My MacBook Pro does not start all of a sudden upward

Hello

I turned my MacBook Pro yesterday and when I went to start it up again today, I pushed the powerbutton comes the startup sound and clear grey screen with an Apple comes up with a progressbar under. about a cm from the bar gets full and then a code appears on the screen for a few seconds, then the computer tries again to restart and it circulates in a loop. I took a photo of the code that is displayed for a few seconds and attached to it.

What should do?

I have timemachine copies the MacBook on my TimeCapsule, but I have no idea how to use when the computer refuses to start.

Try:

Try these in order to test your system after each see if it is back to normal:

1. a. reset the PRAM and NVRAM on your Mac.

b. Macs with Intel processors: reset of the controller (SMC) system management

2. restart the computer in Safe Mode, and then restart again, normally. If this does not help, then:

HD recovery start: restart the computer after the ring, press on and hold the

COMMAND and R keys until it appears the Utilities menu screen. You can also restart the

computer and after the ringing, press and hold down the OPTION key until the Boot Manager

the screen appears. Select the Recovery HD and click on the arrow pointing down.

3 fix the hard disk and permissions: at startup, select drive in the Utilities menu utility. Repair hard disk and permissions as follows.

When the recovery menu appears, select disk utility. After that the charges of THE select your entry from hard drive (mfgr. ID and car size) in the list on the left.  In the status area, you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is faulty or has failed. (State SMART is not reported on external drives Firewire or USB). If the drive is "verified", then select your OS X volume in the list on the left (subentries under the entry for the road), click the first aid tab, then click the repair disk button. If THE reports any errors that have been corrected, and then run repair disk again until no errors are reported. If no errors are reported, click repair permissions. Wait until the operation is complete, then exit FROM and return to the main menu. Select restart from the Apple menu.

4 reinstall the 10.10.5 update: OS X Yosemite 10.10.5 Combo Update.

5 reinstall OS X: Reboot of HD recovery Select reinstall OS X in the Utilities menu, then click on the continue button.

     Reinstall the 10.10.5 Update: OS X Yosemite 10.10.5 Combo update, if necessary.

Note : You will need an active Internet connection. I suggest to use Ethernet if possible because it's three times faster than wireless.

  • HP Pavilion p6-2054uk: HP Pavilion p6-2054uk does not start all of a sudden upward. Help, please.

    I hope someone can help here?

    I have a desktop HP Pavilion p6-2054uk (Windows 7 64 bit - i5, 3.00 Ghz - 6 GB of RAM) that I bought in 2012 and especially use of HP products.

    By starting my PC the other day, it will not start and crashes on the HP splash screen. When you press ESC, F10 and F1 and F8, it simply changes the screen to a black screen with 7 lines of text giving the details of my PC base on this subject. It should give me other optins at this stage, but does not work.

    The HP Pavilion p6-2054uk hard drive does not start even another hard drive OS I've tried from another computer with Windows 7 64 bit on it. Troubleshooting a few others, I even tried a fresh new hard drive in it with a new copy of Windows 7 64 bit to install into the CD Rom and it will not yet go through the HP start - that is abnormal screen since usually, it detects the Windows CD and install. Furthermore, fans in the PC work normal, as the eject the power of the PC CD ROM light is on too. I tried all the three available inside power cables and tried diferent nine cables sata/data and another monitor entry too, all to nothing done.

    The hard drive that was in the HP Pavilion p6-2054uk when he stopped to start up is fully accessible when placed in the other machine I have. Therefore, it is still operational.

    The notable thing only I did in the days before it were installing Adobe Creative Suite 6 but I do not think that it would cause a major problem like this, noting also that another hard disk OS (without Creative Suite 6 is installed) and a new facility wouldn't start either. Therefore, I am afraid a harware issue any.

    What could be going on here?

    Side for the second or 2 of optimism about the usual boot the PC normally makes noises, it looks like he died immediately after, suspended on the HP screen.

    Thanks in advance.

    AMD Phenom 9500 + 2.2 ghz QUAD

    RAM: 4 GB of Ram

    Graphics card: ATI Radeon HD 3850 512 MB

    Motherboard: AMD 690 G

    Yesterday, I was on my computer as usual and was on a server VOIP talk to my friends. As I'm holding down my push-to-talk button all of a sudden, my computer restarts and every 1-2 seconds in the restart it restarts again.

    It does not have any bios loading screen and nothing.

    I opened and cleaned everything but I could not find any problem. Any idea? It is literally on autoEVERY 2 seconds... he just constantly made the sound of a computer restart like as thought I would be pressing the button like a maniac.

    If it helps, I think my computer was on during the night and the following day until 02:00 so so well over 30 hours.
