How to Fix: Anyone know how I can fix my pc?

PC won't boot after new case upgrade, only RAM lights up and fans spin briefly.


The error you're experiencing is likely due to a faulty power supply unit (PSU) or an issue with the motherboard's RAM slots. When you upgraded to a new case, it's possible that the PSU was not properly seated or connected, causing the system to malfunction. The fact that your PSU works when jump-started suggests that the issue lies within the system itself.

⚠️ Common Causes

  • Faulty PSU or loose connections
  • RAM slot issues, such as a faulty slot or bent pins
  • Motherboard compatibility problems with the new case

🛠️ Step-by-Step Verified Fixes

Method 1: PSU Reset

  1. Step 1: Unplug the power cord and any other cables from the back of the PC.
  2. Step 2: Press and hold the reset button on the PSU for at least 10 seconds to discharge any residual power.
  3. Step 3: Reconnect all cables and plug in the power cord, then press the power button to test the system.

Method 2: RAM Slot Cleaning

  1. Step 1: Remove the RAM modules from their slots and gently clean the contact points with a soft brush or cotton swab.
  2. Step 2: Reinsert the RAM modules into their original slots, ensuring they are securely seated.

Method 3: Motherboard Testing

  1. Step 1: Remove the motherboard from the case and inspect it for any signs of physical damage or burn marks.
  2. Step 2: Use a multimeter to test the motherboard's RAM slots and power connectors for any signs of malfunction.

💡 Conclusion

If none of these methods resolve the issue, it may be necessary to seek further assistance from a professional or consider replacing the PSU and/or motherboard. Don't hesitate to try each method before seeking help, as they are designed to be safe and effective.
