I plugged my keyboard in and all was well. upon installing the software that came with it, the keyboard stopped responding. after deleting the software, i tried plugging the keyboard back in and it wouldn't even make the sound effect of a device being plugged in. the keyboard worked fine on my other computer when i tested that. my os is vista, any help would be greatly appreciated. i checked the device manager and removed all keyboards that were listed. the keyboard i was using before works fine, just not the new one.

is it a usb keyboard? If so it must be enabled in BIOS. Also if enabled OK, then when at desktop next,, unplug and re-plug into another usb socket and it should be detected and a driver will install, thaat may fix it?
