Xbox 360 randomly shutdown during 3 hour game play and wont switch back on ?

Was playing Zombies on COD and up to level 26! when my xbox just suddenly powered off! and refuses to switch back on!...... Am guessing its overheated?

I have my 360 vertically standing up does that make any difference? + is it now dead?

Working now but my power brick went red so am guessing that overheated

It was kinder jammed in a hot stuffy corner, the same as my xbox. Plan to move them and mod the brick and console with some fans
