‘System’ process taking a lot of CPU

leave a comment »

My desktop PC had a strange issue recently when it suddenly slowed down a lot. I saw that “System” process started by ‘System’ was taking a lot of CPU cycles. I couldnt understand the reason (because ideally System Idle Process shows the max CPU which basically means that most of the system is idle)

Some googling around revealed that some buggy USB drivers cause that. I removed all the USB devices out from the system and presto! it started working fine!

The culprit was a USB camera ┬áconnector that we had plugged in a few days back and let it be there. Probably it’s USB driver was buggy.
