Help with updating my MacBook

Hi

I have a macbook 2,1 with OS 10.4.11. I haven't updated the system or any software since I bought it 4 years ago. I run Pro Tools and recently Ableton Live (7) on it but recently it's started freezing and not working very well for either program. Pro Tools I constantly get error messages and it sometimes won't even play back tracks - saying the following for example:

The operating system held off interrupts for too long. If this occurs frequently, try inceasing the "H/W Buffer Size' in the playback Engine panel. (--6086)

With Ableton I tend to get the spinning wheel and it freezes and I have to force quit.

I use a 1TB WD external hard drive to record.

My processor is 2.16 GHZ on an Intel Core 2 duo and I have 2GB of memory Bus 667 Mhz DDR SDRAM

Do you think it would be a good idea to update my OS or would that make things worse?

Thanks in advance for any help.

Moved to correct forum. Doesn't really belong in Music.....

Your MacBook is a bit dated and you're running Tiger which is now 3 versions behind the latest Lion. Unfortunately, you can't put any more than 3 GB of memory in that machine, however, I would upgrade to Snow Leopard and max out the memory. That may help to speed things up somewhat. You might also think about installing a faster larger internal hard drive. Perhaps a 500 GB or 650 GB 7200 RPM model.

You'll need the boxed version of Snow Leopard which Amazon has for $119. To get to the 3 GB of memory, you'll need 1 each 2 GB module and 1 each 1 GB module. Check with Other World Computing on the web for memory and hard drives.
