I have a performa 6116 with sonnet nubus g3 at 500 mhz installed. I have two partitions on my hard drive (4.2 gb is the full capacity). In the one partition i have installed Mac Os 7.6 and on the other Mac Os 8.1. Since last week i have this problem: When i boot the Mac with the os 7.6, the computer continuously pauses for some seconds. This is happening everywhere, in the operating system, in the games etc. I erased the partition with the Mac Os 7.6 and i installed it again. I have the same problem. What can i do? When i boot from Mac Os 8.1 i haven't this problem. Everything runs perfectly.
