My DC is broken? It resets itself!

I have a problem: my DC worked fine for a few months now with CD-R's, now suddenly it starts to reboot itself!
Is my lens broken or what? I use quite good CD-R's; Traxdata, MMore, Imation.
Please do not tell me the DC is broken, because it's so hard to get it repaired here!
Thanx alot!
