Fix the new CPU black screen and no beep problem

After installing a new CPU, it may be bothersome if you encounter a black screen problem. Typically, motherboards will emit beeps to indicate hardware problems, and these are called beep codes. However, sometimes things can be different. This article will introduce how to solve the black screen problem caused by the new CPU without the beep sound.

Fix the new CPU black screen and no beep problem

If your new CPU has no beeps and black screen issue on startup, please use the following fix steps. Before performing the repair, please confirm that your CPU is compatible with the motherboard. If the hardware is incompatible, such as CPU or RAM, it may cause startup or boot failures.

Check your basic connection

Reseat RAM, CPU and graphics card

Clear CMOS code

Are any LED indicators on?

Flash your BIOS

let us start.

1] Check your basic connection

It should be noted that a new CPU black screen problem may occur due to improper cable connection. Make sure that all power cables are properly connected to components such as motherboard, CPU, graphics card, etc. Also check that the power supply unit is turned on. Also, make sure the monitor is properly connected to the graphics card or motherboard port. If the problem persists, you can try using a different cable or monitor to troubleshoot the monitor issue.

2]Reseat RAM, CPU and graphics card

We recommend that you re-plug and unplug the RAM. Remove and reinsert the RAM module, making sure it slots correctly and is inserted into place. Check your motherboard manual to find the correct location. For multiple RAMs, remove and reinsert them one by one.

Carefully remove and reinsert the CPU, ensuring proper alignment and installation. Check for bent pins or cracked connectors to confirm there is no obvious damage and replace if necessary.

In order to ensure a reliable connection of the dedicated graphics card, it should be firmly placed into the slot and re-plugged to ensure full insertion and correct contact with the slot pins.

3]Clear CMOS value

Clearing cmos can solve the black screen problem of the new CPU and restore the BIOS default settings. If misconfiguring the BIOS causes a black screen, resetting the BIOS to default values ​​can solve the problem.

You can reset the BIOS settings to their default values ​​by removing and reinserting the cmos battery. Cmos battery is a small coin-based battery.

To clear the cmos battery, you must open the computer case. Turn off the computer and disconnect the power cord to avoid electric shock.

Find the cmos battery on the motherboard, remove it, and wait a few minutes. This will reset the BIOS to its default settings. Reinsert the battery and try starting again.

Also, please pay attention to the direction of and - on the battery. Use a medium flat-blade screwdriver to gently pry the battery away from the connector.

4] Are any LED lights on?

The motherboard also has different LED indicators, including CPU, DRAM, VGA and BOOT. When a problem is detected, the motherboard lights up the corresponding LED indicator. For example, if a memory problem is detected, the DRAM LED lights up.

Check whether the LED indicator on the motherboard is on. If so, you need to troubleshoot accordingly.

4]Flash your BIOS

After installing the CPU, you may need to install the latest BIOS update. To do this, you can flash your BIOS with the help of a USB flash drive. To do this you need the following:

• A working computer
• USB flash drive

You need to download the latest version of BIOS from the computer manufacturer's official website and then copy it to a USB flash drive in the desired format. The general steps to flash the BIOS are as follows:

• Download the latest version of BIOS.
• Copy it to the USB flash drive in the correct format. The USB flash drive should be empty before copying the BIOS. Additionally, the file system of the USB flash drive should be FAT32. If the file system of the USB flash drive is NTFS, change it to FAT32 by formatting the USB flash drive.
• After copying the BIOS to the USB flash drive, plug it into the motherboard's dedicated USB port. This USB port is used to flash the BIOS (see user manual).
• Now, connect the power supply to the motherboard and press the dedicated button on the motherboard.

When you press the button, the LED will start flashing. This means that the process of flashing the BIOS begins. The light keeps blinking until the BIOS is updated to the latest version. After starting the process, do not interrupt the process. Interrupting this process may corrupt your BIOS. This process can take up to 10 minutes. Once the BIOS update is complete, the LED will stop flashing.

Above, we have explained the general process of flashing the BIOS. We recommend that you refer to the user manual for the correct procedure for updating the BIOS without CPU or RAM. Following incorrect procedures may damage the motherboard.

We also recommend that you do not download the beta version for flashing the BIOS (if available) as it may contain bugs and cause motherboard failure.

Why is my CPU running but a black screen appears?

There may be several reasons why your CPU is running a black screen. Some of the most common causes are incorrect connections, hardware issues, corrupt graphics drivers, incorrect BIOS settings, etc. To resolve this issue, clear CMOS to reset BIOS settings, reseat the CPU, check power connections, etc.

Why can’t my computer start self-test and there is no beep sound?

Sometimes, a faulty power supply unit (PSU) fails to provide adequate or stable power to the components, causing the components to not function properly and resulting in no POST beeps. When the power supply is insufficient or the power flow is interrupted frequently, your computer fails to initiate any beeps. Go check the power cord and PSU to see if they are working properly.
