Computer running very slow

How can I get my PowerBook G4 1.33 GHz to run faster?

Have done all the recommended things, like disc defrag, but it still runs very slow.

Can I install a faster processor?

Many Thanks

Billy.

Has the computer always run at the current speed or has it just slowed down? Ralph

How much RAM do you have? If you have 256 or 512MB, upgrading to at least 1GB would likely give you a speed bump. And as Josh mentioned, 10.4 Tiger is the preferred OS for a PowerBook...they will take Leopard, but Leopard is a much slower, bloated OS, and it definitely lags on older laptops.

If you have a decent amount of memory and are running Tiger, and the speed is unsatisfactory, it's probably time to make the jump to a MacBook.

10.5 would run fine on a 1.33Ghz CPU, the RAM seems to be the problem. If it is a DDR based mac, 266Mhz ram would slow it down compared to 333Mhz DDR PC2700

What OS is it running? I would suggest 10.4 for that machine, as it is a very capable OS, but it is also optimized for older machines.

Also a faster hard drive would help....

After you defragmented, did you optimize? How much free space do you have on your drive? As lemerise said a 7200 rpm hard drive would give you a nice bump.

What specific model do you have? Depending on which one you can max out between 1 and 2 gigs of ram. Also, if you specify which model, I can direct you to a fast 7200 rpm HDD which would increase speed.

Also do some software tweaks, such as weeding login items and checking for unnecessary daemons/background processes you can kill.

If you provide your model number we can help you a lot more specifically.

I would suggest updating your OS to 10.4.11 to start with. What software or hardware changes have you made in the last few months? What programs are running in the background and loading at startup? I don't know if any of this applies or helps but will eliminate possible causes. Ralph

There might be lots of junk files, system caches, log files, universal binaries present in your Mac and these files consumes lots of memory spaces. I would like to suggest , use any speed up Mac third party tool by searching over internet.
