End up i just add in a spare ram, no issue. Next time will bring to my it guy to install it after i purchase ssd.
My it guy told me many user nagging at him because the ssd + ram too little. Use zoom for vc , open powerpoint, whatsapp, and email also can out of memory/hang. Quite surprise 8gb ram not sufficient for the office usage apps.
Anyway, i'm not working in some high security place like gov sector/big mnc that don't allow copy data over usb, etc.
Case closed. Thank you.
