From then, the mouse n keyboard have so much lag that they are almost unusable. I changed to another brand new wireless mouse but reuse the keyboard. All my new n old peripherals are logitech which i think using 2.4ghz frequency. Mouse seems to get better for a while but still quite laggy. So i removed the USB wireless adapters of these peripherals and plug them to the front USB ports instead. It got much better but occasionally still got lag.

I had a similar issue as yours. For me, the issue was the RAM. I had 2 pieces of Gloway 16 GB 2400Mhz DDR4 (total 32GB running in Dual Channel mode), which is not stated as compatible with my motherboard. To resolve it:
1. Either take out 1 piece of 16GB RAM
2. Use other RAM
