard and your CPU, and that they are inserted into the correct slots. You should also make sure that they are firmly seated and locked into place, and that they are not damaged or overheating. You can do this by removing and reinserting them, or by trying them in different slots or with different components. If you have more than one GPU or RAM stick, you can also try using only one of them at a time, or swapping them around, to see if any of them are faulty or causing conflicts. If the GPU and the RAM are working properly, but you still see no display output, then you may have a faulty GPU or RAM, and you should replace them or contact the manufacturer for support.

Check the BIOS settings

The fourth thing you should do is to check the BIOS settings of your PC. The BIOS is the basic input/output system that controls the boot process and the hardware configuration of your system, and it can sometimes cause display issues if it is not set up correctly. You can access the BIOS by pressing a certain key, such as F2, F10, or DEL, when you turn on your PC, before the operating system loads. You should look for the settings that relate to the display output, such as the primary display device, the video mode, or the integrated graphics. You should make sure that these settings are compatible with your GPU and your monitor, and that they are not disabled or overridden. You should also look for the option to update the BIOS, which can sometimes fix compatibility or performance issues. If you are not sure how to change the BIOS settings, you should consult the manual of your motherboard or contact the manufacturer for support.

Conclusion

In this article, we have covered some of the possible causes and solutions for the problem of no display output on a newly built PC. We have suggested that you check the monitor and the video cable, the power supply and the motherboard, the GPU and the RAM, and the BIOS settings, and that you replace or contact the manufacturer for any faulty or incompatible components. We hope that this article has helped you troubleshoot and fix your PC, and that you can enjoy your custom-built machine. Thank you for reading.
