Can't Access Internet Limited Connection Only?

I'm in need of some serious help here. Working with a Dell Inspiron 1750 laptop that's running windows 7. The machine can not get full access to the Internet. It seems as if there is a software conflict, but I can't find what it is. It did display the BSOD a couple of times, but the screen was gone before I could see what the codes were. The system restore only has 2 days of restore points, neither did anything to help.Running the diagnostics produced the following codes. 0f00:0232, 968634624, 0x490, 0x8007042c, 2000-0151.All repair options suggest patches that require an Internet connection. Well...if the computer had an Internet connection I wouldn't be in such a state. Reminds me of the car repair manual that says to start the engine to preform a test when the problem is the engine won't start.Anyway, I'm at a loss. This isn't even my machine, it belongs to the sister in-law, which means I have no idea of what she may have done, if anything, to cause the problem.There's a lot of Apple software for the ipod, or itouch, whatever it is she uses.I can't access the recent update history, so I'm not sure if updates are a factor.It sure seems like a software issue, but what do I know? If I knew what I was doing...I surely wouldn't be here seeking help.One other thing, when the machine is first booting, a window of some sort appears just after the desktop appears. It only flashes for a split second before disappearing. Not long enough to tell what it is.Well that's all I have, I sure hope that someone has an idea. The computer isn't even 2 years old, so it'd a shame to have to throw it away. As far as programs goes, it has very little, and the 500GB HD isn't even 25% filled.
