After updating system, my PC getting slower

Hello everyone. I was trying to install discord to my computer. While I was installing, computer did all system updates also. After everything is done, my computer getting very slow. For now, I can’t open a new tab on my browser. What should I do?
Additionally, I am newbie for manjaro.
