Macbook doesn't want to sleep

For info, I have a 2006 Macbook running Snow Leopard. Whenever I put my Macbook to sleep, it keeps waking itself up. I tried the ethernet solution, resetting PRAM, even disabling the Bluetooth device. They've been short fixes but end up coming back a while later.

For the record, Bluetooth is listed as "unavailable." To add, I don't have anything plugged in barring my charger.

Also, this showed on my console, the bolded parts are interesting:
