Hi Brainy! It is most likely your PSU (Power supply) You still should:
- Check the Power Supply:
- Power Cable and Outlet: Ensure the power cable is securely plugged in and test the outlet with another device to confirm it’s working.
- Power Supply Unit (PSU): The sound you heard might indicate a PSU failure, especially if there was a pop or a burning smell. This can happen due to a power surge or component failure. Consider testing the PSU with a multimeter or swapping it with a known working one if you have access to one.
- Inspect for Visible Damage:
- Open the case and look for signs of burnt components, particularly around the PSU and motherboard. Swollen capacitors or burnt marks indicate a likely point of failure.
- Perform a Basic Power Reset:
- Disconnect the power cable and hold down the power button for about 15 seconds to discharge any residual power. Then, reconnect the cable and try turning it on again.
- Motherboard Diagnostics:
- Check if there are any diagnostic lights or error codes flashing on the motherboard when you try to power it on. Some HP desktops have diagnostic LEDs or beep codes that can indicate specific issues.
- If the PSU appears functional but the system still won’t turn on, the motherboard itself may have failed.
If none of these steps help, the most likely culprits are a failed PSU or motherboard.
