So what exactly is the problem? You started off saying there's a password you don't know, then it morphs into being about video drivers, ending up with whether or not the video card is bad.
so i traded my xbox 360 with lots of extras for a dell vosto 1000. i get it home to find that there is a password keeping me from getting into the bios. they gave me the password to boot the os. real i would like to get rid of it all together. also i have not been able to install the video driver. they even gave me the disk it came with that includes all the drivers ( probably out of date) for it.when i try to install it it says there isn't any hardware that matches it or somthing along those lines. is this a sign that the video card is bad? someone please give me some insight and atleast tell me i didnt get ripped off.
