I have a cheap and cheerful laptop a medion akoya only a few months old, it is only ever used as a backup for family photos. I updated to windows 8.1 in the last day or two and now my mouse pointer keeps freezing on startup and will not unfreeze after any period of time. It only does this on my profile not the guest account. I have ran the hardware and devices troubleshoot and checked if the driver needs updating, but there isn't a problem with either. Can someone please help?
