My final cry for help (please read/help)

Your machine is sensitive to what type of disc you use, the older machines will not play every type/make of disc that is on the market. I have found the old machines seem to prefer the gold type disc, I put a mod chip in a machine the same as yours yesterday and it would only read games copied with Nero(cdrwin & Clone CD failed), I live in Australia so I am not sure what type of discs you can get.
One of the problems with your machine is the power source is located directly under the laser and the heat from this will effect your machine.
1) try different discs
2)try your copies on some one elses machine
3)If you buy a new machine only the Japanese PS2 can be mod chiped and the PS1 needs games to be patched to country origin
