Does anyone have any idea how to figure out which driver is causing constant CPU usage by SYSTEM process? It used to constantly hover at around 15% but it fell down to 5% after updating Broadcom WiFi drivers. But i’d like to find out if it’s still WiFi driver or something else.
I followed some guide by Mark Rusinovitch how to find out exactly what i’m looking for but his guide only involved 32bit system. And same method doesn’t seem to work on 64bit Win7.
The thing is, when i boot system in safe mode, CPU usage actually stays at 0%. But in normal mode, constant 5% usage which is annoying and unnecessary and just eats battery since it’s a laptop.
