I bought an Mr-76 about a two years ago.. abouth 4 months after buying it, it began to lock up on a regular basis until i couldn't even turn the thing on. I had it repaired under warranty thank God, but now a year or so after having it back it soft reboots itself! all the time! if i try to access the disk drive it will immediately, it will also do it randomly while playing, and now when i turn it on, it reboots itself before it even has a chance to initialize, and it continues to do so indefiniately.!! help!! has anybody had similar problems?? how much did it cost to repair?
