I understand that your display just went black. If you restart the display remains black with a blinking cursor, but with no error messages. You do hear the fan and hard drive spin up.
Here are two links to assist you with this difficulty.

A60-155: Operating system will not boot.

I have a TOSHIBA A60-155. when i turn on the laptop it willnot load the operating system, i have read the manual and apparently it is failing the self test i have tried selecting all start up modes but nothing will work. I have not yet tried any Recovery cd's. The problem started after i pressed the power off because the computer froze. Does anybody have the solution to this problem???
I would also like to know what BIOS is and do i have to upgrade it? my laptop is about six months old.

Hi Ben,
Firstly, you should not need to update your BIOS if your notebook is only a few months old.
Secondly, The start sequence of your notebook is a three stage process :-
1. The POST will check the functionality of your attached peripheral resources, HDD DVD etc.
2. The BIOS will then load and deal with the allocation of RAM etc and also initialise the basic system functions of your notebook.
3. The BIOS will read the Master Boot Record to ascertain what operating systems you have installed and will then either load the required system or give you a menu of possible options from which you can choose.
If you press the ESC key as soon as the power on process starts you should see the results of the first two steps (The POST and the initial BIOS load).
The fact that you see the selection menu offering the choice of load types (i.e. Safe Mode etc.) would suggest that your system cannot load your operating system from the hard drive. The fact that none of the available options work indicates that there is a basic problem with your hard drive.
If you have a bootable CD then I would suggest that you try to boot your system from the CD (Press and hold the F12 key during the initial power on sequence and then select your CD drive from the list).
Alternatively you could restore your OS from the recovery CDs but this will format your hard drive resulting in the loss of your data.

Windows XP will not boot up, and only gives a blue screen on Qosmio F20

I am having a similar problem to this:
http://www.techspot.com/vb/topic26409.html
The only solution to this is to reinstall/repair Windows XP Media Centre Edition:
http://www.techspot.com/vb/showthread.php?t=8356&highlight=windows+repair
This consists of reinstalling ONLY Windows (without formatting) the Recovery CD supplied with my computer cannot do this. I really do not want to format my computer, and being a sealed unit I do not want to remove the HDD from the laptop.
How can I carry out the process above with my current copy of Windows XP Media Centre supplied with the computer on the Recovery Disk?
Thanks in advance.
[Edited by: admin]

You could try to repair the OS using the XP repair console.
But the Toshiba recovery CD does not contains such console because its not a original Microsoft CD but it contains only a image files.
So if you want you can remove the HDD and connect it via external USB HDD controller to another computer.
Then you could get access to the HDD and could save all important files.

I changed the cracked screen on my 3gs, and screen works but it will not boot up and go past the Apple screen.

I tried recovery at least three times, and it says that it can not complete the activation at this time. I did take my Sim card out and try as well, because I had to use it in my old phone. I reopened the phone and double checked that everything was plugged back in from the screen change. What went wrong??? I restored it before and everything worked fine. It's not hacked or jailbroke, so I don't know what's going on???? Please help!

Yes, i did. I bought a screen repair kit and it was very simple to change. it works, but its stuck in recovery mode...

Windows 8 and Canvio Desk 3TB: System will not boot when external hdd is connected

http://h30434.www3.hp.com/t5/Desktop-Operating-Systems-e-g/HP-PAVILION-A6109N-amp-windows-8-System-w...
Hi,
just recently upgraded to Win Pro on my HP PAVILION A6109N. I also bought a toshiba canvio desk 3TB. What I notice is that if I reboot my pc with the extermnal HDD connected, my system will not boot.
I have check my BIOS boot settings and the order of the boot.
I have tried disabling USB Legacy Support in the BIOS
I have reformatted the external HDD
but still my desktop will not boot if the external HDD is connected....If I disconnect the external HDD...the system will boot up ....
I am at a loss....*** scratching my head ***

Update: The only solution for me was to format the drive as ext3 and plug it into one of my Asus RT-N66U USB ports, as most routers don’t yet recognize 3TB drives as NTFS. It’s not much help to people who don’t have a router with this capability, and it also slows transfer rates to ~12MB/s.
Given the short length of the cable, your only other options are to have the 3TB Canvio sitting right next to you so you can unplug from a front USB port before each boot, or place it towards the rear of your desk and crawl under the desk to disconnect it from your PC prior to each boot.
It's a pity because Toshiba produce great internal HDD's, but my experience when it comes to external drives is they're simply junk. I wish I had read the reviews before purchasing.

