I tried to upgrade a pc from 2009. It didn't work but I thought it would, so I cut three wires from behind the DVD drive going to the old wireless card because they were in my way. I thought I would be able to pull them out of the case but I can't. And the DVD drive's Bay is riveted in. So now three cut wires are just hanging there. Is this a fire hazard or is it ok to put everything back and pretend it never happened?
