First of all, Hello to everyone in this forum. Now my problem: Seems like a PRAM problem, colored stripes changing and OS X not loading. So i tried the PRAM reset, chimes 2 times, seems to be working, but.. OS X gets stuck. Then i think, well maybe the NVRAM reset. Do the keys, turn it on again and stripes come up again. Tried the Open Firmware, stripes continue appearing. Almost tried everything but booting from CD. Has anyone had this problem?? Would appreciate the help. Thanks.
