Up until about 4 days ago, my system would spin up and read my backups. Now, it plays burned dvds, pressed dvds, games, music discs fine. However, when I try backed up games, they won't spin up propperly. Disc starts to spin, but slows down within seconds of starting, and it tries to spin again, to slow down again. It does this 3 or 4 times, then Free McBoot restarts itself, skipping the disc spin up process.
Any ideas? I fear it may be the laser going out, but I can't do a cleaning on it (only rubbing alcohol I have is 50%, not pure enough for me to risk it). Suggestions?
