Diagnosing Computer Components After a Power Supply Failure

Experiencing a power supply failure can be a frustrating situation for any computer user, especially when it follows a power surge. If you’ve recently found yourself in a similar predicament, where your power supply abruptly stopped functioning—resulting in unexpected shutdowns and even a burning smell—you’re likely concerned about the health of the other components in your system. Here’s a comprehensive guide on how to test your hardware to ensure everything is functioning smoothly.

Understanding the Situation

After experiencing a power surge, particularly when using a surge protector, it can be alarming to have your power supply unit (PSU) fail. The abrupt shutdowns under heavy load could indicate that something went seriously wrong, and the burnt odor could signal possible damage to other components. The good news is that you can take proactive steps to assess the health of your CPU, RAM, and storage devices.

Tools and Techniques for Testing Components

Before you take any additional steps, it’s essential to replace the faulty power supply with a new one—this should be your first course of action. Once you have the new PSU installed, here are some methods to evaluate the condition of your computer’s other components:

1. Running Stress Tests

One effective way to check your CPU and RAM health is through stress testing. Utilities like Prime95 or AIDA64 can put your CPU under heavy load to see if it maintains stability without crashing. However, since you experienced shutdowns during a previous stress test, monitor the temperatures and system performance closely this time around.

2. Diagnostic Software

There are several utilities available that can help you evaluate the health of your components:

• CPU-Z: This tool provides detailed information about your CPU, motherboard, and RAM, allowing you to verify specifications and check for any anomalies.
• HWiNFO: This comprehensive hardware analysis tool can also deliver real-time temperatures, voltages, and loads, offering insights into the performance and health of your components.
• CrystalDiskInfo: To assess your hard drives and SSDs, use this utility to check the S.M.A.R.T. data for any potential issues that could indicate failing hardware.

3. Performing Check Disk

Since you’ve already run the chkdsk utility and received positive results, that’s a good indication that your storage is likely still intact. However, if you suspect issues, you can
