Help Unresponsive screen

[Slice28]

I have yet another problem now occurring with my Evo.. randomly my screen will become unresponsive .. it will pretty much be the lock screen without the time and date bar.. just my background and notification bar at top and nothing works at all.. the only way to fix it is by taking the battery out and putting it back in.. i have no idea what is causing it, but it seems to happen randomly.. today it happened about four times throughout the day.. thankfully im getting a new one in a week or two because of the usb port randomly breaking
