i tryed them both, also tryed OBS (open brodcast service) to find the cam but to no good.
on the first link it said no camera found, on the second in the list were you choose camera it just is blank, like no cam at all. the same thing happend at OBS, the shit just got blank and no option on selecting my internal cam
i bought it Without OS, and i installed a Windows 8.1 on it. it think it HAS worked once before. but no more.
also a of topic question. i had to break the "warrenty sticker" on it becuase i needed to take out the Hard drive a cupple of times, is there a way or site to buy that warrenty sticker again? if that's so, i'll also replace all the skrews :I i mean if the Cam don't work
ok then return it to where you bought it, explain to them that the webcam doesn't work. they will either test it, and make it work or replace it with a working one. oh before you leave the place where you bought it test it or make the sales rep/technician show you how to use it. (just to make sure it's not defective again.)
