PowerBook G4 won't update Leopard

[iHateMacs]

Hi. I have Leopard 10.5.4 installed on my PB G4

When I try to update the OS it will download a 600+mb update then say the computer needs restarting. I let it restart then it displays a progress bar on top of the default Leopard desktop image.

The bar will go up about 1/4 inch but never any further. I have tried it a couple of times but it's always the same.

If I switch it off and back on again it restart in 10.5.4 normally.

Any suggestions? I have 2GB ram and about 130GB free on the hard drive.

Have you tried the Combo installer for 10.5.6 yet?

Wow, four months since the last released 10.5.x update.

No I hadn't tried that. I will give it a go. Thank you

It this update 4 months old? The Laptop has probably been in it's case for 90% of the last four months
