iMac G5 (Rev. A) fan goes high speed when asleep, and takes forever to boot.

[MaxSolar0713]

Hello whosoever.

I have an iMac G5 (Rev. A, PPC. 1.5 GiB RAM) of which has 2 problems:

1. If I start up OS X 10.5, it takes a LONG time to start up. Now, I also have a partition of OS X 10.4 on a different disk partition, and its boots up in something like 30 seconds. The Leopard partition used to do the same.

2. If I put the computer to sleep, sometime in the near future (like 2-10 minutes) the fan will go at full speed, the power LED stays the same, the computer doesn't wake up, etc. Rebooting it gets it back to "normal" of which it will boot, but it still takes forever.

I recently replaced the original 160GiB hard drive with a 1TB hard drive (SATA, 7200 RPM, Seagate.), however, the problem did not show up until about 2 weeks after.

I have been using some other peripherals with the computer including:

- A USB Hub.
- A SATA/ATA-100 to USB adapter.
- An External HDD (USB, Seagate, 500GiB. Appears to connect by USB to SATA to the drive, not directly USB.)

The only settings I have modified are File Sharing and Display settings.

Any suggestions?
