Compaq CQ56 Laptop/Will not reboot/black screen

Hi...I am new to this forum...I have a Compaq CQ56 laptop....just recently while updating my spyware and installing my updates, when the system reboots the screen remains black....I launch the system repair...it takes me to the system restore window...did the system restore and the computer rebooted just fine....however everytime I need to install an update and reboot...I run into the same issue each time. Ran the Hard disk and Memory diagnostic test and that passed without any issue. I did notice a loud noise which I assume was coming from the fan....not sure.
Update for Windows 7 for x64-based Systems (KB2762895) failed at the install. Is there another fix outside of having to take in for repair?
Thank you for your time

Hello Nana53
Do you only run into the problem when you try to install just the Windows 7 update (KB2762895) or does it happen when trying to update any application? You said the screen is black, so how did you perform the system repair? Are you referring to the black screen as the screen goes black while windows is trying to load and you do see the BIOS and boot options?
Searching the internet I have found mixed feelings and problems with users installing the Windows update. It seems to be meant to improve compatibility of programs, however, some applications aren't liking the changes.

In your case it isn't working. You can hide it from view so that you don't need to update it. This should prevent the problem from reoccurring. Hide Windows 7 Updates that you do not Ever Want to Install
For more information about the update and/or if you want to try manually downloading and installing it check out the link below.

Mac book pro Computer will not start black screen

Will not boot - Black screen A2 code on bottom right.

mobo:Z97S SLI KRAIT EDITION
Samsung SSD - Windows and games are installed here
WD HDD - Everything else is put on this one.
Windows 7
I installed an ISO mounting program called Gizmo Central onto my HDD
After installation it said that it needed to restart. After it restarted I got a black screen with an A2 code. The screen will go completely black, and then it will back to the screen with the A2 code in the bottom right. It won't boot up BIOS, unless I do 1 of 2 things:
1. power off the pc, unplug the sata cable from the HDD, power pc back on, bios and windows will boot up. I can then turn the pc off, plug the sata cable back into the HDD, and it boots up fine into windows, but if I reboot again, it goes back to that black screen with the A2.
2. I have put in a disc into the dvd drive, and I do not get that screen. (I've been doing this as a workaround since it's much easier)
I have tried a number of things to resolve this, but none of them have restored my computer to it's perfect working order that it was previous to installing this program.
When I tried to uninstall that program it wasn't even on my installed programs list, so I deleted the folder it was in. This didn't resolve the issue.
I have wiped everything off of my HDD drive. This did not resolve the issue.
I have triple checked that my SSD is the first in the boot order. I even disabled the HDD from the HD boot order entirely. No change...
I updated my motherboard drivers. No change.
It's almost like for whatever reason my BIOS isn't listening to the boot order and doing my DVD drive, HDD, and then the SSD ever since I installed that Gizmo ISO mounting program.
I set the BIOS to factory default settings. That did not fix this issue.
I have use a windows system restore point from 2 days ago when it was working flawlessly. No change.
I'm thinking about reinstalling Windows, but logically it doesn't make sense to do that since the error happens even if I power off/on from BIOS with the HDD plugged in, so it I'm willing to venture that it's not Windows at fault here.
Also the computer used to boot up in like 8 seconds. It's still fast to boot up, but ever since this started to happen, it takes like 15-30 seconds for my usb mouse, and usb keyboard to register after windows starts up. It use to be immediate. My computer is so messed up right now, and I don't even know how it got like this or how to fix it. I'm pretty savvy and can follow directions well, so any help would be greatly appreciated.

What intel USB driver version do you use? There's one more thing to try, try plug the kb/ms to USB 3.0 ports except the ones under the LAN port, and check if it happens again.
I'm glad you recommended checking Intel drivers. I typed appwiz.cpl to go to the installed programs list in windows. Found "intel USB 3.0 extensible host controller". I tried uninstalling this. It made my mouse and keyboard not work for about 1 minutes. Windows downloaded some drivers for my devices, and asked to reboot. I rebooted. Mouse/keyboard responded right away! Just incase it was a fluke I rebooted another 2 times, and each time the mouse and keyboard are immediately responsive. I'm SO glad that my PC is back to it's original working order. Thank you to you all for taking time out of your day to help me. I really appreciate it!

