I was playing minecraft till a few days ago just fine, and today when i joined Hive, i got unplayable performance, i know my pc is a old 2009 Dell, but it was going fine. While it was lagging, I opened task manager to see what app was causing the lag, and found out zhat system interrupts was taking from 25 to 50% of the cpu, only when i join any world, and bcs of that minecraft only uses 15% of the cpu. While playing other games, there wasn't lag. And system interrupts wasn't causing any issues.

Pc specs:

CPU:Intel core 2 duo e4500

GPU: Nvidia gt220

RAM: ddr2 4GB

I tried many things, but it didn't work.
