If you could be a little more descriptive about where your mac is stopping (what screen looks like) I could be of more assistance but here is a point to start at...
Start here...  
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
 
Mac OS X: How to start up in single-user or verbose mode
 
If that doesn't help, try booting into Safe Mode and see what happens, if it comes up hopefully another restart may solve, if not, you can at least use this as a starting point to try and resolve. Safe Mode will allow you to get around, surf, etc...
  
What is Safe Boot, Safe Mode?
  
Mac OS X: Starting up in Safe Mode

If Safe Mode comes up alright, I would install AppleJack, excellent troubleshooting article can be found here... Troubleshooting Tools: AppleJack
 
Another excellent free tool for performing maintenance is Onyx (be sure to download the right version for your system). Install the package, then run it, it will check your drive and the structure, after this, click on the automation tab and check on everything for Maintenance, Clear Cache, Cleaning, and check on Reset -> LaunchServices database and Mail's Envelope Index. When it completes, restart. Repeat any time something seems flaky, if not try to run at least once a month.

1.Try a Safe Boot
Mac OS X 10.2 and later Safe Boot includes disk checking and repair. First start your Mac in Safe Mode. To do this, shut down your Mac. Now Turn on your computer by pressing the power key while holding down the Shift key. When you see the Apple logo, release the Shift key. After your Mac fully starts, restart your computer normally without holding any keys/buttons during startup. Note that Safe Boot is slower to boot.
2.Run Disk Utility
Turn your Mac off by holding down the power button for a few seconds. Turn on your Mac and hold down the Command and R keys until you see the Apple logo. Then you should see a "Mac OS X Utilities" window. Select Disk Utility, click your OS X hard drive and select verify/repair disk.
3.Reset PRAM
This may fix your boot failure. PRAM ("parameter random-access memory") stores some of your settings. You may reset PRAM. To do that, turn off your Mac. Now turn on your Mac. Then, immediately, hold down the Option-Command-P-R keys until your Mac restarts. When your Mac is starting up, release the keys.
4.Reinstall Mac OS X
If nothing above works, you may try this. Your Mac needs to be connected to the Internet. See number#2 above. Follow the same steps. Restart your Mac and hold down the Command key and the R key until the Apple icon appears; when you see the Mac OS X utilities window, select the Reinstall option.

Power mac g5. Although I show Ethernet connected, i can't get network


You've established that you have a working physical connection. But your network addressing and routing is apparently not setting up.
The usual configuration is to set your Mac to "Using DHCP" and your router or other network interface to provide DHCP addressing. (If the address that shows up in the window on your Mac starts with "169..." it's a bogus address that means your DHCP isn't coming through.)
The most likely culprit here is your router. Take your router out of the chain or command entirely and plug your Mac directly into your network interface (assuming they are not the same box) and see if things suddenly start to work. If so, follow the configuration instructions that came with your router until you get a working connection through it.

I have a Mac G4 desktop. It froze up so I restarted using the power button and when it came up it had a blinking question mark inside a folder. It will not do anything even after restarting several times....


This means the mac can not find the system to start up, you can try holding down the alt key as you start the mac, this may bring up a choice of systems to boot from if not then try holding down the shift key at startup, as this will boot without extensions loading. If none of this works then you need the startup dvd that came with the mac, if you dont have it the you need a retail copy of the mac os that will boot your mac , if its g4 then osx 10.3 or 10 .4 will work.

cheers

My Mac desktop, justa couple years old when i turn it on, the white screen comes up and after a few shows folder, with a question mark. The icon blinks, but nothing happens, mouse doesn't work either


Mac can't find the system to start up as usual, if you have the dvd that came with it (or any retail mac os dvd) start up from that and run the disc utility which will hopefully repair your disc.
If you have not the dvd , then do this start up the mac holding down apple and s keys , you will get a black screen and white text. You are now in the system firmware and you have to careful here!
wait a mo press return once, then type
fsck -f
press return once, this will force the firmware to check the disc.

if this goes ok then try restarting normally.

hope you helps
thanks for using FixYa

Mac mini will not produce video


Hi, Sorry you are having problems,
Well, that sounds pretty bad. Does the Mac make the start-up sound when you turn it on?
Does the little light in front turn on ?
Do you hear the hard drive spinning up and working to boot the mac ?
So, if all these questions are answered Yes.... sounds like the video connection has blown.
If you say the Mac is almost new, Apple should cover this with the one year warranty.
Good luck.

Mac os x won't eject disk


Shut down the Mac, and then start it up again, holding the primary key of your mouse down. That commands the Mac to eject any discs. It should work just fine.

Try the cables. Push them in as far as you possibly can.
