I am having issues fixing my sister's laptop. It was purchased a couple months ago, and recently after installing updates, it would not boot into Windows. It gave an error about her ethernet card. After doing some research I concluded that the BIOS was going through its boot priorities and returned that error on its final option, meaning it could not boot off of the hard drive.
I tried a bunch of stuff to fix it, nothing worked. Eventually I just did a clean install of Windows. It was fine for about a week, but then it started happening again. No updates were installed this time around. A repair CD fixes it for a couple days, then it happens again. Here's the last message the repair disc gave. I'm not sure if it's the same as the previous times, but I imagine it is.

Frankly I am out of ideas. I can't fathom why it would continue happening after a clean install. It is currently working, but it will just fail to boot again in a day or two. I'd rather not make her run the repair CD weekly, so any ideas would be appreciated. Thanks.