Operating reference system will not boot.

hi! bought the iphone 4s in Italy and it does not work. Operating reference system will not boot. Change of firmware and restore did not help. How can I change it while in Russia. Can I send in the mail store??

Hi NcBunky,
Are you using Win 7 64 bit? Did you update the Texas Instruments (TI) USB 3.0 XHCI Host Controller?
I have an H8 1380t PC. Updated the TI USB 3.0 driver and had the same problem.
When booting the PC with the USB 3.0 external drive connected to the PC the PC would not boot. When booting the PC with only the mouse, keyboard, and a USB 2.0 external drive attached the PC would boot. Once booted you could attach the USB 3.0 drive and it worked fine.
Solution was to roll back (reinstall) the TI USB 3.0 XHCI Host Controller to the original factory installed driver.
System now boots with the external USB 3.0 drive attached.

I am selling my Mac Mini. I recently purchased OS X Lion. When I restore to factory settings, how can I ensure that the operating system will still be Lion, and not the original operating system, which I believe was Snow Leopard?

If you bought Lion from the App Store, you can't legally or practically transfer it, because it's tied to your Apple ID. Reinstall the original software from the discs that came with the machine.

Satellite Pro M10 will not boot again and comes up with the error message

My Toshiba Satellite Pro M10 notebook will not boot again and comes up with the error message "load error" when I push the power button.
The problem arised after installation of "symantec system works" and trying to restart windows XP professional to make the installed program executable.
What can I do to get the notbook restart again?

Hi everyone
If you cannot acces to the boot menu by pressing F8 you can try to recover the the master boot record from Windows Xp professional installation Cd, to do this:
Attention: don't run these commands if you have more than one operating systems running in your laptop.
Boot from Windows Xp installation cd
Choose repair installation from console by pressing "C" key.
A console will open asking you for administrator password, insert the password and press enter.
Run de command: FIXMBR (It will write a new boot record)
Run de command: FIXBOOT (It will write a new boot file)
Restart the laptop and now windows should start without problems.

Apple Macbook 13.3" Laptop-Black 2008 2.4GHz Intel Core 2 Duo will not boot up and instead I get a grey screen with a folder and a question mark over it.

My Apple Macbook 13.3" Laptop-Black 2008 2.4GHz Intel Core 2 Duo will not boot up and instead I get a grey screen with a folder and a question mark over it. I've tried Option key, and Control S keys and it still will not boop up. Can anyone help?

If you are running Snow Leopard:
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU 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 failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
If you are running Lion or later:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU 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 failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it isthree times faster than wireless.

The system will not boot

Hello, I am trying to install windovws after the restart can not install Yosemite because can`t please format the hard disk.Please help because just yesterday bought macbooc

FYI...the top partition is too full. You need free space. You will need to remove the bottom partition then make the top partition larger. Make sure you have 10% or more free space. If you use Parallels or VMware you don't have to partition your drive. If you use the vm software you can run Windows wihtout having to reboot into bootcamp each time you want to use it.
See this link for help after you resize your top partition.
https://www.apple.com/support/bootcamp/
I forgot to ask...
If the system will not boot, how are you seeing Disk Utility. Are you booted from the Recovery Drive? If yes, then you will need to erase the internal drive and reinstall Yosemite on the internal. When you erase, make it one partition. You can add a second partition later that's smaller.
Note: you posted in the OS X 7 Lion instead of the Yosemite forum. In the future, asking on the correct forum gets the best answers.

System will not boot up

MB: KT6 Delta-LSR
CPU: XP2500 Barton
GFX: Asus V9520 Magic/T 128mb
RAM: 1028 pc3200 ddr400 (2x512) Geil Branded
HDD: Maxtor 40GB 2mb Buffer
Put it all together formatted the HDD, installed windows, network was working perfectly. (on ASUS via600 board)
Next day turn it on and nothing, zilch not even a flashing cursor top left of screen, dont even boot to DOS. screen is completely blank.
Tested CPU, GFX, RAM and PSU in another base unit and they work fine, yet put them all together and nothing.
1st I thought it was the mainboard so I sent the ASUS board back and ordered the KT6 Delta nice looking board. But still exactly the same problem.
Lights on case are lit all fans are turning ect yet still the system will not boot up i dont even get a flashing cursor top right of my screen.
There is no light with this mainboard for some reason.
All components work when fitted to another mainboard in a different case.
NB: one thing I have noticed is that there are two power sockets on this board,
1. The usual 20 pin socket (which I am connected to)
2. A 4 pin socket near to the CPU (whilst my PSU has a plug that will fit this sockect also, I am unsure as to connect instead of/as well as or leave unplugged.

Like I have stated before, it is the compatibility issue related towards your chip fsb and your memory fsb. I know that not everyone has money to go buy another stick of memory, I don't. But maybe you could exchange from the place you bought and say that it was a mistake? The cheapest route without getting the fsb chip to match the fsb of the memory stick is to get PC2700 memory. Have you tried going for this yet? I'm sure that your motherboard may not be shot, my board didn't get shot after trying to the two different fsb. You have to understand, motherboards are picky when it comes to running the hardware. If there is a conflict, it won't run right, I could run at a lower fsb and get it to work fine, but it wasn't at it's full potential, and I wasn't going to waste my time trying to find the fsb that would work correctly. So, I just let my friend have the stick back. This is why I'm asking you to try a lower speed stick of memory, because I have experienced this. But so far you haven't even seemed to notice my replies, could you take a quick overview of what I have said? Sorry if I come off as rude, just I am taking the time to write these replies and really am trying to help from my knowledge base. I have experienced this type of problem of what you are talking about personally.
Ok, so maybe I might not know it all, seeing that other people replying here have the same mb spec and chip fsb and memory like your trying to run, they might know more when it comes to that area for sure, just I didn't have luck trying to run a faster stick of memory compared to my chip, even though my board could run it, I couldn't get it to work, at all. I would just get a black screen, I thought I shot my GPU. Then I reset CMOS and the bios would flash, then when it would start pulling from harddrive, boom, black screen again. I had my friend tinker with my volt. to the right volts of the memory stick, still couldn't get nothing. This is why I am a little skeptical about you being able to run it at all in the long run. Hopefully you can find a way, maybe it is your manufacturer of your stick, but my conclusion is, if it isn't going to work with one, or two of same speed, try lowering it. Like I said, I tried it on this setup right now, and I didn't have to replace the chip or mobo, or gpu, so those should be fine.

System will not boot with Seagate 3Tb expansion drive plugged in.

I have a HP Pavilion HPE h8- 1214 Desktop , I recieved a Seagate 3TB expasion drive as a gift but when plugged in, the system will not boot. It turns on but thats it. It never gets to the boot sequence. I have it plugged into the top 3.0 usb slot and have tried all of the other slots as well with no sucess. But if I leave it unplugged the system boots right up. I can then plug it in and it works fine. I have plugged it into my wifes HP All- In- One and it boots fine and works. I have a WD 2TB drive that works fine as well on my system . I have searched Segates support for hours and all they say is to change the boot sequence. Have tried that, no go. What they dont get is no matter what I do if that drive is plugged in it never gets as far as booting and reading the boot sequence. Please help. Thank you!

Computer will not boot up. I have tried running disk utility and re-installing OSX. It says disk locked

I am new to Macs and have bought a 13" Macbook Pro and a IMac 21.5" 14 months ago. I have only used the Macbook pro about 15-20 times and after upgrading to Maverick it will not boot up. I get the white screen and a spinning circle. I have tried Disk utility repair and even re-installing the OSX, but it says disk locked. I do not recall setting any password protections or passwords. I now have a brick with a lit up Apple logo. If anyone knows how I can bypass the disk lock error or reset the laptop, please let me know. This has not been a pleasant conversion from PC's. Even my IMac blacks out from time to time and both happened right after my factory warranty expired.

The internal drive is malfunctioning. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
