Laptop beeping on boot

Edit: https://youtu.be/zIvhNyGYd5w?si=gRagCBpMn8xTMNpx

I opened the backplate and noticed one of the ram clip is loose. Then i booted up with memtest86 and held the ram with my finger and eventually I moved my hand and it crashed. Then i booted up with backplate open and put a fan directly at the ram, so it doesn't get heated.

Google search told me that this crash happens after the ram got heated up.

Is there a permanent fix for cooling the ram. So I don't have to keep the backplate open and keep fan over there all the time. Does laptop fan stand help? I already spent so much money on this things and don't want spend another for laptop fan stand.

Edit: 1-3-3-1 beep sounds

*beep* gap *beep beep beep* gap *beep beep beep* gap *beep* happing while booting the laptop. Specs Lenovo b490 tamilnadu government school laptop Amd A4 4300m.

I used to have an Intel a1018 model. That laptop keeps restarting on boot so I gave to repair shop and he changed the motherboard and processor and ram. Now the system boots normally sometimes but if I restart or turn it off and on again this beep sounds comes and won't boot into windows