Imac will not boot. black screen, no sounds.. but has power.

Hi guys, yesterday my mac would not boot. The screen is black, and the power light on the bottom right hand corner is on. My warranty expired 30 days ago (figures). I stupidly put in a CD to see if the player had power and it did (now I can't get it out). I can hear the fan on, and the DVD drive spinning. I have no chimes or sounds. I removed the memory and started the machine... same thing except the power light started flashing. I put the memory back in and powered it up.. same as before solid light, black screen, and no sounds. I unplugged the unit for a day which did not help. ANY help would be appreciated!
Imac - Intel Mac OS X (10.4.9)

First, boot and hold down mouse key to get CD out. then,
Try this.
Turn on Mac and hold down command-S (Apple S), it will boot into single user mode (white on black). Let it finish.
When it is done type the following.
fsck -fy
then hit return. It will check the disk and make repairs. It can take several minutes. If it finds errors it will fix and say OK. If so, type fsck -fy and run it again. This time if it doesn't find any errors type
reboot
Hopefully it will boot into OS X.

System will not boot / black screen

:undecided:Problem: System does not boot. Black screen.
I just put this system together. I've returned the CPU and motherbd. for exchange, thinking one may be defective. Still No Boot. PowerSupply checks out good. MSI video card checks out good too. Could it be the memory stick? Pls. HELP. BTW - Yes, I did remember to plug in the 4-pin power connector.
Motherbd: MSI 865PE Neo2 (option2) (New)
CPU: INTEL P4 2.4G 1 MB L2 533MH (New)
http://www.newegg.com/app/viewproductdesc.asp?DEPA=0&description=19-116-141&ATT=Processors&CMP=OTC-B1zrat3
Memory: 1 dimm - 1GB PC2700 333MHz DDR SDRAM
http://www.ocsystem.com/1gbpc33ddrsd.html
VGA : MSI Video Card - Geforce FX5200-TD128 128MB TV-Out DVI-I (Tested Good)
http://www.ussa.com/ussaonline/product.asp?dept%5Fid=10610&pf%5Fid=100%2D106%2D1004159
PowerSupply : Enermax EG365P-VE-FC 350W (Tested Good)
HardDrive : 120GB WesternDigital

You got me there. I only looked at the LED's after it hangs.
I must wait for my reshippment of my memory. I returned it, and asked them to test it. If it tested good, then it probably not compatible with system. My next option was to order GIGARAM 1GB, since it is on the list of recommended DDR.
Sorry, I cannot reboot at the moment. Do you think it is the memory, or something else?
Thanks,

Will not reboot? screen has a lite glow but will not reboot?

My phone will not Re -Boot? The screen has a light glow to it and I can hold down the power switch. After 30 seconds or so, the screen goes blank - that's it?

Make sure you are connected to power (ie not running off battery).
If you still have the black screen and can't get your Mac Book Air to turn off hold the power button until it shuts off.
Try a normal power on and if you get the same issue try a safe power on by holding the shift key during boot up. If you can't do a safe boot up try doing a recovery boot by holding the command key + R key during boot up and run disk repair.
If you are still having issues contact Apple for service.

