Sorry for the stupid question -

Ive got a PowerMac G3 that uses PC100 SDRAM ... can I use PC memoery for this ?

Almost certainly. The early macs used proprietary memory (32 pin SIMMs, etc). If they call them PC100 memories, they'll be "standard". At least as standard as PCs. :D

People have troubles with incompatible PCxxx SDRAM memory in PCs.

Preferably take the machine in to the shop, and "buy if it works".

G3 Macs use the same memory as PCs. I use PC133 memory (Dick Smith) in my G3 Mac.

Im also wondering
Ive got a 60 Gb ATA 100 drive in the G3 (blue & white)
The MAC can see it fine but sometimes it freezes and Im wondering if its because its ATA 100 ..

Also (sorry about the 20 q's)
If I have 2 disks, and I copy the system folder of the OS drive to the other disk and make the non OS drive to be the startup disk, will the mac
boot ?

Each ATA channel can have two devices, e.g. hard disks. Make sure that one is set to Master and the other one to Slave through a little jumper usually between ribbon cable and power cable connectors. After copying the System Folder to the second disk, you can then select either drive as start-up disk. The only rule is that you can only have one System Folder per disk.
