Hi Kappy Thanks for your answer. I did a reboot on my Macbook as suggested and this operation is going on non stop for 14 hours and on the screen always appears the same message that you can see in the picture in attachment. Any ideas?

Thankyou in advance for your help.
TerrenceHey terremo,
Thanks for the question. From the information you provided, it sounds like the iMac is successfully turning on, however video is not displayed. These symptoms can usually be isolated further by the troubleshooting steps in this article:

My MacBook Pro randomly froze during a sync to my iPhone and started making a scratching noise by the power button. I shut it off then turned it back on and it won't take me to the desk tops it will just flash a folder with a question mark in it. What do I do?
You have a HDD problem (hopefully you have a backup). Start with the information on this support article:

"Press power button for five seconds to re-start computer" sign????
I was using my computer and all of a sudden a black sign poped saying that I had to press the "power button" for five seconds to re-start my computer. I tried to ignore the sign but I couldn't. So I had to press the button. My computer turned off so I waited for a bit to turn it back on like I usually do. When it re-started, I had a new sign saying that my computer was turned off improperly. Is this normal? And why could this have happened?
Hi and welcome to the forum.
What you saw was your MacBook having what is termed a Kernel Panic. Information on what a Kernel Panic is can be found here:
*What's a "kernel panic"? (Mac OS X)*
http://docs.info.apple.com/article.html?artnum=106227
Should you be worried? If it happens often the you should have it looked at. Kernel Panics are often (not always) attributed to memory module faults but anything (hardware and/or software) can cause them.
If you do not get a Kernel Panic again then I wouldn't worry about it and carry on working as normal.

Sorry, possibly you need a new hard drive or try reformating. First
you can try something like http://www.alsoft.com/diskwarrior/ it has been known to repair disk that DiskUtility could not. YMMV and they don't give it away.
If Disk Warrior can not repair then you need to Reformate the drive. Make sure you have a back-up in place no matter what.

A few days ago my G5 started to freeze up while in use. It doesn't matter if in Safari, iTunes, Pages, etc. The cursor will not respond nor does any keystroke, force quit, escape, etc. I have to hold the power button down to shut the computer down. Then, try to restart. Sometimes restart will work and the computer will work for a while and then freeze again. Other times on restart, instead of the Apple logo at start up, I get a Zero with a line thru it, have to power off and restart again. When it does restart, the "spinning gear" takes a lot longer than normal to spin up and take me to the login screen. Have been told it may be my hard drive getting ready to fail. Have looked at disk utilities, S.M.A.R.T looks fine, "verified" and have verified disk, and repaired permissions. In case it is the hard drive, I bought external hard drive and hooked it up to Time Machine. The backing up to a long time, overnight, about 10 hours because it kept freexing up and I would have to shut down and try restarting again. Finally got everything backed up.
Any help or suggestions greatly appreciated!!! Could it be my hard drive is dying? Is the the normal chain of events or is it something else???Ok, to copy the Drive from one to another, get carbon copy cloner to make an exact copy of your old HD to the New one...

Believe it or not, anything on the Desktop uses 3 times the Resources of the Mac than if stored elsewhere, I can note a slowdown from just 30 items on the Desktop on a really fast Mac, so the less the better on the Desktop.
DW will not tell you about Bad Sectors, it's just the very best at Repair Directory damage & such.
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process. -
rMBP: Sometimes, after having been shut down, i have to press the power button several times before the machine starts up. It's 3 weeks old, and this has happened 2 times now. Is there something wrong with my rMBP?
Did you purchase the Mac new?
You have 14 calendar days from the time your items are delivered to initiate a return as noted here.
Even though you are past the 14 day limit, if it were me, I'd take the Mac back and explain what's going on. Your Mac should work out of the box.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.
Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

Pavilion dv6z notebook - shut down a few seconds after pressing the power button
Pavilion vd6z powers up for 5 seconds (I see the HP logo screen and the Windows startup asks if it should launch the Repair or Start Normally) then it shuts off.
I have removed the battery/disconnected the adapter and held the power button in for over a minute several times, removed and replaced the memory, blown the dust from the cooling fan & heat sink. I also have tried booting with the hard drive removed. The same issue exists if I have the battery in or not. After all of the these steps, the system still starts up and then powers off after just a couple seconds.
If I press ESC to enter SETUP, the system will still power off.
The warranty expired a few weeks ago and HP tech support can not help me...other than suggesting that I put a post on the forum.
Has anyone experience a similar problem and found a solution?Hello again visionpga.
If you've used known working memory and the problem still exists then you've ruled out many of the causes as you've tried testing all the hardware which you can test. I believe you're experiencing a motherboard issue which is likely a short. This repair is possible for you to do yourself if you have technical experience or you could have the notebook repaired by HP.
If you want to try repairing the notebook yourself I'll need your product number. This document shows how to locate the product number.
The US/Canadian number for HP Support is 1-800-474-6836. If you're in another country you'll need to visit HP Support Worldwide to locate the contact information.
If you have any other questions just let me know.

So just like last time I tried to update my iPhone software...MY PHONE IS FROZEN. Displaying iTunes icon and a USB cable I pressed the Power button and the menu botton together until the apple icon appeared held them down for 10 secs & NOTHING Now what? Do I just wait for the battery to run out?
Hi Careesa,
Your iPhone is in recovery mode-- you need to connect it to your computer and, most likely, iTunes will ask you to restore it. If you recently backed up this shouldn't be too much of a problem. -
my iMac won't boot up. I hear the chime and the Apple symbol appears but there is no whirling indicator that appears and after a while the computer screen goes black and the whole cycle starts again. There have been occasions when it has actually started and I have the dashboard appear but then the screen freezes
Since you have Lion v10.7.4 installed, use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

While I'm using safari, it will freeze up. When I force quit safari and reopen it, I find that I'm back to where I was when I did the force quit and safari remains locked up. When I try to restart the computer, I get a pop up that says that safari cancelled my restart. I then press the power button to shut down the computer. When I reboot the computer and open safari, I see all the tabs and windows that were opened when this issue began, only this time safari isn't frozen. This problem started yesterday.
Has anyone experienced the same problem? Is there a fix for this problem?Try Resetting Safari: Open Safari. Cick on the name Safari in the menu bar. In the drop down menu click Reset Safari.
