Sometime not responding while using hackintosh bigsur and monterey

I'm using opencore guide with i7 3770, asus h61M and gt730 ddr3. Everything working properly except sometime suddenly not responding and can't do anything just showing loading. It's happening day to day use with chrome, finder, video playing,... . After reboot, It work normally. During these day, it happening more and more. What issue can be ? please suggest the solution.
