I performed a thorough cleanup of my PC using a vacuum and anti-static precautions. I used a tissue paper to gently clean the fans. Once the system started up, it failed to boot properly—yellow light on the motherboard indicated DRAM activity, but no green boot signal appeared. I restarted the PC multiple times without success. I inspected for loose wires but found everything secure. Should I consider re-seating the memory?
Reset your memory and look for any debris on the pins. If this doesn’t help, test by connecting only one. If you’re using multiple sticks, repeat the process with each one.
