The system is not starting and will not boot further.
Hey, your PC came back from a long drive and you changed the cooler. After installing the new one, the motherboard lights are blinking but nothing happens when you press power. The CMOS reset didn’t help. Here are some ideas: check connections, try a different power supply, ensure the GPU is properly seated, and verify the fan control settings. If issues persist, consider testing with another power source.
You probably hit the RAM, which might prevent the system from starting. Try reinserting it. Also, reattach all the power connections—there could be slight movement during setup.
Certainly! Here is the guide rephrased:
Follow this instruction carefully before proceeding.
I just replaced the CPU, reinserted the RAM, verified all power connections, but nothing changed. I’m not seeing any postcode lights on the motherboard and can’t locate an internal speaker to detect error sounds. The LEDs on the motherboard when I power on the PSU suggest it’s not a power supply issue. Any suggestions? Could the new fan be the cause? I’m really uncertain about what to do next.
The test confirmed the power supply activated correctly, and measurements showed voltages slightly higher than anticipated using a multimeter.
The PSU appears fine. It might be a dead motherboard or a failing CPU, though less likely. Next, I’d remove the motherboard and verify there’s no contact with the back that could cause a short. Inspect the standoffs too. Then place it on a non-conductive surface (like the box if available), install just one RAM stick, leave the GPU off, and remove any SSDs. Try turning it on—see if a power LED lights up or if the fans spin.
