Desktop icons blink on and off; computer won't boot

I was recently trying to view a quick time file on a dvd when I got the message that some components may be missing to view the file. I downloaded the components from Avid and put them into my quicktime folder (Library>>>Quicktime folder).
When that didn't work, I removed the older component that had been in the folder and tried to to view the DVD again. This time I was unable to even open Quicktime. I tried to return the "old" component back into the Quicktime folder, but kept getting an error message. Something along the lines of "an unexpected error occured."
I then attempted to reboot the computer. That's when the trouble really started.
My computer now gets to my desktop; all the icons blink on and off, and then the computer seems to try and try to start. I assume that the component I removed was in the start up sequence, but a) I don't know for sure, b) I, of course, can't get on to find out, and c) even if that is the problem, I don't know how to fix it without getting that error message.
Has anyone experienced this problem? Any thoughts? All assistance will be HIGHLY appreciated. Thank you.

Restart your machine with the Command and S keys held down, and enter the following commands:
mount -uw /
mv /Library/QuickTime/ /Library/QuickTime_old/
exit
Your computer should then continue the startup sequence; if it finishes starting up, the components you installed were responsible for your issue. My own /Library/QuickTime/ folder is empty, so the folder doesn't contain anything critical.

Hi all,

What happens when you try to boot?

HP pavilion 751n desktop recently replaced motherboard and now windows won't boot up.

Keep getting the screen asking to start in safe mode etc. Tried using the recovery cd to reinstall all of the programs but it says I can only use this on an HP pavilion, I'm guessing because I replaced the motherboard it is not recognizing the computer as one. Any way around this or is there something else I should try first? Running windows xp.

Hi… I don’t this has anything to do with Network Name or old Wireless Network connection. Might be some of the system files are missing or gone corrupt. I would suggest you boot the system in safe mode and restore the system to a restore point dated 15 days back. This will help you to boot the system in normal mode.

Computer won't boot up after installing SIIG card

Hey Everyone,
I having problems with my SIIG FireWire 2-Port PCIe DV card that I've installed into my PowerMac G5 Quad. With the card installed the computer will not boot up, which is the same thing that happened with my previous two models of the card. I installed a new card yesterday and it worked fine all day, but after shutting the computer down for the night and then restarting it in the morning I am experiencing the same problems. The light on the front of the computer turns on, but the screen does not, and after about a minute a loud fan noise comes one. I have the card installed in Slot 2. In Slot 1 I have a ProTools HD card and in Slot 3 I have an AJA Kona LHE card. Even with all of the cards removed the computer still does not boot up. Anyone seen this problem before? Any help or information anybody can offer would be greatly appreciated.
PowerMac G5 Quad Mac OS X (10.4.8)

Hi, I had the same problem with my dual core G5.
I installed the card and my computer won't boot up. The screen stays gray and the fan keeps spinning.
I contacted SIIG and they said the card is defective, which, I doubt it is.
I then returned it for a refund.

Mac Mini desktop folders/icons and top menu blinking on and off

Hello. I've just returned to my Mac Mini after being away for a few days. Upon booting and having the desktop fully load, I have been experiencing all folders/icons and top menu bar blinking on and off every ten seconds. I have only opened Fire Fox to try and diagnose why this is happening. No solution yet.
I am running Snowleopard with Mavericks and I'm aware Mavericks is a little buggy at the moment (beach ball used to blink on and off every now and again and performance has gotten slow) I only have the HDD replaced last week as the last one failed. I really need to fix this problem soon as I rely on my Mac to work from home.
Any help would be greatly appreciated

I have sovled the problem! for now at least. I came across another users suggestion to dissable "sync status icons" in google drive as it confics with the finder in Mavericks. I guess this would only work with others having this problem with Google Drive and Mavericks.

The CRT won't come on and the computer won't turn off. ???

Hi all,
I just got another free Rev. A iMac CRT today - it was in an old, abandoned school and the people who were moving everything out of the school thought it was dead, so they gave it to me. I tried starting it up, and it wouldn't turn on. When I took off the back to see if it had any good parts in it, it turned out everything was unplugged in the back, so I plugged it all back it. It worked great, I was deleting the school's files and apps so I could sell it, until a few minutes ago when I tried to wake it up from sleep. The display just wouldn't come on. I though it just wasn't waking up. I tried typing on the keyboard and clicking the mouse, and I finally pressed the power button on the keyboard, when I heard the normal beep it makes when you press the power button on the keyboard and it gives you the dialogue box "Do you wanna turn it off, restart it, etc?" I thought, "this is weird, why isn't the display on?" So I pressed the enter key, figuring that Turn Off was the option selected and that the display would come on when I turned it back on. Sure nuff, the computer turned off. I waited a few seconds and turned it back on. The display still wouldn't come on. I waited a few minutes til I was sure it was all the way booted up. It won't respond to the keyboard, the mouse, repeated jabs in the reset button on the side, or the power buttons on both the unit and the keyboard. I held down the power button for an entire minute and the display won't turn on and the computer won't turn off.
This is totally bizzare. Does anyone know how to a) turn on the display or b) turn off the computer? It's looking like I'm going to have to unplug it and try again later.
By the way, it's running 9.2.2, like the one in my signature line.

