[patch22]

hi i have problem i have got magic 3 chip on my ps2 and
i just copy ps2 dvd rom game it copied perfectly and the ps2 booted the game perfectly after 3 minutes the ps2 turned itself off we tried it again but it kept doing the same thing we called up the company who fitted the chip and they said it must be something wrong with the laser the thing is the ps2 is brand new its only 2 months old do u think its something wrong with installation of the chip and not the laser

i have pioneer 104 dvd-r/rw
nero dvd burner
tdk dvd-r blank cd


thanks
