Mac pro wont boot no chime blank screen fan running 100%

When switching on the mac no chime happens, fans come on as normal then build up to 100% speed and all that happens is the light solid on the front and black screen, did the diagnostic on the logic board all that lights up is the orange trickle LED, i have done reaserch on this and aparently the riser cards have leds that light up when turning on the machine, i have also read that it could be a logic board needs replacing im really hope its not that and something else because they cost a fortune to replace. if anyone knows what is happening would muchly appreciate help
thank you

fair enough thought it would of been a logic board prolem i will try taking out the card and see what happens. if like you said it beeps do i need to replace the power supply ??
If it beeps with the video card removed that would mean it's the video card that is the problem.
I gave the computer a general clean last night but nothing major as in pulling out the cpu and giving it a clean, could that also be a problem ?
It's always good to limit the dust just to minimize overheating. But I don't think that the problem here. Just good maintenance.
also another question what are the symptoms of a logic board failure?
Machine does't work? I can't really be definitive. What happens if there is a logic board failure in your TV? I think you get the line of thought here.
thank you again you are being most helpful
You're welcome and good luck.

Help Mac Pro wont boot up

I have acquired a Mac Pro from a friend. It is an earlier model mac but Im not sure how early. My problem is, when I press the power button, the power light flashed and the built in speaker plays a really high pitched buzzing noise followed by a single low pitch beep. Sometimes it will stay powered on and other times it will just cut itself off. If it stays on the high pitched buzzing from the speaker will continue until you manually cut it off. It also doesn't display anything on screen...

If you bought the Mac from a friend get your money back. That high pitched noise and low pitched beep most probably mean the motherboard is hosed.

Mac Pro wont boot to logon screen

Help!!
A couple of weeks ago, before upgrading to 10.5.7, my screen would freeze like a picture with the mouse cursor able to move but nothing would respond. I generally had to use the main power button at least 5 times before the display would show anything and get to the logon screen. It seemed to happen when moving the mouse cursor to the top right corner of my display, which I use to "Display all windows". I have since updated to 10.5.7 but was still getting the problem. A couple of times the display just shut off on its own, there was a click within the computer then the display went blank. This has happened a few times.
Last night the screen froze again and I tried the usual reboot about 40 times and only a few times got the Grey Apple screen but would not get any further. If I had a blank screen on reboot the hard drive would be spinning at full speed and would not stop until I switched the machine off.
Now it has a mind of its own! If I get to the Grey screen it now has the sun ray symbol going round and sits like that for some minutes then the machine reboots and it goes through this cycle repeatedly on its own!
I can't get it to boot into the logon screen at all now.
I have tried various startup key options to no effect (no response to any startup options including PRAM, SMC, disconnecting all external items etc) and I am now at a loss as to what to do next.
Personally I think I have two problems, one possibly a faulty graphics card and secondly corrupted Operating System software?
Any ideas?
Thanks
Douglas

Hi Peter,
Thank you for your advice. It has taken many reboots to get it to recognise the install disk! Eventually it came up and I ran Disk Utility. It said the drive could not be repaired as Keys were out of order. I managed to install OSX on my second hard drive and I am now copying all the info I need from that drive after which I will reformat it ready for use again.
What a nightmare! Even worse are the negative comments I have read about the Seagate Barracuda 1.5TB Drives as I have 2 installed and also a couple of Lacie External 500GB and 600GB Drives which have also had bad reviews and I did have one fail and have spent years trying to recover 20,000 photos.
So looks like I am heading for another disaster down the line!
Thanks for your help with this one though!
Regards
Douglas

Mac Pro wont software update and a lot of apps keep freezing/crashing/not responding

Mac Pro wont software update and a lot of apps keep freezing/crashing/not responding Im on OSX Lion and i have a Mac Pro 1.1 please help

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

My Mac Pro wont power on please help

My mac pro wont start up.
I have already checked the power supply, fuses and have tried to zap the PRAM and changed the internal battery.
The on/off button is completely unresponsive and no light is showing on the monitor

To make progress, you need the fans to come on and the Chime. The conventional way to debug this issue is to remove EVERYTHING that could be drawing down too much power, and try for the chime.
Remove:
Graphics card
any other PCIe cards
Hard Drives
DVD Drives
external devices like USB devices
all but one pair of DIMMs
Then try to power it on. If it chimes, or the power light flashes, it's alive and can be debugged. Add back one item at a time and try for more.

