Hi guys, I have had my toshiba satelite A500 laptop for.. since it came out basically, I have never opened the laptop previously, since November last year, I have been having difficulties with my laptop, And about 90% of the time the laptop will shut of anytime between 2 minutes to 20 minutes of playing a game. It doesnt seem to shut off if im browsing internet, chatting on MSN, or even watching a movie. It only seems to shut of when im playing games, Which i do on my night shifts. I have a cooling fan underneith my laptop and it doesnt do much of a difference. I have monitored the temperature on Toshiba Pc Health Monitor. And it says CPU temperature 42-50% normally. When playing games the highest ive seen it is 81% which is in degrees C. I have been told to use canned air, But im not 100% were to put it, And ive been told to open the laptop up and do it myself - which im not confident at doing at all without a instruction manual, Which i dont have. Sorry for the massive page, But i thought the more details the better. Anyone got any suggestions? Ive browsed about but have not found much, Only "use canned air" But i still dont know were to put it, And cant find out about opening this. Sorry guys for the trouble, And im new to the forum Hello My name is Dan.
