Q: How to connect and use the Power LED on the ASROCK X570 Steel Legend motherboard?

The Power LED (system power LED) on the ASROCK X570 Steel Legend motherboard is a small indicator light connected to your case that shows the power status of your PC. On this motherboard, the Power LED connector can be found in two possible locations: the PANEL1 (System Panel Header) connector or the SPK_PLED1 (Power LED and Speaker Header, 7 pins) connector. Check your case to determine which type of connector it uses. To connect the Power LED, locate the PLED+ (positive) and PLED- (negative) pins on the motherboard's panel connector. Plug the cable from your case's LED into these two pins, strictly observing the polarity: the positive wire (usually red or white) should go to PLED+ , and the negative wire (usually black) to PLED- . Note: these are not jumpers but connectors. Never place a jumper cap on these pins. Once properly connected, your Power LED will have three behaviors: it lights up continuously when the system is functioning normally, it blinks slowly when the system is in S1 or S3 sleep mode, and it remains off in deep sleep S4 mode or when the PC is completely powered off. This behavior is automatic and requires no BIOS settings. If your Power LED does not work despite a correct connection, first check that the cable is securely plugged into the pins. Then, confirm that the polarity is correct by reversing if necessary (although this may damage the LED in the long term if reversed). If the LED remains off, check that the power supply is actually reaching the motherboard by ensuring that the fans and other indicators are working. If only the Power LED does not work, the LED itself may be defective and needs to be replaced.

Question 1

Why is my ASRock Z270 Pro4 motherboard not producing video output?

Accepted Answer

The ASRock Z270 Pro4 motherboard is equipped with three video connectors: D-Sub, DVI-D, and HDMI. If you have no display, start by checking that your monitor cable is plugged into one of these three ports located at the back of the motherboard, and not into a port of a discrete graphics card.

Essential prerequisites: The video outputs of the Z270 Pro4 only work with Intel 6th or 7th generation processors (Skylake or Kaby Lake) equipped with integrated graphics. Ensure that your processor has an integrated GPU such as Intel HD Graphics or Intel Iris; otherwise, you need to use a discrete graphics card.

Troubleshooting steps: Start by checking that the 24-pin ATX power connector is properly plugged into the motherboard. Then access the BIOS by restarting and pressing Delete or F2, then look for the integrated graphics option (usually in the Chipset or Graphics menu) and make sure it is enabled. If you have a discrete graphics card installed, temporarily remove it to isolate the issue and test directly with the motherboard's integrated graphics.

Connector specifications: The HDMI port supports a resolution up to 4K x 2K (4096 x 2160), while the D-Sub and DVI-D ports support a maximum resolution of 1920 x 1200 at 60 Hz. Test each connector in succession with your monitor.

If after these checks you still have no video signal, test your monitor on another device to rule out a defect in the monitor itself. You can also reset the BIOS by removing the CMOS battery for a few seconds (see the CLRMOS1 connector on the motherboard) to restore the default settings.

Question 5

What should I do if my PC with an ASROCK H87M motherboard makes a loud noise and then does not turn on despite being powered?

Accepted Answer

If your PC with an ASROCK H87M motherboard made a loud noise at startup and then does not turn on, this generally indicates a detectable hardware problem. Here are the steps to diagnose and resolve this issue:

Step 1: Visual inspection and checking connections

Before any intervention, completely turn off your PC and unplug the power cable. Wait 30 seconds. Visually inspect the ASROCK H87M motherboard for any apparent damage: swollen or exploded capacitors (the solid design should ensure their integrity), burn marks, or blackened components. Then check that all power connectors are properly seated: the 24-pin ATX connector (number 6 on the board) and the 12V 8-pin connector (number 1) must be securely in place.

Step 2: Reset the CMOS

The loud noise followed by the failure to start may result from corrupted BIOS settings. To reset the CMOS, do the following: turn off the computer and unplug it. Wait 15 seconds. Locate the CLRCMOS1 jumper on the board (position 14 according to the documentation). Use a jumper cap to short pins 2 and 3 for exactly 5 seconds. Reposition the jumper to its default position and wait 30 seconds before plugging back in and restarting.

Step 3: Check the RAM

Completely shut down the PC and unplug it from the power source.
Remove the RAM modules from both DDR3 slots (the H87M board has 2).
Gently clean the gold contacts with a soft cloth or a 99% white eraser.
Reinsert one module first, fully seated until it clicks, then attempt to start.
If the PC starts with this module, test the other module alone. If one module causes the problem, it is defective.
If the PC starts with the RAM, you have identified the problem. If no module works, proceed to the next step.

Step 4: Check the power supply

The 24-pin power connector may be poorly inserted or the power supply may be faulty. Even with a power indicator, a power supply can provide unstable voltages that trigger protections and a safety noise. Try with another compatible power supply (same wattage or higher) if available, especially a reputable brand power supply compliant with the ErP/EuP standards required by your board.

Step 5: Check the CPU connectors

You generally cannot reinsert a processor safely without specialized tools, but check that the CPU cooler is properly closed and that the 8-pin 12V connector for CPU power is securely connected. A poorly seated processor or missing CPU power can also trigger the noise.

Step 6: Isolate optional components

Remove the dedicated graphics card if you have one (test with the integrated graphics of the 4th generation Intel processor). Unplug additional fans, hard drives (keep only the CPU power and RAM) and test minimally. Sometimes, a blocked fan or a short circuit on an optional connector causes the noise.

If after these steps the PC still does not start or makes the noise again, it is likely that the H87M motherboard or the processor is damaged. In this case, professional repair or replacement of the defective component will be necessary. Please consult the ASRock support page to check the warranty coverage of your board.

Question 6

What should I do if my PC with an ASROCK H87M motherboard no longer gives any video signal?

Accepted Answer

Your ASROCK H87M motherboard has two video connectors: a D-Sub (VGA) port and an HDMI port. If your PC no longer gives any video signal, start by checking the video output cables - make sure the video cable (HDMI or D-Sub) is properly connected to both the motherboard and the monitor. Test with the other available video port if possible, and check that the monitor is turned on and set to the correct input.

Next, disassemble your PC and tighten the internal connections: turn off the computer, unplug the power cable, then check that the 24-pin power cable and the 8-pin CPU cable (4+4) are properly connected to the motherboard. Also, reinsert the RAM by removing it and then firmly putting it back into both DIMM slots, as a poor RAM contact is a common cause of no video display.

If your processor does not have integrated Intel HD Graphics, you will definitely need a dedicated graphics card in the PCIe x16 slot. The H87M can only produce video through its native ports (D-Sub and HDMI) with compatible 4th generation Intel processors that have integrated HD Graphics.

Then perform a BIOS reset: with the PC completely off and unplugged, wait 15 seconds, then locate the CLRCMOS1 jumper on the motherboard. Position the jumper on pins 2-3 for 5 seconds to reset the BIOS to default settings. This can resolve video compatibility issues due to incorrect settings.

Also observe the LEDs and startup beeps: the power LED (PLED) should light up once the PC is powered on. Listen for the beep sequences at startup, which may indicate a diagnostic code. If you hear 5 repeated beeps, this usually indicates a RAM or missing graphics card problem.

Finally, check that your power supply delivers enough power - the H87M requires a 24-pin ATX connector and an 8-pin connector for the CPU. If all these checks do not resolve the issue and you see no signs of life (no LEDs, no fans), it is likely a hardware failure requiring specialized technical intervention.