I finally pulled the plug and restarted and it's working fine now. Does anyone know what happened? I think it could've had something to do with the PRAM battery; every time I've started it up it's said the date is January 1956 and the time is 9:55. hmmm...
Edit: I just realized that in addition to the date being 1956, the hard drive was completely randomly renamed to "k hortdpc." ***???
Another edit: I just realized I probably renamed the hard drive in my frantic random clicking and typing - I probably accidentally clicked the hard drive name and randomly typed a new name in my attempts to wake up the computer. oops

Hi I just upgraded software through iTunes then unplugged iPhone now it is stuck on the connect to intunes screen, it won't turn off and iTunes and my computer won't recognize my phone? Please help

My phone is doing the same thing. My computer acknowledges that I have connected my iPhone 4, however, iTunes will no longer connect or sync to my iPhone 4. I have uninstalled iTunes, Bonjour and all Apple products from my pc. I have re-installed them back on. I have reset my phone. I have emptied my temp folder. I have done everything. If my iPhone cannot update and sync with iTunes then I may as well get another phone from somewhere else. I am disappointed that I cannot resolve this issue.
Rebeccaspe31, were you able to resolve your issue? If so how?

I spilled a little bit of soda on my keyboard ( more like big drops) and my computer won't turn on but it will still charge. After i spilled it it kept trying to turn on and off by itself until i finally just shut it down

I spilled a little bit of soda on my keyboard ( more like big drops) and my computer won't turn on but it will still charge. After i spilled it it kept trying to turn on and off by itself until i finally just shut it down. Today i tried to turn it back on ( i spilled it last night) and now it won't turn on but when i plug it in the orange light comes on so it still charges.

TBF: You may have been lucky enough not to cripple your MBP immediately with your spill, but a spill such as you describe will have left obvious traces if you ever need to take your machine in for a repair of any kind. And as soon as evidence of the spill is found, any chance of the necessary repairs being performed under warranty will be gone.
Taking the machine in now to be cleaned and have the greasy parts replaced will be expensive, but doing so may save whatever remains of your warranty. For a price, Apple will restore the machine to like-new condition, and at the very least, you will then have a 90-day repair warranty on it. If you have significantly more time than that remaining on your original one-year warranty, and especially if you've bought the extended AppleCare Protection Plan, it would probably be worth taking the machine in to a Genius Bar for a look-over. Ask whether, if you have Apple clean and repair the machine now, your new-computer warranty and AppleCare plan will be reinstated afterward or whether all you'll have is the short repair warranty from now on. If the spill will negate your warranty and AppleCare even if you have Apple clean it, then the cleaning probably isn't worth paying for. But if paying for the cleaning will get your warranty and AppleCare reinstated, it may be worth doing.

Hello Bricky2013,
The following article has some useful tips that can help stabilize your iPhone.
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

When I logged on all of my desktop icons were missing and I wasn't able to open any programs. I had to reboot three times to get everything up and running. Any idea what caused this?

When I turned my computer on this morning, all of my desktop icons were missing and I wasn't able to open any programs. I logged off and logged on 3 times before it was all back to normal. ANy idea what caused this? Thanks!

Nope!
When posting in Apple Communties/Forums/Message Boards.......It would help us to know which iMac model you have, which OS & version you're using, how much RAM, etc. You can have this info displayed on the bottom of every post by completing your system profile and filling in the information asked for.
This will help in providing you with the proper and/or correct solutions.

I am trying to download a variety of files and when it is finished, the Mac freezes up and the task bar continues to blink on and off. I have to go into Firefox and actually quit the application to continue. Any help is very much appreciated

I am trying to download a variety of files and when it is finished, the Mac freezes up and the task bar continue to blink on and off.

are you backing up files, or doing a Time machine backup, either way, the Time machine will STOP when finished and show "last backup at XXXXXX" meaning its done...... OR if when transferring files, it will show a progress bar on your desktop and vanish when files are copied.
Open up the Hitachi drive (your G drive is made by Hitachi, and the best made by the way).....and see if the files are there.
a MORE VISUAL way is to open the hard drive file, and drag and drop files INTO the Gdrive and you can see them visually be copied there as you do it.
To see your HD on your desktop GOTO FINDER......PREFERENCES....then GENERAL TAB.........check the box marked HARD DRIVES.........then your Gdrive will appear on your desktop........open it from there, and DRAG and drop files from anywhere INTO the Gdrive....... easy visual way to see the files being copied into the Gdrive.

New iPod touch blinking on and off repeatedly

I just bought a new ipod touch today, and once I plugged it in to my computer, it showed the apple logo, but then the screen went haywire by blinking on and off. When it's blinking on and off, the screen looks frozen.
I've hardly touched it, what do i do? Someone please help. (please spare me any sarcasm)

Actually, after I got the iPod Touch replaced, it had the same exact problem, which I suspect that I'm just very unlucky because my computer is relatively new. I've been trying to figure this out for weeks.
I did take my iPod back to the store where the associate talked down to me and kind of made me feel stupid (on their computers, nothing is wrong..but at my house, it's pretty much cursed) ..so yet again, I am trying to get the iPod replaced and figure out what is wrong.
I also tried calling, addressing two problems (one of which is irrelevant). They pretty much gave no answer for this question. They told me to restart it, but as I said, no button works after it shuts off.
