I have Acer Laptop with the windows 8 OS preinstalled. I don't know what happened, exactly after one month of usage the machine restarting automatically. This is happening many times in a day, I don't know how to stop it. But I tried to fix this with the Auto Repair option of windows 8 but now this couldn't even fix it. Am still facing the restart problem even after running the Auto Repair. Suggest me what to do?
