HANG! HANG! HANG! :(

[KOC2000]

Guys pls, someone help me...
I've a JAP PS2 10000.. /SwapTrick mod-chip...

I can't play most of the games I've got later.
GT3 hangs after the Kalisto Logo.
GTA hangs after the PARADOX(Loser) LOGO.
Onimusha hangs after I choose NEW GAME.
Devil May Cry hangs after I enter the door in the second mission (the one just at the left of that state holding the SWORD)...

and so on...
I'm sure that GT3 works well.. I tried on my friend's 30001 with the MEMCARD Manager cd/SBox USB chip...
-----------------------
MY Console is very NEW.. I tried them also on a 15000 JAP PS2 and the same results...

I tried adjusting the laser and! also no hope

The man I god the CDs from made them with CloneCD...

THANX
