powermac g4 driving me crazy

[daveparki]

i bought a powermac g4 mdd 1.25ghz single cpu off ebay , was working ok but has started to mess me about, wont wake the display when put to sleep , and crashes or goes slow on internet, intermittently i might add, i have run the techtool program and shows ok, using same connections as my mac mini , but still giving me grief(do not have a apple hardware test disk) so cant try with that, any assistance would be greatly appreciated, regards

system restore?

No such thing in Mac.
I would suggest doing a permissions repair and following the other suggestions in THIS THREAD


There are plenty of other helpful threads like that one. Take a look and you might just see. :black:

trying but failing

tks for responce, looked at the thread, i have been looking at the same responces for about 5 days now, my problem is........when i tried to boot into single user mode, i would not , just went to the osx screen(tried loads a times) so could not do nothing that way , verified and repaired permissions, said drive and permissions were ok, i do not have an apple standard keyboard and could not find out which was the option key to reset the pram, ..............so now my mac powers on, hard drive is motionless unless i put it in the ata66 socket, but which ever way i put it the display will not power up so cant go any further, regards

sorry i meant to say the mac would not go into single user mode, regards

The inelegant way to reset pram is to take out the PRAM battery (the 1/2 AA battery on the motherboard). You don't need to know which key is which for that.

 

[daveparki]

done that a hundred times and pressed the pmu reset and guess what ........ nothing happens, but cheers for your responce , regards

Do you have an OS X install CD/DVD? If yes, try to boot from that, and check your harddrive with Disk Utility.
Or, alternatively, boot the PowerMac in Target disk mode (press T while booting up until you get a big yellow Firewire logo on screen) and connect your Mac mini to it with a Firewire cable. It will mount and behave like an external drive, so you can try to repair it from there.
The symptoms you describe can be caused by a faulty disk structure, or bad RAM. There is an OS X version of Memtest, try to get it installed, and let it run at least 3 times (will take quite some hours). It's the most thorough test for memory.

I think Avalon is going in the right direction. Sounds like your hard drive is wacked out. Remember, a hard drive's life span typically is about 3 years. I've changed hundreds in my store. Heat is a major enemy of a harddrive. Many years of heat can warp the platters and make your harddrive do some funky things. I wouldn't even do a disk utility come to think of it because a failing harddrive is never consistant. It may do well for a couple hours. Then it may fail. Never know with a damaged one. I would just purchase a new drive, install a fresh osx.
