My asus a620 keeps pissing me off. Hard resets, EVERY TIE<



Seriously, what is up? Everytime, my asus just hard resets. I leave it turned off, an hour later, the battery seemed to be drained, and it hard reset. Isn't there a backup battery that saves everyhing and shuts it off? Seriously, WEEKLY hard resets. Getting so pissed, all my files getting deleted.
Please tell me a solution to this. Thanks.
