Computer won't go beyond black screen won't boot

Hello all, I have a Mac desktop which is almost five years old. I turn on my computer, and you can hear it turn on but the screen is black. You can see the little power button flash but nothing happens. Any suggestions how to fix it?

The light in front is flashing? You may need to reseat the RAM chips. Take a look at this article: http://support.apple.com/kb/ht1432 Follow the steps to remove the RAM, but don't take it all the way out, just push it back in. Let us know.

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.

If usb is plugged the computer won't boot

Hi there. I have recently started to experience a new type of problem. I have two usb hdds connected to a usb hub. I've never had any problems with it(the hub). After I installed the last update 10.7.3 everytime I restart my computer if I have the hub (with all my hdds and other devices) connected to my computer, the computer won't boot. It get up to the white screen (before the loading wheel). If I unplug the usb cable it starts booting inmediately.
The funny thing is I didn't change anything lately. It started to do this yesterday.
Thanks

Is the hub powered? If not that is probably your problem. The hd's are sucking power but can't get enough to power up and that is probably stopping the MBP from booting.

Computer won't boot if the GTX 970 is plugged in

Hello everyone,
I just recently bought and assembled a new computer, however, the computer won't boot when the gpu is plugged in.
The motherboard I got is a MSI Z97I Gaming AC and the GPU is a MSI GeForce GTX 970.
When the GPU isn't plugged in the mobo, everything boots up fine and I was able to check with the bios that every other elements of the computer where recognized fine. When I plug in the GPU however, the system won't boot. The fans of the case, the mobo AND the GPU's are working and the GPU's leds also on, so it shouldn't be a PSU issue (I use a 750W PSU so that should cover it). However, no boot at all.
I don't really feel like trying to plug the GPU in another computer if it's just some compatibility issue or whatnot that you may be aware of. Maybe the bios doesn't recognise it ? The version is e7920IMS V1.0, I wasn't really able to find any kind of information regarding the latest versions online.
Thank you,
Yann

Here it is, follow the below to update to 1.4:
>>Use the MSI HQ Forum USB flasher<<
A.) Download the attached archive and place it on your desktop. Do not decompress.
B.) Download and install the Forum flash tool.
C.) Insert your FAT32 formatted usb stick.
D.) Make sure that all win 8 options are disabled. (Fast Boot etc) Also make sure the legacy USB is enabled.
E.) Start the forum flash tool and select option 1. Then point the tool at the compressed archive we downloaded earlier. Then to your USB Flash Drive.
F.) Boot to the USB
G.) Now follow the directions and let the tool flash
H.) After flashing reinstall ME drivers in Windows: http://download.msi.com/dvr_exe/intel_me10_mb.zip

Computer won't boot after installing MFP M127FW

My computer won't boot to my hard drive after installing my new MFP M127FW printer unless I first unplug the USB cable from the printer and then turn on the computer. My BIOS is set to boot from my hard drive, not from a USB drive, so what did the installation of the MFP M127FW drivers and software do to my computer? I assume this has something to do with the Smart Install feature.
This question was solved.

Hi @frcraig ,
I see that you are experiencing issues with the computer booting up when the printer is connected by the USB cable.
I would like to help you out with this issue today.
Most likely it is the Smart Install on the printer causing this. The printer looks like a disk drive.
On the printer, touch Setup, Service, Smart Install and turn it off.
If you are still having issues, in the system BIOS, disable the Boot from USB device option and the USB Legacy Support option. Doing this will allow the PC to complete the boot process to the internal hard drive and allow you to enter Windows. If this does not work for any reason, you should boot your PC before connecting the USB drive. Once the computer is fully booted into Windows, connect the USB drive and wait for the operating system to detect the drive.
Important: Do not disable the USB Legacy Support if you are using a USB Keyboard. Doing so will prevent you from being able to use the keyboard during the booting sequence.
What kind of computer do you have?
If you need further assistance, just let me know.
Have a great day!
Thank You.

My computer won´t boot and restarts at Apple logo with the spinning thing and I can´t get it to work.
Before this happen I had left the computer on without a cable plugged in and so it ran out of power.

