I'd let them fix it.
-> Notice what details you told about this PC.
I've recently got a new computer and I've pushed the other one to the other side of the desk, and after trying to boot a few times without a keyboard, and then connecting the keyboard (why would that change anything?) and using it a bit without a keyboard, it suddenly doesn't want to load up! It starts loading and all, even when the keyboard is connected, and it 'freezes' when it gets to a screen that talks about how the volume is clean. Arg. And I don't know how to start it up, or use the setup, or start it in safe mode. (I dont want to lose the data).
