Laptop freezes due to high RAM usage

Hello,

Unreal was working fine but then we did UI to the project. After that, I just can’t run my project from Visual Studio. My RAM(8GB) usage goes upto 95% and laptop just freezes forcing me to restart. Also, opening the project directly through Unreal results in the same issue. However this does not happen on my teammate’s laptop. After a bit of google, I tried updating my drivers but no use. Could anybody please help me? This is for a school project.

System config:
i7 quad core @2.2GHz
8 GB RAM
1TB HDD
NVIDIA 650GTM 2GB
No SSD

Can somebody please help ?
