Computer not fully starting up

I have a PowerMac G5, and just recently my computer will start up to the gray screen, yet it will remain there, and usually around 30 seconds later, my fans start blowing like crazy. I have shut off my computer and rebooted it with several different methods: holding down command-V or rebooting the pram my holding down command-option-p-r until the tower restarts but it will all inevitably go back to where I first started- at the gray screen frozen, with my fans making more noise then ever. Any suggestions? I'd really appreciate it. Thank You!!!

what would be some reasons why my hard drive/logic board would start dying out of nowhere? Are there any solutions?
Not out of nowhere really, as we ourselves are set to expire at sometime... so is everything else, including Computers, some go longer than others.

Computer wont fully start/Windows will not load

I have a Toshiba Satellite A305-S6905, and was having a few issues with it. I read on the Toshiba Product Support how to restore my laptop to the 'out of box state'. While doing this it encountered an error and shut down, I saw people saying that this was due to a hard drive issue and that it needed to be replaced. I replaced the hard drive, and still have no luck getting my computer to fully start up. I tired to install Windows Vista Ultimate, and everything was going fine until the last step where it froze and shut down. Now when I start up my computer it says "Windows failed to start" and gives me all the start up options. When I select 'Start Windows Normally" it goes to the screen with the green loading bar that says "Microsoft Corporation" underneath it, and will go no further. When I select Safe Mode, it stops and hangs after it loads windows\system32\crcdisk.sys and will go no further. Any assistance will me much, much, much appreciated, thank you!

Best to restore the hard disk to its original out-of-the-box contents using Toshiba recovery media. If you don't have the discs, obtain them from Toshiba.
Order Toshiba Recovery Media
I replaced the hard drive
Please give us the full make and model of the drive you used. (Some with advanced-format technology are troublesome.)

Ipod touch 3rd Gen not fully starting up - constantly restarting with the apple logo screen

Hi,
First of all, I cannot get my ipod touch (3rd Gen) to start up so I cannot get model specifics and version numbers - though it is iOS 5.1.1
I have obviously tried to restart it by holding the power and home button for 10 secs but this has not done anything.
At the moment, the ipod switches on and I see the black screen with the white apple logo - this stays on for about 3 minutes, then I get the little spinning circle (but it isn't spinning) for a couple of minutes, before it powers off and does this again... repeatedly. It only stopped because the battery power ran out.
I have connected it to my computer with the latest version of itunes - it appears in the devices list but just has a spinning 'loading' icon and is grayed out. As my ipod restarts the cycle again as above, my computer makes the noise as if i just plugged it back in and the above happens again in itunes.
The problem began when I updated apps (through update apps in app store) and it froze - I turned the ipod off to restart it, and now this is happening.
Any help or advice extremely grateful... I can't even access it to get it restored which is a bit of a problem as I have work notes on it. (Obviously I don't know if notes are backed up on ipod backups through itunes?)
Many, many thanks in advance!

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Macbook not fully starting up.

My Macbook, which I have been happy with until now, isn't starting up fully. I get past the Apple screen with the clock and the chime, and it starts OS X. I try to log in to my username (Macbook is password protected), and it will show my background, and stop. It will eventually do the rainbow spinning ball thing, and just sit there. It is starting to upset me, because I haven't bumped it or hit it or done anything that would have caused physical damage to it. I installed a new hard drive about 3 weeks after I got it, which was in August, and it has had no problems until now. The RAM is OEM, and I haven't done anything else to the computer. What is wrong with it?
Right now, I'm trying to Repair the disk permissions, and its frozen again, with the spinning rainbow ball. I'm honestly happier with my PC than I am with my mac.

Try running fsck once.
1. Reboot/Startup holding your Command-S key down.
2. At the command line type the following and hit 'Return.'
/sbin/fsck -fy
3. After it has check/repaired your disk, type 'reboot' and hit 'Return' again. Unit should bootup normally.
If that doesn't work, the only commercial repair utility that's compatible is Tech Tool Pro. DiskWarrior hasn't been updated. Last resort is a reformat.

Uninstall norton causes computer not to start up

I have just bought a toshiba all in one PX30T-01Q today and trend security software. When I tried to install trend it says that norton is incompatible with trend. It asked if I wanted it uninstalled. I clicked yes so it went about uninstalling it. But then my screen freezes. I had to turn it off. Now I cant even start up my computer. HELP!!

This is the site for U.S. Models only and yours appears to be an Australian model. Your support including Tech Support phone numbers can be found HERE. The first thing I would do would be take it back where I bought it. If that is a problem, then call Tech Support.
One thing you might try before doing all this is to turn the machine on and if it freezes as before, hold down the power switch for 10 seconds or until all lights are out and the fan stops. Then turn it on again. Good Luck!

