Hi I have a G5 Mac, bought in 2004. with 1.8 Ghz, 256 MB DDR SDRRAM. We also have a second hard drive only used for storing music and pictures of about the same size, which has plenty of memory left. OS X 10.4.1 was running perfectly with no probs until last week when internet suddenly stopped working: Mac no longer recognised the Ethernet cable connection to our Belkin router. Router is working OK on other computers in the house via Airports. Network assistant tells me that 'another application has changed the settings' but will not say which application it is. In an effort to fix the problem myself I archived system software 10.4.1 and reinstalled 10.3.5. Problem continued, so I ran hardware check, which told me there was a memory error at start up 'post/0/2048'
Thanks, XXXXX XXXXX do I update back to 10.4 when I don't have access to the internet on the Mac? Can I unarchive the system somehow?
We have been trying the 8 point plan you suggest (selecting ethernet, TCPIP etc) but screen shows no IP address, no subnet mask, no DHCP client ID, Router blank. This was the result we got in 10.4, and then 10.3.5.
Have tried creating new account, but still no luck. The system profiler refuses to open so I cannot see if Ethernet hardware is listed there. Ethernet does not appear in the system preferences hardware list.
I upgraded to 10.4 via the internet, so do not have disks.
How do I zap the Pram? Thanks, K
