Sounds like you might have an incompatible driver consuming all of the CPU cycles. Try this: Open the process viewer (In the applications folder). Look to see what process is consuming all of the processing time. I had the HP driver for my HP PhotoSmart 1115 would slowly slow down the machine until the HP Communications app was consuming 99% of the CPU time. Alternatively you can open a terminal window and use top. Bob. Lacy Kyle wrote: > Please, please help. I have a bog standard 450 cube except for 448M > ram.
