75% of the time i put a disc in the dvd drive the computer always restarts itself wither it be a cd or a dvd or a computer game i hear the disc getting read and the computer restarts itself any ideas of what to do........plus when i try to play a game it says please insert correct cd-rom but it is the right one and when i enter it again the computer switches off thus it does not read the disc if u understand me??
