Hello,
my laptop is randomly shutting down. Its not overheating because i have a special cooling pad and its kept in a cool room . The drivers are from manufacturer website and are compatible and up to date . I cant do a system restore because i dont have any restore points created and a clean reinstall is out of the question because i have over 200 gb of personal data. Samsung R522 (Core Duo @ 2.0ghz ,2gb ram ,Ati Radeon 4330 HD , 250gb seagate hdd OS: Windows 7 Ultimate SP1 x86 )
the boot up time after shutdown is normal , usually its pretty fast . I am 100 % sure it not overheating because the cooling pad has six 80mm fans and the r522 has a reputation of having a very good cooling system . I also tested it for overheating by running Crysis 2 at full settings and it overheated to the point where the keypad got almost unusable because of the heat and it just restarted after 3 hrs of usage . It did not shutdown .
