when going on task manager the cpu usage jumps from lower than 10% to 100% and an application or background process uses high power and most of the cpu. i want to know why my pc is only 7 months old and i dont know why its going this. im not having any visible impact on gaming it just worries me that it will break. the spikes sometimes are linear and sometimes are not but it goes high to low to high again and its not a virus or crypto miner as i have run scans on multiple anti virus software i dont know if it is the motherboard or cpu or power supply or anything
