Dreamcast is having problems reading discs.
I bought a used Dreamcast the other day at a local game store and it has been acting weird since. After extended playing (maybe 30 minutes to an hour), the laser will start to go berserk making a lot of noise and the games will cease to play. If i try to turn the console off and load another game (or the same one for that matter) it will do the same thing. After leaving the Dreamcast alone for a little while it will read games again. This doesn't happen all the time, however, because sometimes I am able to play for hours with no problems. I'm guessing that this is either an overheating issue or something to do with the laser itself. I've done an obscene amount of searching on Google and have failed to find anyone who has had this exact problem. Any help would be much apreciated and thanks in advance.