Computer won't boot, all I get is a black screen

I'm using Vista home premium and everything was working fine up until the other day. My computer froze up and I shut it down to restart. Upon restarting, I was given the option to start windows normally or in safe mode. I selected to start up windows. After that all I got was a black screen. The computer is still running, I can hear the fans and the ligts are on.
I have been looking for a solution to this problem and would really like to fix it myself. I have tried all of the F-menu options, but all I get is the black screen. Vista came pre installed on my computer, so I don't have the Vista cd/dvd.
Please help me if you can.

Hi
May I ask you what computer you have?
Why you dont post this important information?
Can you boot in safe mode? Maybe a driver or virus has something muddled up in Windows registry and so the computer cant boot properly anymore.
In worst case you have to reinstall Windows using Toshiba recovery disk. :(

Computer Won't Boot Up

Here is my issue, my computer one day was working fine and the next it won't boot properly.
System Specs: Satellite T235D-S1345RD (Laptop) - Windows 7 (64bit) - BIOS 1.7 - 4gb RAM -
I have gotten the computer booted one time. I am unsure why it did that time but did not do it another time.
Since that one time I put the computer in hibernate and when I tried to bring it out it told me it failed when coming out of hibernate so it went to reboot and now won't boot.
Here are the few steps I have done to try and get it working. When it boots up it gives me an error message (says that power failed or for some reason it did not boot)
I have ran "Repair Computer" and it does not do anything. I try start windows normally and it goes no where.
So I then tried F8 and got into the Advanced Boot Menu. First one I tried was Start Windows From Last Known Good Configuration. (or something like that I forget the exact wording)
When it does that the computer will start to boot up go to the "Windows Loading" screen and then it flashes a blue screen (there are words there but it flashes so quickly I cannot read it) and it goes back to the boot screen and acts like it is restarting and continues in that loop.
Next step - Enter F8 again tried "Repair Computer" and it loads to a black screen with a Cursor but nothing ever happens. I have given it over 30 min and nothing happens.
So next step- I enter F8 again and try to boot up in safe mode and again when it loads it flashes a blue screen and then nothing.
EDIT - I found how to show the blue screen. It says UNMOUNTABLE_BOOT_VOLUME. Not sure what else I should do after I get that error message. Message Reads:
It reads UNMOUNTABLE_BOOT_VOLUME and says if it's the first time I've seen the error screen, to restart the computer. Then it tells me if it appears again, to check and make sure any new hardware or software is properly installed.
"If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode."
END EDIT
Next Step: I come to you guys here on this forum. I am a bit perplexed and lost at what to do. I wonder if this is a virus but I cannot get the computer to respond to try to get into it to check.
Ideas? Advice? What should I try? I can get into the F8 menu but not sure what else I should try. I will try anything to get this computer up and running!
Thanks for any and all help.

Hi:
The 24 character failure ID usually indicates HDD is failing/has failed. You need to replace it with a new one.
Specs: http://support.hp.com/in-en/product/HP-Pavilion-dv6-Entertainment-Notebook-PC-series/5191856/model/5...
Manual: http://h10032.www1.hp.com/ctg/Manual/c03099531
Check warranty: http://h10025.www1.hp.com/ewfrf/wc/weInput?cc=us&lc=en
Order recovery USB: http://support.hp.com/in-en/product/HP-Pavilion-dv6-6c13cl-Entertainment-Notebook-PC/5191856/model/5...
Contact HP: https://support.hp.com/in-en/contact-hp/product/HP-Pavilion-dv6-6c00-Entertainment-Notebook-PC-serie...
If you're under warranty, HP would send you replacement HDD.
If you're not, buy any branded 2.5" SATA 9.5mm thick internal laptop HDD and replace it yourself. But HDD of at least same capacity HDD as the one that came with your laptop (640gb) so that recovery media would work -
Go through page 56-58 in the Manual for replacement procedure. It's quite simple DIY job.
Something like this:
http://m.newegg.com/Product/index?itemnumber=N82E16822236561
If you've not yet created the Recovery media to restore the factory settings after replacement, you have to order a set of Recovery USB from HP.
For salvaging the data from old HDD, I suggest you take out the drive. Connect it to another PC using SATA to USB adapter - copy all the files you need.

