heat problem or not
install m2, but everytime for some reason the systems exits the game 10-15 min after i start playing, it sometimes just ejects the cd tray by itself or it shuts down into stand by mode (not fast flashing which is heat problem, just solid red)!! Sometimes it does it as it's loading the game, even once it shutdown started flashing eject over and over, it's all trippin out. But about 90% just shuts down to reset solid red status, was thinking it could be a reset wire or could this be a heat probelm? Fan is working, all 9 screws are on the bottom of the pcb and heatsinks is on tight.!
No heating problem the symptom of overheat they is it blinks the red led of reset.
Maybe have a cold solder check all solder points and resolder again all.
If the laser is bad maybe the symptoms is from this ( i dont thing).
Is the laser OK ?
Is there some solder bridge near RESET which is near the Tray solder pads?
Are you sure the ribbon cables around the disk drive are properly seated and not grounding anywhere through a break?
Is the M2 not grounding on the metal cage?
That sort of thing?
