my 3576 inspirion would  usually shut off without any warning. This happens very often  , usually right after I play games like FIFA or when  I've used it for quite a while (like 5 hours). One more problem is that occasionally the laptop would suddenly stunned and I can't use the mouse or the laptop but everything else other than that operate normally (ex: the  youtube video on the browser just keep on running just can't use the mouse or the keyboard ) and when I plug my laptop off the laptop shutdown (even if the battery is full) . Does anyone have any suggestion what I should do ?

P/s : I'm pretty sure it's not the battery problem as I've tried to unattached the battery and plug in the charge directly  to the laptop and still have this problem . I've also updated the BIOS and any other driver . I hope this help
