About a week ago I decided to change the thermal paste in my sister's laptop. It ran fine while she played emulators and watched youtube. However once she went back to her house it started acting up and it BSODed. She said it could then boot her into safe mode. After her rebooting several time ( I have no idea why, she lives a hour from me and I had no way to get to her at that time). Now it displays nothing at all, the fan just turns on and then it shuts off 10 seconds later. The warranty for the laptop is expired and she doesn't really have money to buy a new one so fixing this one would be nice. Thanks in advance.
