So I have an HP Invent laptop, with Windows Home Premium 64-bit. At least I think so, It was a gift from my parents, and I don't know a ton about computers, or use them for much besides a lot of software and forums. But anyway, sometimes, when I go to the desktop, my cursor will freeze in the top left corner. It's very irritating, but it only happens when I'm on the desktop, It will then only work in the task manager, and nothing else. It's a matter of restarting all my programs, and losing everything that's open. It's just quite annoying. So if anybody has some ideas why this is happening, your ideas would be greatly appreciated.
