Hello everyone, normally I am fairly proficient with computers and capable of solving computer problems on my own after some google searches and experimenting, but this one is throwing me for a loop.


I have a Windows 7 machine that has one of the cpu cores that keeps getting maxed by svchost.exe (25% overall usage)


Now when I open the resource monitor and find the offending svchost in the overview tab, it is named "svchost.exe (LocalServiceNetworkRestricted)"  Once I tick that one, and then head over to the CPU tab, I find that the offending services are always one of the following 3 Dhcp/Audiosrv/eventlog (sometimes it bounces between the 3, but usually Dhcp is the largest/most common culprit, Audiosrv is second, and eventlog is least)


The system is otherwise running well, I did a scan that found nothing with Nod32 antivirus software that was expired (at which point I uninstlaled it), I have since gotten the free version of Avira, which also found nothing.  MalwareBytes found nothing, and windows defender found nothing.  This leads me to believe its a windows problem, and not a virus/malware issue.


Thanks for the help

I decided to update the motherboard's sound drivers to the latest ones on their website and that fixed the problem!
