Sometimes it locks up for a minute or two, can't open anything, HD light comes on. Checked Task Manager and my browser shows high CPU usage (see attached screenshot). I have a desktop running Windows 7.
I bought it as a refurb from a computer fixit shop in 2012. They probably installed the OS with a blanket license, so likely the case doesn't go with the updated software. I have an inquiry in at GeeksToGo web site. Awaiting advice there.
