First you need to run some maintenance (which in itself may solve it) to rule out software issues, so 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.

Red light logic board


Red light either means the side is removed from unit or there is a cooling issue if it is a G5 or newer. G4 or older that is normal.

2 red lights on logic board


I don't see that in the service manual. You should give some symptoms and details about the power on LED, fans PSU etc. You need to verify the PSU is good before you get to the logic board.

I have G5 PPC mac tower - power light is on, but the unit will not turn on. No fans are running. Just a bright white light on the power button.


First if side door or plastic shield is off, fans won't come on and unit won't start. Fans only run when unit is running hard and that's not always. Back to your original issue - not running, couple of things to try - first being side door and latch on back, make sure both are closed. Try restarting by holding start button on front of tower. If that don't cure it, disconnect power lead in rear for about 30 secs then try to restart.

Why does my desktop pro keeps shutting down unexpectedly


Just to clarify a G5 is not a Pro or "desktop Pro" (Mac Pro is an Intel based machine). Yours is a "Power Mac". Install a temp monitoring app to see the temperature (mainly the CPU temps). Mine runs around 50 to 60 Celsius and never more than 72. If the temps run to high she will shut down. G5 are great machines but it's not rare for them to go bad. Power supply issues and liquid coolant leaks are well know. Fans controllers have stopped working (the fans them selves are usually OK).

My isight g 5 will not start up, have the cover off


If your cover is off the Mac tower, it won't start, but the fans run really fast and the red light comes on. The plastic cover needs to be in place so that air flows the way apple wants to avoid overheating. The metal cover may also need to be in place as well.

MAC PRO dual2.3- freezes, gray screen crash, freeze with hi fan mode,kernel panic reports, all require start button shut down. Some forums suggest ATI card failure. I'm lost.


All computers will shut them selves off or crash when fans are failing, or have failed. Cooling fans are plugged into the motherboard, and firmware on the MB keeps track of the system fans, along with everything else. If a system fan is failing, or has failed, the signal is sent to shut down. Some PC's will shut down cleanly, others give error messages, and some just freeze up. Of course, Bad RAM, video cards, and hard drives with bad sectors, can also cause problems like you have discribed.
I would write down any error messages, and beep codes, and then look them up online for a place to start.

PM G5 has red light at front before switching on


It could be your motherboard but I would first try a Apple hardware disk and run the diagnostic tests.  If you can't boot from the DVD you could try a PRAM reset.  I have seen other weird issues with the hard drive not mounting which causes the fans to run loud.  The Apple Diagnostic disk comes in your original software pack and its usually on the 2nd or 3 DVD.  Sometimes the CPU speeds get out of whack and they need to be recalbrated.
