Ginge

Hi there, I turned on my computer this morning after shutting down last night when it gave me a warning box, I thought it was just a program I was using freezing, as it had "sam" in it somewhere (I had been using SAM broadcaster), anyway, in normal startup I'm getting a black screen with cursor, safe mode works fine (I'm in safe mode with networking at the moment, running a full virus scan) but in normal, nothing will work, ctrl alt del, sticky keys, just nothing. I tried system restore but it says there are no restore points. I don't have the windows 7 disc. The laptop is only a couple of months old. Any advice?