Z97 PC MATE - Second GPU will not display / black screen

Using Z97 PC MATE with 2 nvidia cards (GeForce GTX970 and GeForce GETX750ti). My goal is to use the 750ti for dual display with the 970 reserved for compute in a 3D software package (houdini simulations). If both cards are installed on the mobo and one monitor is plugged into the 750ti, it will not display, not even the BIOS screen. Also there is no audio, there is normally a chime when the OS lock screen is reached and that never plays.
The 750ti is plugged into the PCEe 2.0 slot, the 970 the 3.0 slot. Both cards can display in their respective buses by themselves if only one card is installed. If both are installed, the 970 will output a display as expected. I have also tried an older quadro card in the 2.0 slot and it also defaulted to the 970 in the 3.0 slot. With one display plugged into the 970, and one in the 750ti I have gotten an image to display on the 750ti. But never with only one monitor plugged into the 750 attempting to use that card as the main display.
I have used m flash to update the bios to 4.6, but I never used the disc which came with the mobo to update. I thought maybe there is a GPU display priority in the BIOS but I'm not seeing it. I see there is a way to prioritize UEFI and legacy, and Gen1, 2 or 3, but don't know how that should be set up for this (if that is the problem). I would think if that were the case though the audio at the lock screen would still play, but I don't know.
My current nvidia driver version is 342.22, I am using Ubuntu 14.04 as linux OS operates better with the software I am using. I have also posted to the Ubuntu forums about this, but thought I would post here because the BIOS screen doesn't display which makes me think it could be hardware related. Although all of the hardware is detected properly and appears to be functioning as expected.
This issue was reproduced with and without the HDD connected.
Hardware:
i7 4790k
EVGA GTX970 and EVGA GTX750ti
Z97 PC MATE
32gb PNY DDR3-1866 240-pin DIMM
Antec Truepower Classic 750w gold certified
PNY Optima 480gb SSD - PNY SSD7SC480GOPT-RB
Hitachi 2TB ultrastar HDD
I am not sure at this point how to continue troubleshooting this issue, or if this is not possible for this mobo and I just didn't recognize that. One test I was considering is putting the 970 in my old computer (MSI 970FX-GD70) and seeing if the results are the same. Will post any additional required information.
thanks!

Did you install your graphic driver when both vgas are on? Let the driver detect both vga then you can just switch cable and display well. Use the latest 344.65 driver. As for the 3D package, you need to make sure the software support or can change the settings that which vga to compute.
But there's one thing I need to make sure first, does your vga work with only one vga on pcie 2.0 slot? Just wanna be sure it's not faulty slot...

Mad Men shows will not play - black screen, no sound

Black screen and no sound when trying to play Mad Men shows. Video podcasts play fine.

Opened the videos with QuickTime. Plays perfectly.

Iphoto will not open, black screen comes up and will not let me rebuild. what do i do to fix this problem?

this is the message that comes up when i try to rebuild it or do anything to it as far as opening iphoto:
your photo library is either in use by another application or has become unreadable
… shut down and restart your computer then open iPhoto again. if that problem persist. try rebuilding your photo library. to do this, quit iPhoto and then reopen it while keeping the option and command keys pressed. you can also try restoring your photo library from a back up.

Remember to hold both the alt and command keys while launching to get the rebuild menu.
If that fails then your options are
Restore from your back up
or
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Laptop will not reboot after full recovery

Hi,
G61-401SA Notebook: Windows 7 64-bit.
I have replaced a fault hard drive and used the Recovery Disk set to re-install. All software loaded and it said to remove disk and continue to reboot.
I done this and it just comes back with – ‘No Bootable device – insert boot disk & Press any key’
I have run the recovery several times, however each time it comes up with the same problem.
Does anyone know what I can do or how to fix this ?
Thanks
This question was solved.

@Jedimanjs
Sometimes it helps to prep the hard drive with Cyberlink Utility cd first. Download and Save the file. Once download is complete, put a blank cd in your drive and click the file to create a boot cd. Boot with this cd and wait until you get a green check mark indicating hdd is ready. Remove the cd , insert first Recovery Disk and restart the laptop.

Your iPhone is in recoverty mode at the moment so to possibly get it back up and running you would need to do a restore as you have been trying. Follow the steps in the article below for the specific error messages you have been receiving. If after following all steps the issue remains book an appointment at a local Apple Retail Store to have the iPhone evaluated.

TS3274 My ipad display will not function, the screen will not display anything when turned on, you can see that the screen lights up but it is completely black

The screen on my iPad will not display, the screen lightens up when powered on but the screen stays black, any fix for this that I can do at home?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
