I recently upgraded the RAM in my PC that I got as a Christmas gift, but now it won't boot. The computer turns on, but there's nothing displayed on the screen, and I noticed a yellow light on my motherboard. I tried swapping out the new RAM sticks in all available slots, but it didn't help. I even put my old RAM back in, but it still won't boot either. Am I doing something wrong here, or could my motherboard be damaged?

Make sure your RAM sticks are compatible with your motherboard. It’s crucial to check the specifications on both ends. If you bought DDR4 RAM but the board only supports DDR3, it won’t work. And definitely avoid static discharge; wearing an anti-static wrist strap is a good practice to prevent damage.
First thing, try resetting your CMOS. After that, test with just your old RAM to see if that works and ensure it’s fitted correctly in the slots.
Make sure you seat the RAM sticks properly — they often require a decent amount of force to click into place, and you should hear a snap. The yellow light generally indicates a DRAM error. Try using just one stick of RAM at a time in different slots while ensuring all cables are secured since you might have knocked something loose during the swap.
Absolutely! You should definitely hear a click when it's seated correctly. The notches on the RAM should align with the clips, making sure everything is snug in there!
If those tips don’t help, unplug everything from the PC—your monitor, keyboard, mouse, and all that. Then hold down the power button for about 30 seconds to reset it. This helps discharge any static. Afterwards, just use one stick of RAM and see if it boots up.

Right! Compatibility is key. Gotta double-check that before buying new RAM. And yes, always take precautions against static, especially when working inside your PC!
