My newly built PC keeps lagging somewhat, during some tasks. The first problem was when I was transfering 200 GB at 100 mb/s from an external harddrive. My mouse stuttered beyond use. Now, microsoft word lags when I type. In addition, sometimes my Windows toolbar on the bottom "refreshes" when I switch program, so that I am unable to push the windows button. I am worried it is mobo issue, although I'm out of ideas. I've updated all the drivers except wifi (since when I do, my wifi shuts off forever for some reason). Please help. Thanks.
