[Need Fix] iPod crashes frequently, vertical lines appear before crash, Time and Date do not work, WiFi disconnects every few minutes

As said in title, iPod crashes frequently, vertical lines appear before crash, Time and Date do not work, WiFi disconnects every few minutes.

By time and date not working I mean, for example, the time will stay at 7:49 AM for hours, then possibly go down a few minutes, date will not change day, and timezone doesn't work either.
