I have an otherwise functioning install of Windows 7 64bit edition. Sometimes, the process NT Kernel & system jumps to 20-30% CPU utilization from its usual 0. I can sometimes go a week without it happening. Sometimes, it's an hour. It goes away if I reboot. It also goes away permanently if I disable the 82579LM network card. So, that's the problem.


I've tried the Dell drivers, the last 2 or 3 versions of Intel drivers, and it still occurs. I've also tried virus and malware scans. Anybody have an idea how to fix it? It's not a huge deal, but I'd still like to fix it.

Get all of the windows updates if there are any. You may need to reboot a few times, keep checking for updates until the computer reports there are no more updates.

If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
