The missing/corrupt file is: <Windows root>\system32\hal.dll
The black screen on my mom's computer says that we need to reinstall a copy of this file. She can't find the disc(s) that came with her computer.
I'm not a tech guy by trade (mechanic), so I don't know if I can get and install a copy of this file, or if I need to shop this one out.
What can, or should, I do?
