Hello! I'm sorry to hear about the issue with your PC. It's good to know that the fans are still spinning, as that indicates there is still some power going through the system. Here are a few steps you can try to troubleshoot the problem:
1. Check Power Supply: Make sure the power supply unit (PSU) is properly connected to the motherboard and that the power switch on the PSU is turned on. You can also try a different power outlet or power cable to rule out any issues with the power source.
2. Inspect Components: Check for any visible damage to the components inside the PC, such as burnt marks or swollen capacitors. If any components look damaged, they may need to be replaced.
3. Reset CMOS: Try resetting the CMOS (Complementary Metal-Oxide-Semiconductor) by removing the CMOS battery from the motherboard for a few minutes and then reinserting it. This can sometimes resolve startup issues.
4. Check RAM and GPU: Reseat the RAM sticks and the graphics card to ensure they are properly seated in their slots. Sometimes, reseating these components can fix booting problems.
5. Test with Minimal Hardware: Disconnect all unnecessary peripherals and try booting the PC with only essential components (CPU, RAM, GPU) connected. This can help identify if any additional hardware is causing the issue.
6. Test with Different Components: If possible, try testing the PC with different RAM sticks, GPU, or PSU to see if any of these components are faulty.
If after trying these steps the PC still doesn't boot up, it's possible that there may be a more serious hardware issue. In that case, you may need to consult a professional technician for further diagnosis and repair. Let me know if you need more assistance!
