I use windows xp home sp3. When I insert a cd into the drive it crashes and the screen says that it has protected the computer and I have to reboot. I look at the event viewer and it shows nothing. The device manager shows okay. My pc shows no virus and everything else works okay. Before this my router, D-Link dsl-534t, was fried. I don't know if this has anything to do with this or not. I am using an old backup router that at the moment works okay. I've not had any problems with the cd's before. I have no idea where to start to fix this. Any advice and instruction is appreciated.
