I did an install for a duo chip on a v7 about a week ago. everything went fine for about 2 weeks, then basically, it stopped working. all I get is black screen on boot and the blue eject light doesn't even come on. did I blow a fuse? all the connections are solid. the only thing I'm wondering about is that I used slightly thicker strand wire for 3 of the BIOS pts. because I ran out of wire. can someone tell me what may be happening?
