hi. my toshiba satellite c850 randomly(i think) shuts down and when it rebooted, i stumbled upon this automatic repair thing. and the only way to get my laptop to work again is to use system restore. which i did for a few times. it sure made my laptop usable again but later it shuts down again. then i would do the same thing.
First try System File Checker
Winkey plus 'X'
Choose Command Prompt (Admin)
Type
sfc /scannow then
Enter
If that fails to find anything, time to look at your Hardware, start with RAM. If you have more than one stick, try running on one at a time and in different slots.
Also check your HDD for errors.
