Solve : Network card not working :(?

1.	Solve : Network card not working :(?
Answer» My laptop's MONITOR has been cracked for the past YEAR, this wasnt a problem, since I could use another monitor, but last month it went out completely and the monitor settings reset leaving me without a WIRELESS connection :/ (this was before i found out about the fn+f3-f5 deal) So I took the network card out and tried installing it on my other laptop, didnt work, the thing wouldnt even start, so I put it back into the original laptop. Installed it, has the right DRIVERS and everything, but its TELLING me that (error 10?) it wont run because its not signed by microsoft, and therefore I cant use it. Ive searched what feels like everywhere on the internet for a solution, anything I can do or any help would be appreciated, anything to get me off of dialup. I can provide more information if needed. Thanks in advance.
