Help Needed!!! One Of Those Days!!

[Filbert]

I'm having one of those days when everything decides to go wrong!
My Samsung 4 tablet decided to switch itself off and when I tried to turn it on, the startup screen lasts a millisecond then turns off. Have no idea whats happened. Any ideas? I've looked on forums and tried their advice but still no joy.
So I decided to have a few games on my ps3..that freezes on the startup screen (the wavy line) and can't do anything.

Please help before I go mad.....
TIA
