Why does my mouse pad keep failing?

Sometimes the mouse pad on my laptop freezes up, and I can only fix it by doing "control alt delete" and shutting down my computer. I can still use the keyboard, and I can manually swap between windows (windows button + tab), but it is very difficult to do anything without the mouse. Lately, I have noticed this happening more and more frequently, and it is rather annoying to have to shut down my computer just to get my mouse working again. If it helps, my laptop is a HP Pavilion dm4-2033cl, which runs Windows 7. I also have been playing more Minecraft lately, which I think might have something to do with it. All help is appreciated!

When you are playing Minecraft have you noticed if your computer is getting hotter? If so this could be why you are freezing. I would suggest giving the HP Support document below a read and see if it helps you.

I hope this helps resolve your issue. Have a great day!
