• Power On and Test: Turn on your computer and observe if the problem persists. If the issue disappears, the original PSU is the likely cause. If the problem persists, the issue might lie elsewhere.

If the issue does not exist with the replacement PSU, then the original Zalman PSU may be the cause of the problem, so it might need to be replaced.

Step 3: Component Testing

If you don't have another PSU available, or the issue persists after replacing the PSU, it's time to check other components.

• RAM: Test the RAM sticks one by one, using different slots on the motherboard. This can help rule out faulty RAM as the source of the problem. Remove one stick of RAM at a time and try booting the computer.
• Graphics Card: Remove the graphics card and try booting the computer using the integrated graphics (if available). This is helpful when the PC won't boot or restarts frequently during graphically intensive tasks.
• Motherboard: Check all connections on the motherboard, including the CPU power connector. It is very easy to overlook simple solutions such as these.
• Hard Drive/SSD: Disconnect any secondary storage devices and see if the problem persists. Check the boot drive with diagnostics tools. Ensure that the storage drive is not causing issues with booting.

This step helps you isolate if the issue is with a specific component. If these steps don't solve the problem, then it is most likely a PSU issue.

Step 4: Using a Multimeter

For those comfortable with electronics, a multimeter can help you verify the PSU's voltage outputs.

• Safety First: Ensure the PSU is disconnected from power and that you understand how to use a multimeter safely. Incorrect use can be dangerous.
• Voltage Testing: Consult the PSU's specifications to determine the correct voltage outputs. Usually, these are +3.3V, +5V, and +12V. You can test the voltage at the connector pins using a multimeter. The voltages should be within a certain tolerance. Check your PSU's specifications for the exact values.
• Analyze the Results: If the voltages are significantly off, the PSU is likely failing. A multimeter is a helpful tool for finding out if the PSU is providing power at the right levels.

This is a more advanced step, and should only be performed if you're comfortable with electrical equipment.
