so my acer was working just fine until I got it backfrom a roommate and when I tried to turn it on is had said disk read error press ctrl alt del and I did it many times but to no avail, then I pressed F2 for setup boot or what not and now I says nothing but a black blank screen and will not respond. I have no idea what to do and this campus has no wireless so I cannot download a driver update or whatever it needs to be fixed. so if any help can be thrown out it would be greatly appreciated
