over killed PC. overloaded PC

My PC originally came with 8 GB RAM. I upgraded to 32 GB and with yahoo finance live open, 50+ browser youtube tabes open, 1 game running for 18 hours per day(in background).... the RAM is over loaded and when I do video editing for Youtube with "Movie Maker Video Editor Pro" the RAM overloads reaching limits and blue screen comes up.... I read news that 128 GB mini PC with GPU is round the corner and waiting to buy 1 when HP launches it. do you guys have any tips on how to increase productivity with such overload on PC? my PC is Intel 12th gen i5 processor from 2023 and its already old.

Honestly man my pc struggles to load hentai nowadays.