Hi my mid 2012 MacBook air simply refuses to start. My charger is working which is a good sign but even in safe mode my computer won't boot up! I recently installed a product called WhatSizeMac.

As said above I just installed what size Mac and now my computer won't start. As soon as I downloaded it my computer was a little glitch but regarded it as nothing. my computer was later really buggy so I decided to restart it. My computer now will not restart/turn on no matter if it is in safe mode or not. In safe mode it gets around a third of the way and then the progress bar disappeared then the gear remains for a second then the screen goes black then that is it. By the way I have OS X Maverick's .1 or.2, maybe .3 but I doubt it. PS if you can tell me a legit application that will declutter all this space I seemed to have used, yet have no idea HOW! Thanks.

If SMC and PRAM resets do not bring back life to your MBA, make an appointment at an Apple store genius bar for a FREE diagnosis.

Computer won't boot properly

So with my pc, I have been having a problem where whenever I boot it up I will get the black screen of death.
Basically after I start it up, instead of the login screen I get a blank black screen with just a curser. I still hear the Windows chime.
However I can still boot into safe mode. I have determined that it is a graphic card problem because whenever I uninstall the drivers, it works just fine. No matter what drivers I use, it still won't work. I have a gtx 970. it works fine with Intel hd graphics 4600. Also if I wait 1 minute between each attempt it sometimes boots up after around 5 attempts.
I tried re-installing my os but that didn't work.
I found some fixes where you do control alt delete and open the task manager and restart explorer.exe but that did not work either.
Any more suggestions?
Thank in advance.

I have followed the format. I hope this helps a little...
Hi all, so I am having a problem with my newly built gaming desktop. Whenever I boot it up, instead of showing the login screen it shows a black screen with a cursor. Whenever I login, (I can still type in my password) I see a blank desktop with just my background. Also if I keep it idol for long periods my explorer.exe will stop working and my desktop will disappear and just show my background.
Sometimes after about 5 attempts to boot it will succeed and boot normally. (If I wait about a minute between each attempt)
These are the things I have tried:
1. changing video card drivers
2. attempting to restart explorer.exe (unable to access task manager)
3. re-installing Windows
4. using integrated graphics (worked just fine)
How I isolated the problem: I am still able to access safemode. I disabled my video card driver and my computer now works just fine. Whenever I enable it my problem continues. Also when it will boot up everything runs perfectly. My games run just as they should.

Installed Safari 3.1, reboot, computer won't boot fans go into overdrive

Okay, I installed the Safari 3.1 update and restarted my computer. However it won't boot now. The displays stay black and after about 30 seconds the fans in the G5 kick on full blast.
I've tried shutting it manually and unplugging the power cord from the back. I also tried zapping the PRAM.
Help? I would appreciate it.

My computer is also now not restarting. First Safari 3.1 had other apps stop working and now the computer won't restart. I tried Safe Boot and zapping the PRAM but it just cycles through two different blue screens.

Video card fan dying, tried to replace card, computer won't boot

This Pavillion came preinstalled with an nVidia GeForce GT 630 graphics card. The fan on this card is going bad - the card smells "burny" when I run it, the fan runs really loud and the computer is crashing while playing graphics-heavy games.
I tried replacing it with a PNY Verto GeForce GT 730 2048 MB DDR3 card. But now, with the Verto installed, my Pavillion won't boot up, it just hangs on the HP splash screen. I cannot boot in Safe Mode nor can I access BIOS settings.
The Verto's specs seemed like it would work in my Pavillion - PCIe 2.0, at least 300W PSU. I've been searching online for help but am unable to determine a fix for my problem.
Any tips?
This question was solved.
View Solution.

I checked the support page for my Pavlillion and I noticed an updated driver for my computer's BIOS. I got that installed and it seems to have fixed the problem.
