High CPU usage windows 7 Tags: NICs CPUs Components Last response: November 15, 2009 3:10 AM in Components Share yliop143 November 14, 2009 10:47:10 AM hey i m on w7(64bit) and i have a quad core processor 2.6ghz atm but the important part is that the cpu usage is around 80% on one core and around 30% on another. the resource manager says its 15% system procces and 10% system interrupts when i turn off my onboarad realtek NIC (lan) it drops back to 0-1% usage on all core. the problem is im using that to connect to my modem and to internet so its not an option to disable it. what i did?: - installed new NIC drivers/ uninstalled. let to use windows default one . (no luck) any info/tip/opinion is appreciated , feel free to drop by and comment. thanks.
