I would appreciate help in solving this problem or pointing me in the right direction. Searching the internet for solutions has been frustrating and nonproductive.
I have been having intermittent events of system interrupts taking up more than 50% of my CPU and dramatically slowing down response time. Through trial and error I have found a correlation. It seems to only happen when transferring files between the computer and other computers on my home network. It happens both via ethernet (wired) and wi-fi. The drivers for both network adapters are relatively current (2013); and when I try to update drivers via device manager I get a response that the existing drivers are the most current. The problem does not happen when viewing a video file from another computer on the network. It does not happen when copying files between sub-directories on the hard drive.
Computer is a Lenovo ThinkPad X120e which originally had Windows 7 but has since been updated with Windows 8.1. It was never a fast cpu to begin with and I never checked CPU usage until recently; thus I can't tell if this always happened or started more recently. The computer is current with all Windows Updates and Lenovo updates; and I've updated the BIOS to the current version (2013).
Thanks
