Hey everyone, I tried to fix my old laptop so it could stream videos online, but when I swapped the RAM stick, the computer wouldn't start up at all. There was no BIOS beep sound, and nothing appeared on the screen until a couple of seconds later when just the power light turned off completely. I thought I checked everything right before swapping, maybe I forgot to match one exact thing with the other old sticks? The new memory is from HMA: SK hynix RAM, 2666MHz non-ECC DDR4, 4GB capacity running at 1.2V voltage and it's all brand new in its packaging. On the other side I put ADATA RAM, which also says to be 2666MHz non-ECC DDR4, but this one is a bit different with 8GB instead of 4GB and it has a specific part number: AD4S26668G19-SGN. My laptop model is an ideapad 330-14igm thanks for listening.

You need to update your laptop's BIOS. Then, try putting the new RAM in and see if it works. What CPU do you have? It probably only runs at 2400MHz. Maybe the new RAM is just broken or doesn't fit right. You could swap out for something else like this link: https://pcpartpicker.com/product/k7...dr...400c16-s01

thanks for getting back to me! i changed my BIOS chip before swapping, and my CPU is an Intel Celeron N4000. i tried using a RAM stick with the exact same speed as the old one (2666MHz), but it still won't work.

The CPU is running at 2400MHz, which means it's under normal settings or just barely overclocked. It works fine here, but maybe not in this specific situation. Check out that link for more details on the N4000 processor with its 2.6GHz speed and cache.

Hey, sometimes the RAM sticks don't fit snugly in the slots. Try putting only one stick in first to see if that helps. Swap out some sticks and try different spots on your laptop. You can also wipe them down like this: https://www.youtube.com/shorts/3Np1uEhb8F4 just remember not to hurt the chips, only clean up the parts touching the slots. Over time those contacts get rusty. If that doesn't work, try putting the sticks on another computer and run Memtest86 to check if they're okay. Most Linux downloads come with this program already included, so you can make a bootable USB stick and test them right there. This will tell you which one is broken.
