Windows 7: Computer shuts down by itself

Windows Ultimate 64 bit
Computer shuts down by itself

today i've cleaned my laptop's fan and reinstalled my windows
since then my computer starts shutting down by itself without any kind of error apearing on the screen, i had a look in event viewer and founds this:
'The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.'
so i checked the details and it showed this:
