My ps3 does crazy stuff when I try to put in discs, whats the problem?
The way that you would go about fixing a problem with your PS3, would all depend on what it is doing when you put discs into it. You may just need to clean it. If this does not help, you can have a professional look at it.
Definitely clean it, maybe unplug it and leave it alone for awhile if that doesn't work