Not fully starting up w/ black screen & no chime

My 15 month old 17" MacBook Pro decided to go to sleep this afternoon and never wake up. Had to hold down the power key to turn it off, but after that point, whenever the power key is pushed, the light immediately comes on in the front and it makes a slight sound (similar to waking from sleep).. no startup chime, and the screen remains black.
I have tried resetting PRAM, Power Reset, changed out ram to the factory stick, and even trying to target disk mode it to my wife's iMac in the hopes I could pull off the most recent data.. to no avail. (wouldn't even show up). I tried to boot from the 10.5 disc and it just got stuck in the machine and wouldnt see it (though I can hear it spinning up in there when I attempt a restart)
I have never seen anything quite like it in my years of dealing with Macs and it has me quite perplexed. I have trolled all the forum posts that include "not starting up" and have tried every trick mentioned. Suspect is the hard drive at this point, but the Logic Board keeps coming up in posts so I am not ruling that out. I have an insurance policy that may cover this but I am trying to revive it before resorting to that (or driving 2 hours to the nearest Apple Store)...
Anyone have any other suggestions? I would try a key on a kite in a lightening storm at this point if I thought it would help (though I suspect that power surges/outages we have had here the last few days are the culprit since it was not even acting any different until a few days ago.. even though I have it on a UPS) Help!

Are you sure the screen is totally black? My Core Duo MBP started up to what I thought was a black screen. when I turned on the overhead lights I could just barely see something on the screen. When I used a bright flashlight I could seee that my desktop was there. The problem was the backlight going out. This is repaired by replacing the inverter.

Could not fully start the application because an unknown error occured

I'm using photoshop 7.0 and my problem occurs with Imageready. I am using Vista, but this has not been a problem for the past year (so I don't think it's Vista related).
I recently created an animation in Imageready and it worked just fine. However, when I returned to use Imageready again, I received the error listed above.
Reinstalling does not resolve this problem. If I do a system restore, I am able to use Imageready again. . . but only one time. after which the same error occurs.
Anyone got any ideas?
Thanks,
John

Any securtity tools or specific Windows updates? Something is most likely suppressing the app. Also check the properties of the executable for ImageReady. It's possible something has reset security permissions or activated DEP for it. Run it in compatibility mode, if need be...

RAM INSTALLED BUT COMPUTER NOT STARTED

RESPECTED SIR,
I HAVE G6-2312AX HP PAVILION NOTEBOOK /LAPTOP. WINDOWS 8 INSTALLED IN IT. 4GB RAM ALREADY THERE. NOW I WANT TO ADD 4GB MORE. I PURCHASED 4GB DDR3 1600MHZ RAM AND TRIED TO INSTALL IT. BUT COMPUTER NOT STARTING. KINDLY TELL WHAT TO DO. JAI HIND
This question was solved.
View Solution.

It sounds as if you did not put in a pair of identical memory modules or did not use guaranteed compatible memry modules. You can't use the module that was already there unless the one you are adding is identical in all respects.
Only use guaranteed modules in identical pairs if you want your memory upgrade to work right the first time.

Trying to sync selected (greyed out) contacts to my replacement 4s. Get error messages - computer not setup to sync - override or OK. OK - session could not start. How do I fix?

I have a new replacement 4s. I am trying to set it up. I hate iCloud but need it to sync my calendar to my phone. I mistakenly set it up to sync Contacts too and found out it synced ALL contacts which I do NOT want. I used to use iTunes to sync only selected contact folders (one I call Sync). Others are too sensitive to have on my phone. So I turned off "where is my iPhone", and turned off "Contacts" on iCloud. It said it would delete all my contacts on my phone the next time I sync (using iTunes). So I try to sync my Contacts using iTunes and find that under "Info" on the device tabs my only possible selection is ALL contacts with the "Selected" button greyed out. But even leaving all checked, I get the message "iTunes cannot sync information with the iPhone because syncing has been disabled on this computer (my Mac). Do you want to enable syncing?" I hit the button "Enable syncing" and I get the error message "Syncing cannot be enabled on this computer" with "Override" and "OK" my choices. If I select "OK" I get the error message "iTunes could not sync information to the iPhone (Name) because a sync session could not be started". I can sync my music and my apps but get this stupid message otherwise. What gives and I do I fix this? Thanks

Actually I can't sync anything - no music, photos, etc. And it tries to start syncing as soon as I plug in my iphone and itunes is open. It ends "sync" but hasn't done anything. I have tried deleting lockdown files (per "solution" found here). I have deleted all my backups (per other "solutions"). I have restored my iphone 2x. I have done soft boots of my iphone. My macbookpro 10.9.3. iphone 7.1.1. iTunes 11.2.2 (3).

When I start iTunes on my home computer (Not a MAC), it automatically shuts down, and gives me the message that the Data Execution Prevention security feature has shut it down...what to do?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it, which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

If my computer is not fully charged but i'm shutting it down for the night, is it better to leave it plugged in or to unplug it?

If my computer is not fully charged but i'm shutting it down for the night, is it better to leave it plugged in or to unplug it?

Your computer will not overcharge, even when off. If the battery is sufficiently low, it will top off the battery and stop charging. By morning, the light will be green because it is done charging.
There is no need to disconnect the power when you shut it off. The SMC microcontroller will continue to supervise charging the battery, even when the main processor is shut down.
