Friends, ML2 installed on my machine with the following configuration.

I7 3.0 Processor

Motherboard Gigabyte GA-58XA-UD3R.

Ram Memory 12 GB DDR3 2000. triple channel.

Sansung HD 160 GB Sata.

Asus DVD optical.

Well, I made several facilities to see if the crash was recognized that the reader gives error (-7012).

I installed Roxio Tost 10 and some DVD Player and swapped the optical, but also gives the plumb error. Googled some tips I saw but did nothing, waiting for some response from you.

I thank you.
