I accidentally spilled some water on my laptop (dell inspiron n5030) and when I tried to turn it on later, it wouldn't work and show error message "hard drive disk not detected". I reseated the hard drive (took it out and put it back in) and everything seems to work fine now, just that there are no wireless drivers anymore. In device manager under "Network adapters" it only shows ethernet controller. I downloaded "Dell Wireless WLAN 1501 Half Mini-Card (4313bgn) Driver" from the dell website and it is supposed to be compatible with my laptop and system(Windows 7 32-bit), but when I try to install it, a setup error message comes up saying "no compatible hardware found. The software you are attempting to install is not supported on this system". I also checked, wireless is enabled in the BIOS and the automatic wireless button on the keyboard (F2) is on. Does anyone know what the problem might be? Is it possible that something got damaged inside of the computer when the water got spilled and that's why I can't install it? I'm not very good with computers so any help would be very much appreciated.
