Motherboard Problem Check
Once your system is powered on, the next question is whether or not the motherboard’s speakers emit an audible beep. If your computer’s motherboard doesn’t have built-in piezoelectric speakers but provides speaker ports close to the power connection and reset (often found in the front and left corner), you can connect external case speakers.
If you find a continuous series of beeps, this may indicate faulty RAM, while the repetitive pattern could be caused by a problem with the RAM or video components. Whether or not there is an audible signal, make sure to correctly reposition the video adapter and RAM, paying particular attention to the locking mechanism on the memory socket.
Disassembling the device is the next stage in situations where the device cannot be turned on. Before making any changes to the case, it is recommended to disconnect the power cord. It’s a good idea to disconnect the drives one at a time, then reconnect the power and try turning them back on. To accurately determine the faulty component, systematically disconnect all adapters except the video adapter, and restart the device each time you remove it. Be sure to restore the power supply each time before trying again.
Whether the computer works fine when turned on, produces one or two beep sounds, but in the end, it gets stuck on the BIOS display. This issue may occur when in the middle of memory enumeration, during or after a drive scan, or during the “Verifying DMI Data Pool” phase, particularly on a text screen. The root of the problem is very likely to be a clash, especially between adapters, but it may also be between incompatible drives sharing the bus.
Simplify the system into its basic components, including the power supply, motherboard, CPU, minimum RAM, heat sink, and video adapter. If the system does not freeze after simplifying, but instead reports problems booting, proceed to Conflict Resolution.
The right advice is to change the position of the RAM, reset the bank if there is more than one, or move a single module to an adjacent slot. If the freeze persists, consider testing the RAM with known compatible RAM from a different system.
Using RAM that does not meet the specifications set by the motherboard manufacturer is not recommended, although it works fine so far. Choosing inappropriate RAM can result in problems that vary from system failures to sporadic crashes.
Although it is not certain that replacing RAM at this stage can solve the problem, it is advisable to consider this option. You should not throw away the RAM that you have removed, because it could still function in the future.
Consider resetting all CMOS settings to their default configurations unless you have already done so. Typically, resetting these settings can be done through prominent options within the CMOS menu, such as “Restore Default Settings” or “BIOS Default Settings.”
When restored to default settings, the system will automatically detect and optimize RAM specifications according to the recommended time. If you have overclocked, it is recommended to stop the process until the system returns to normal. Regardless of whether your computer successfully overclocks the same CPU or RAM, going beyond the manufacturer’s recommendations is risky.
Too high a temperature will quickly cause the system to become unresponsive. Remove the current heat sink and fan, check that the fan is functioning normally, and make sure that the design of the bottom of the heat sink allows full contact with the CPU. Before reinstalling the heat sink, it is recommended to use thermal tape or an authorized lubricant. Excessive use of thermal grease should be avoided so as not to cause new problems. The sole purpose of the thermal medium is to occupy a small space between the mold surface and the heat sink.
Make sure the cooling fan attached to the heat sink starts operating after the power is turned on. If this problem persists even after connecting to the correct power source according to the motherboard manual, consider replacing the inactive cooling unit with a new one.