Mac pro cannot boot after upgrade to 10.8.3

My Mac Pro cannot boot after upgrade to 10.8.3. Anything firmware I can reset or how should I do.
I am using a early 2008 Mac Pro

Can you boot into safe mode? http://support.apple.com/kb/ht1455
If not, how about Recovery? http://support.apple.com/kb/ht4718
If you can, run Disk Utlity and repair the disk. You can try rebooting normally, but I would just reinstall after quitting Disk Utility.

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it.

My mac pro wont start. I push the power button and I get a click sound. A few seconds later another click sound and that it. I've tried different power plugs. Going direct into the wall, through a power strip. By iteslf, with other devices plugged in. I removed hard drives, and some RAM, and nothing. Sometimes it would not turn on, and then some minutes later it works. So its was sparatic, but now its been the same situation for three days where it wont turn on.
I'm guessing power supply, but I wanted to see if anyone had a similar expereince and what the solution was, before I drag this beast to my local Apple store and have them look at it. Its a real pain to get it there and back and I want to be armed with some info for them. I already dragged this to them when it first started to do this, and of course it started up just fine for them. And you know if it works for the Genius then theres nothing wrong with. No matter what you explain to them.
I figure if anyone had a the same problem and was able to resolve it, I can relate that experience to the Genius even if it start up for them.
Thanks

Try a SMC Reset using the extended method:
Remove the AC power cord.
Press the power-on button. [This drains the stored charge from the power supply]
wait a quarter minute.
Restore the power cord, being certain to JAM it into the socket, as the big block of rubber inhibits proper seating.
wait a quarter minute
attempt to power on.
If no joy, examine the button battery half-hidden behind the graphics card. Remove it to measure the Voltage. A new battery should not cost over US$5, and measures a little over 3 Volts. BR-2032 is used in garage door opener controls and car door locks controls. The geeks at Radio Shack can measure it for you.

My mac mini wont boot from disk

My 2010 Unibody Mac Mini wont boot from disk, i need to open disk utility to repair my drive but it wont boot, any ideas?

HT4818 Boot from laptop's Windows Hard Drive in Mac Pro via Boot Camp

I have a work laptop that is on Windows 7. It's a work hard drive so I don't want to mess with it (particularly as it's encrypted). I basically want to use it on my Mac Pro rather than my piece of junk standard issue laptop when I'm working from home.
What I would like to do is pull the drive out, put it in my Mac Pro and boot from it using Boot Camp. Guidance I've seen so far talks about not being able to use an external drive but having to partition an internal drive. However, if I've got everything on a separate drive (i.e. my laptop's drive), will this work?
Thanks!

Thanks for the quick (and no nonsense) response!

Mac Pro 2006 boots into OS fine but graphics freezes on grey apple logo

When I boot my Mac Pro it boots into Mac OS X fine. I can access it remotely and all seems fine however the monitor only displays the grey apple with the whit background. I know the graphics card isnt over heating because I have removed any dirt/dust and had additional fans blowing the card and it is running cool.
does this mean the graphics card is dead? if so what can i replace it with as the machine is now 5 years old?
the current graphics card is a GeForce 8800 GT.

That last one is not a good sign. Kernel panic when starting from an installer DVD either mean you are using an installer version that cannot boot your model or there's a hardware problem.
I'm thinking your original thought may be valid. It would be provable if you had another GPU to try, but if you don't then I suppose you should replace the one you have. Of those available the ATI 5770 is an excellent replacement choice for both performance and cost unless you want to look for a different replacement card on eBay.

Mac pro wont let me install os x 10.6 from disk

mac pro wont let me install os x 10.6 from disk

You need the orignal system discs or an upgrade DVD that has Snow Leopard 10.6.3 on it and you must erase, or better Re-Partition, the drive to get rid of any Newer version of OS X first.
