Hey Guys

My inspiron 1750 took an epic crap this week. in the same day my lcd screen stopped working (LCD cable problem) and my wifi card stopped working.

Now after hours of research i seem to have figured out the wifi problem.  I believe when i was hooking up the external monitor (so that i could use my laptop while waiting for a new lcd cable) that i acidentally disabled the wireless card in my bios settings.  The problem im having now is the fact that, when you boot the computer with an external monitor, it doesnt show anything on your screen until windows starts to load.  So i was wondering if one of you kin gentleman (or ladies) would be ever so kind to guide me through the exact procedure to enable my wifi card again. by this is literally mean a step by step on each exact key you press to get to where.

Thank you in advance for your time
